What to specify in your RFQ
Manufacturers quote faster and more accurately when your request covers these points.
- Material (rubber, PTFE, compressed fiber, metal, composite)
Specify the sealing material and any required compounds or temperature/chemical resistance to match media and service conditions.
- Dimensions and tolerances
Provide gasket type (ring, sheet-cut, die-cut, spiral-wound), nominal dimensions, thickness and tolerance range or drawing/PDF.
- Pressure, temperature and media
State maximum operating pressure, temperature range and the fluids/gases the gasket will contact so manufacturers can select appropriate materials.
- Standards and certifications
List any required industry standards (ASME, API, DIN) or quality certifications (ISO 9001, PED) that the supplier must meet.
- Quantity and production timeline
Specify initial order quantity, expected annual usage, and required lead time to allow accurate quoting and tooling considerations.
- End-use and installation method
Describe flanges, surface finish, bolt pattern, and whether gasket is for OEM, maintenance spares or new equipment design.
- Required testing or traceability
Indicate if you need material certificates, lot traceability, test reports (e.g., leak testing, hardness) or serialization.
