Pipe Thread Gages

About

Pipe thread gages verify the taper, size, and hand-tight engagement of threaded pipe, fittings, and couplings so sealed joints assemble correctly every time. WESTport manufactures the full range of pipe thread gaging in-house and certifies every gage against NIST-traceable masters. This collection covers the pipe thread families we stock and build to order: NPT taper pipe (L1) plug and ring gages for functional size and hand-tight engagement, per ANSI/ASME B1.20.1. NPTF (Dryseal) plug and ring gages — L1, L3, and 6-step crest/root checks — per ANSI/ASME B1.20.5. ANPT aeronautical taper pipe plug and ring gages per SAE AS71051, for sealed thread joints in aerospace components. Straight pipe (NPSC/NPSM) plug and ring gages for straight internal and external pipe threads. GO and NO GO members, class X tolerance, each inspected in an environmentally controlled ISO/IEC 17025 accredited laboratory.
