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.

Explanation of part numbers – The four digits preceding the dash (-) indicates a series number that identifies the type of product and material used. L- Leaded brass, E- Eco brass B- Bio brass A-Aluminum. The first 2 digits following the dash identify the size of the inside hose diameter used on the fitting, expressed in sixteenths of an inch. The third and fourth digits following the dash identify the size of the thread on the fittings in sixteenths of an inch. Other digits may be used as a suffix to further define the product.
