A pneumatic breaker spare-parts RFQ should identify the exact tool before it identifies the part. At minimum, send the breaker manufacturer or accepted product family, complete model designation, serial number or production revision when available, the correct parts-book or exploded-view reference, required quantity, clear photos, and the delivery destination. A request such as “send one piston for a 35 kg breaker” is not enough: tools with similar appearance or weight can use different valves, pistons, retainers, bushings, seals and repair kits.
The safest purchasing sequence is tool identity → drawing revision → component reference → order quantity → commercial and delivery terms. If any link in that chain is uncertain, ask the supplier to confirm the match in writing before production or shipment. This guide explains how maintenance teams, distributors and industrial buyers can build a quotation request that is fast to review and less likely to produce a wrong but visually similar spare.
What information belongs in a pneumatic breaker spare-parts RFQ?
| RFQ field | What to provide | Why it controls the match |
|---|---|---|
| Tool identity | Manufacturer or accepted product family, full model, type suffix and photos of the complete breaker | A short model name can cover more than one construction or market version. |
| Serial or revision evidence | Serial number, production code, nameplate photo, manual edition or parts-book date if available | Parts can change at a serial break or drawing revision even when the model name remains familiar. |
| Component reference | Part number, exploded-view item number, part description and parent assembly | An item number points to a drawing location; it is not always the orderable part number. |
| Physical evidence | Photos of the old part, markings, wear location, mating parts and critical dimensions | Evidence helps resolve missing or ambiguous documentation, but should not replace known model data. |
| Quantity | Quantity per tool, number of tools to service, order quantity and desired spare allowance | The quantity shown in a parts list may mean quantity used in one assembly, not the quantity you intend to buy. |
| Supply form | Individual part, service kit, repair kit, overhaul kit or complete subassembly | A kit may include seals and small items that are not included with one loose component. |
| Commercial destination | Required date, destination country/port, shipping preference and documentation needs | Availability, packing and freight options affect the usable quotation. |
1. Identify the breaker before naming the part
OEM parts systems commonly start with a model, serial number or product family because that information narrows the applicable parts book. The serial number is especially useful when a manufacturer changed a component during production. If the plate is damaged or missing, do not silently substitute an estimated model. State that the identity is uncertain and provide more evidence.
Photograph the complete breaker from both sides, the handle and throttle area, air inlet, cylinder or barrel, front head, chuck and retainer. Add a close-up of every plate, casting mark or stamped number. The aim is not to make the supplier guess from color; it is to show the design features that can be compared with a drawing.
When several breakers are in the fleet, identify each unit separately. Do not assume that tools bought in different years use the same internal revision. A fleet list should connect every serial number to the parts-book edition and any supplier-confirmed substitutions already used on that tool.
2. Read the exploded view without confusing its references
A parts drawing usually separates the tool into assemblies and gives each component an item or reference number. The adjacent list may show an orderable part number, description, quantity and remarks. Those fields have different jobs:
- Item or reference number: locates the component on that particular drawing.
- Part number: identifies what can be ordered, subject to revision or supersession.
- Description: helps confirm function, but names can vary across manufacturers.
- Quantity: often means how many are used in one tool or parent assembly.
- Remarks: may indicate a kit, serial range, replacement number, non-separable assembly or optional version.
Copy all relevant fields into the RFQ. “Item 18” by itself is unsafe because item 18 in another manual or revision can be a different component. If the part is nested inside a handle, valve, cylinder or retainer assembly, name that parent assembly as well.
Check whether the requested component is sold separately. Some small seals, pins or valve elements may be supplied only as a kit or complete subassembly. Conversely, ordering a complete assembly when only a service kit is required may add cost without solving the underlying maintenance question.
3. Control serial breaks, superseded numbers and aftermarket claims
A familiar part number can be obsolete, superseded or valid only within a serial range. Ask the quotation to show both the number you submitted and the supplier’s proposed current number. If they differ, request the cross-reference basis and the applicable model or serial range.
Do not treat “replacement for,” “compatible with” and “same dimensions” as equivalent claims. A sound confirmation should state which exact breaker model and revision the offered part fits, whether it is an individual component or kit, and whether any mating part must also change. For critical impact components, visual similarity is especially weak evidence because material, heat treatment, clearances and port geometry are not established by an outside photo.
If the quotation proposes a substitute, ask for a controlled description: offered number, original reference, brand or manufacturing basis, compatible model/revision, included items, exclusions and any installation condition. This makes technical review possible before the purchase order is released.
4. Use photos and measurements when documentation is incomplete
Photos and dimensions are fallback evidence, not a license to reverse-engineer a safety-critical part from one worn sample. Begin with clean, well-lit images of the entire component from several angles. Include markings, ports, grooves, shoulders, contact faces and the location where it fits in the tool. Place a ruler or caliper in a separate measurement photo rather than obscuring the part.
Record only dimensions that the supplier says are relevant to identification. Depending on the component, these may include overall length, major diameters, thread form, hole spacing, groove location or shank geometry. State the instrument used and whether the old part is worn, deformed, broken or corroded. A worn diameter is not automatically the original manufacturing dimension.
