What to specify in your RFQ

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

  • Material / compound

    Specify elastomer type (FKM/Viton, NBR, EPDM, PTFE, PEEK, Aflas) and any subsea-grade or low-temperature variants required.

  • Pressure rating & backup design

    Provide maximum operating pressure and whether back-up rings or reinforced geometries are required for extrusion resistance.

  • Dimensions & tolerances

    Give internal/external diameters, cross-section, and tolerances or drawing files for custom sizes.

  • Quantity & production cadence

    State initial order size, expected annual volumes, and whether you need prototype, batch, or continuous supply.

  • Standards & testing

    List required standards (e.g., NORSOK, ISO, API) and tests (compression set, helium leak, ageing, hydrostatic) for qualification.

  • Operating environment

    Describe subsea depth/temperature range, chemicals, and dynamic vs static sealing to guide compound selection.

  • Traceability & certifications

    Request material certificates, manufacturing lot traceability, and relevant factory certifications (e.g., ISO, NDT records).

Sourcing FAQ

How do I verify a supplier actually manufactures high-pressure subsea O-rings?
Ask for factory photos, manufacturing process details (compression/molding/trimming), sample part numbers, and certifications; suppliers that state 'we manufacture' or show product pages and factory domains (e.g., .sg pages) demonstrate production capability.
What determines minimum order quantity (MOQ) for custom subsea O-rings?
MOQ depends on tooling and material — standard sizes often have low MOQs, while custom-molded or certified subsea compounds require higher initial runs to justify tooling and testing costs; confirm with the manufacturer.
Which certifications or tests matter for subsea high-pressure O-rings?
Relevant items include material certificates, compression-set and ageing tests, compatibility testing with media, and compliance to industry standards you require (API, NORSOK or customer-specific specs).
What drives lead time for high-pressure subsea O-rings?
Lead time is driven by material availability (special compounds), requirement for custom tooling, qualification/testing cycles, and production scheduling; ask suppliers for a breakdown of prototype, testing, and serial production timelines.
