Fittings Terms and Definitions

Dryseal pipe threads – Tapered pipe threads that are covered by American National Standards Institute (ANSI) B 1.20.31976 (R1991). Designated in this catalog by “NPTF.” These threads are designed to seal pressure-tight joints. The threads may incorporate the NPTF (National Standard Pipe Taper Fuel and Oil) or PTF-SAE Short forms. Dry seal threads are used on brass products found within this catalog. Use of a thread sealant is recommended.

Hose threads – Parallel threads for hose couplings and other fittings that are covered by American National Standard ANSI B2.4-1996 (R1974). Threads in this catalog in columns headed “NH” or designated as “NPSH” are threads of full form (as opposed to thin-walled material formed to the desired thread). Pressure-tight joints of hose thread connections are achieved by use of a hose washer placed between coupled surfaces.

NPSM threads – Parallel pipe threads for mechanical joints in hose couplings and other fittings covered by American National Standards Institute (ANSI) B1.20.1

JIC– Joint Industry Committee, a group that has defined standards relating to fittings and other products.

SAE – Society of Automotive Engineers, an organization that writes and distributes technical information and standards.

SAE Tightening Industry Standard – Clamp flare between nut and nose of fitting body by screwing nut on finger-tight. Using a wrench, tighten an additional ¼ turn for a metal-to-metal seal.