Also photograph the mating component. A damaged retainer, bushing or front head can change how a new part fits, and replacing only the visible broken item may leave the real cause in service. If a component failed, add a short symptom and failure-location note instead of sending only a loose-part photo.
5. Decide whether you need loose parts, a service kit or an overhaul package
OEM service programs often group commonly replaced wear items into predictive-maintenance, repair or overhaul kits. A kit can simplify identification and ensure that related seals or small retaining items are available during service. However, kit contents are model-specific and should be confirmed rather than assumed.
Ask the supplier to itemize:
- kit name and order number;
- all included components and quantities;
- applicable breaker model and serial range;
- parts not included but normally inspected during the same repair;
- whether installation instructions or a parts drawing are supplied;
- whether special tools, measurements or qualified workshop work are required.
For planned stock, separate three needs: routine consumables or working tools, predictable maintenance parts, and low-frequency corrective-repair components. The right mix depends on fleet size, duty, lead time, service history and whether repair is done on site or by an external workshop. There is no universal “one kit fits every breaker” stock list.
6. Convert maintenance demand into an order quantity
Start with the number of breakers covered by the RFQ and the planned service event for each. Then distinguish:
- Installed quantity: how many of the item one breaker or parent assembly uses.
- Service quantity: how many are required for one planned repair.
- Fleet quantity: service quantity multiplied by the number of confirmed applicable tools.
- Stock allowance: additional quantity justified by consumption history and replenishment lead time.
- Order quantity: the final amount requested after checking pack size, kit content and minimum order conditions.
Do not multiply a drawing quantity until you know whether the supplier sells the part individually, as a pair, in a kit or only within an assembly. Ask the quote to show unit of sale and pack quantity so the purchasing line cannot be interpreted two ways.
7. Compare quotations on technical equivalence before price
Two quotations are comparable only when they cover the same technical requirement. Build a bid-comparison line for each item with the submitted reference, offered reference, compatibility basis, supply form, included quantity, unit of sale, lead time and exception notes.
| Comparison check | Acceptable evidence | Red flag |
|---|---|---|
| Model applicability | Exact model/revision or serial range stated | “Universal” or “looks the same” without controlled scope |
| Part identity | Submitted and offered numbers cross-referenced | Only a generic part name |
| Kit content | Itemized components and quantities | “Complete kit” without a content list |
| Revision | Supersession or drawing revision disclosed | Changed number with no explanation |
| Quantity | Unit of sale and total quantity explicit | Pair, set and piece used interchangeably |
| Exceptions | Missing items and installation conditions listed | Silence where the RFQ requested confirmation |
Price review should follow this normalization. A lower-priced line may exclude seals, retainers, packaging, documentation or another component included in a competing kit. Clarify the difference before deciding that one source is cheaper.
Common RFQ mistakes that cause wrong-part orders
- Ordering from tool weight, color or a shortened model nickname.
- Sending an exploded-view item number without the drawing edition and part number.
- Using a worn component’s measured diameter as the original specification.
- Assuming all tools in a fleet have the same serial revision.
- Failing to distinguish one piece, one pair, one set and one kit.
- Accepting a superseded or aftermarket number without an applicability statement.
- Requesting “all seals” without the model-specific kit content.
- Omitting the symptom and mating-part condition after a repeated failure.
- Comparing prices before aligning scope, quantity and inclusions.
- Leaving destination, required date or documentation needs until after quotation.

Frequently asked questions
Is the exploded-view item number enough to order a pneumatic breaker part?
No. The item number only identifies a callout on a particular drawing. Include the parts-book edition, page or assembly, orderable part number, description, tool model and serial or revision information.
What if the pneumatic breaker nameplate is missing?
State that limitation clearly. Send complete-tool photos, casting or stamped markings, air inlet and handle details, chuck and retainer views, old-part photos and any purchase or service records. Ask the supplier to identify what remains uncertain before accepting the order.
Should I order an individual part or a repair kit?
Use the diagnosed maintenance scope and the model-specific parts information. A kit can be useful when related seals and small components are replaced together, but confirm its contents, applicability and exclusions. Do not assume the phrase “repair kit” has a universal content.
How should a supplier confirm a superseded part number?
The quotation should show your submitted reference, the proposed current reference, the applicable model or serial range, whether mating parts also change, and the supply form. Keep that cross-reference with the fleet’s maintenance record.
Can photos and caliper measurements prove compatibility?
They can support identification, especially when documentation is incomplete, but they do not prove material, heat treatment, internal geometry, clearances or revision. Use them with model and drawing evidence, and obtain written supplier confirmation.
Prepare the evidence before asking for price
A strong pneumatic breaker spare-parts RFQ gives maintenance, procurement and the supplier the same controlled reference. Identify the exact breaker, tie the component to the correct drawing, state the supply form and quantity, document uncertainty, and ask for compatibility and substitution decisions in writing.
For a review of a pneumatic breaker, working-tool or related spare-parts requirement, submit the model, serial information, drawings, photos, quantities and destination through the PerfoMax quotation form. The more complete the identification package, the easier it is to separate a technically supportable offer from a visually similar guess.
