What to specify in your RFQ

Manufacturers quote faster and more accurately when your request covers these points.

  • Gasket material

    Specify the base material (rubber type, PTFE, graphite, metal, composites) because sealing performance and chemical compatibility depend on it.

  • Operating temperature and pressure

    Provide continuous and peak temperature ranges plus maximum pressure to ensure the material and construction are suitable.

  • Dimensions and thickness

    Give inner/outer diameters, cross-section profile, and thickness/tolerance so the manufacturer can select cutting, stamping, or molded processes.

  • Quantity and order cadence

    State single-order quantity and expected recurring volume to determine production method (die-cut, molded, or stamped) and tooling needs.

  • Applicable standards and certifications

    List required industry standards (e.g., ASME, ISO, FDA, ATEX) or customer-specific certifications to confirm compliance requirements.

  • Media / chemical exposure

    Describe fluids, gases, or chemicals the gasket will contact to check material compatibility and lifespan.

  • Surface finish and coatings

    Specify whether you need metal facings, coatings, or surface treatments (e.g., anti-stick, conductive) that affect sealing and durability.

Sourcing FAQ

How do I verify a gasket supplier is a manufacturer and not just a distributor?
Ask for explicit statements about manufacturing capabilities (in-house die-cutting, molding, extrusion, or stamping), photos or descriptions of production equipment, and references for OEM supply; the provided evidence samples show suppliers declaring 'we manufacture' or 'manufacturer' in their own descriptions.
What typically determines minimum order quantities (MOQs) for gaskets?
MOQs depend on whether parts require custom tooling or are simple die-cut from roll stock; molded or stamped parts with dedicated tooling usually have higher MOQs than cut parts from standard sheets or rolls.
Which certifications should I request from an industrial gasket manufacturer?
Common credentials include ISO quality management (e.g., ISO 9001), material-specific approvals (FDA, NSF for food contact), and compliance with relevant industry standards (ASME, API) depending on the application.
What drives lead time for custom industrial gaskets?
Lead time is driven by complexity (custom tooling or molds), material availability, required testing/certification, and order quantity; simple die-cut parts from stocked materials are fastest, while new-molded or certified parts take longer.
