# Parts, Seals & Replacement Components — RFQ template & spec checklist

_Generated by PostRequest (postrequest.io). Free to copy and adapt._

This category covers the maintenance and repair inventory that keeps installed equipment running: mechanical seals and O-rings, gaskets, bearings, gearboxes and motors, pump rotors and wear plates, valve repair kits, drive belts, and instrument spares. Plants buy here against a breakdown, a planned overhaul, or a stocking review, and increasingly to qualify an aftermarket source against OEM list prices. Fit, material, and duty rating have to match exactly or the repair fails early, and product-contact elastomers carry their own compliance requirements. Because aftermarket and OEM parts can differ in metallurgy and tolerance, competing quotes pay off — but only against a verified part specification.

## Example RFQ
Need quotes on product-contact seals and gaskets for a sanitary centrifugal pump and related tri-clamp connections. OEM pump is a common food-grade model; we can provide make/model/serial and the faded OEM seal kit number, plus shaft diameter and seal-chamber measurements if the revision is unclear.

Duty: beverage product with periodic caustic/acid CIP and hot water sanitizing. Prefer FDA food-grade / 3-A suitable elastomers that tolerate our CIP chemistry and temperature. Looking for OEM or qualified aftermarket equivalents with material certificates. Quote unit price for the immediate repair kit (qty 2) plus recommended critical-spare stocking qty, lead time for stock vs expedite, and any warranty notes. No plant name on quotes — we will connect only if we proceed.

## What to include in your request
- [ ] Equipment make, model, and serial number, plus the OEM part number and any revision level
- [ ] Function and duty: pressure, temperature, speed, media, and CIP or SIP exposure
- [ ] Dimensions verified by measurement where the part number is uncertain (shaft size, bore, bolt pattern)
- [ ] Material spec: seal face pairs, elastomer compound, bearing grade, and gasket material
- [ ] For product-contact seals and gaskets, FDA food-grade and 3-A sanitary elastomer compliance
- [ ] OEM versus qualified aftermarket acceptability, and any warranty or documentation requirement
- [ ] Quantity for the immediate repair plus the critical-spare stocking level and required delivery date

## What drives the quote
- OEM-branded part versus qualified aftermarket equivalent
- Material grade: seal face materials, elastomer compound, and bearing precision class
- Order quantity and whether it is a stocked line item
- Expedite and freight for an emergency breakdown order
- Documentation: material certificates and food-contact compliance statements

## Common spec mistakes to avoid
- Ordering by a worn part's faded number without verifying dimensions or revision level
- Substituting an elastomer that will not tolerate the CIP chemistry or process temperature
- Buying the cheapest bearing without matching the OEM precision or clearance class
- Overlooking food-grade compliance on product-contact O-rings and gaskets
- Stocking to price rather than to criticality, so the parts that cause downtime are not on the shelf

## Lead time
Common bearings, belts, and standard elastomers are usually on the shelf; OEM-proprietary assemblies, large gearboxes, and custom seal configurations can take much longer. Expedited freight is often available for a breakdown at a premium.

## Anonymity
Your request posts anonymized — suppliers see the category, spec, and state only. Name and contact details are shared with a supplier only if you choose to connect with their quote. No account required.
