1/2 in (15 mm) 316 Stainless Half Coupling | SSCH15
Available
This AAP half coupling is grade 316 stainless steel with BSP threads. It is supplied in 6 sizes, 1/2 in (15 mm) to 2 in (50 mm).
A half coupling is a short fitting with an internal thread at one end. It is normally welded to a pipe or vessel at the other end to make a threaded outlet. AAP does not describe the end detail, so confirm it with AIMS before you order.
AAP makes its 150 lb stainless steel fittings from grade 316 stainless steel and says 150 lb refers to a maximum working pressure and temperature of 150 psi saturated steam, about 1,034 kPa (manufacturer-stated). AAP gives the grade as 316/316L in its chemical composition table and lists marine, pumping, commercial, chemical and irrigation applications for the range.
