1/2 in (15 mm) Threaded Coupling, NPT, Galvanised | PCP15G

This AAP threaded coupling is a forged carbon steel fitting with NPT thread and a hot dip galvanised finish. It is supplied in 6 sizes, 1/2 in (15 mm) to 2 in (50 mm).

A coupling joins two male threaded pipes or fittings of the same size. It is threaded inside at both ends. A is its length and B is its outside diameter, as lettered on the AAP drawing.

AAP rates its threaded high pressure fittings at 3000 lb (manufacturer-stated). AAP's pressure and temperature chart for screwed and socket welding fittings lists 3000 lb fittings at 3000 psi (about 20.7 MPa) from -20 to 100 degrees F (-29 to 38 degrees C), reducing to 355 psi (about 2.4 MPa) at 1000 degrees F (538 degrees C). AAP lists ASTM A105 carbon steel forgings among the standards for the range.
