What to specify in your RFQ
Manufacturers quote faster and more accurately when your request covers these points.
- Pipe size / nominal diameter
Specify the range of pipe diameters (e.g., 1"–8" or larger) the coupling must fit.
- Material and finish
State required materials (ductile iron, stainless steel, aluminum, rubber gaskets) and corrosion protection or coating.
- Pressure rating / schedule
Provide the design pressure or system standard (PSI / class) the coupling must meet.
- Standards and listings
List required third‑party listings or standards (UL/FM for fire protection, ANSI, ASTM).
- Quantity and unit mix
Give total quantities, any breakdown by size, and whether components must be from a single manufacturer.
- End connections and tolerances
Specify grooved-end standards, pipe wall tolerances, and whether adapters or flanges are needed.
- Gasket material and temperature range
Specify gasket compound (EPDM, neoprene, etc.) and operating temperature/chemical exposure.
