What to specify in your RFQ

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

  • Pipe size (nominal diameter)

    Specify the pipe nominal sizes and any range (e.g., 1"–12") so the supplier can confirm compatible fitting sizes and stock availability.

  • Outlet type and size

    For mechanical tees state the outlet size and type (grooved, threaded, flanged) and whether the outlet is reducing or same-size.

  • Material and grade

    Give the required fitting material (e.g., ductile iron, 304L stainless, 316L stainless) and any material standards (ASTM numbers) you require.

  • Pressure rating and standards

    Specify required working pressure or class (PSI/bar) and any required approvals (UL, FM, ANSI) used in your application.

  • End connection (groove profile/standard)

    State the groove profile or standard (Victaulic, ANSI/AWWA, other) to ensure mating couplings fit correctly.

  • Quantity and lead time

    Provide order quantity (and anticipated repeat volumes) and desired delivery date so suppliers can quote MOQs and lead times.

  • Coating/finish and gasket compound

    Indicate any coating (epoxy, paint) and gasket material preferences (EPDM, nitrile) required for service conditions.

  • Application and certification needs

    Describe application (fire protection, HVAC, waterworks) and ask for certificates (UL/FM listings, material mill test reports) relevant to that use.

Sourcing FAQ

How do I verify a supplier actually manufactures grooved fittings or mechanical tees?
Ask for factory information, product datasheets showing part numbers and materials, UL/FM listings if applicable, and photos of production or casting/forging processes. Use suppliers' own product pages (linked above) as initial proof.
What typical minimum order quantities (MOQs) should I expect?
MOQs vary by producer and product complexity — some manufacturers or foundries will accept small orders, while cast or stocked items may have higher MOQs; request exact MOQ from each supplier when you request a quote.
Which certifications matter for fire-protection grooved fittings?
UL and FM listings are commonly required for fire sprinkler systems; also check material certifications (ASTM) and manufacturers' conformity statements for pressure ratings.
What drives lead time for grooved fittings and mechanical tees?
Lead time is driven by material availability, whether items are stocked or need casting/fabrication, required coatings or custom outlets, and certification/test documentation — clarify these up front when requesting a quote.
