1/4 in (8 mm) Threaded Coupling, NPT, 316 SS | PSTCP08
Available
This AAP threaded coupling is a 316/316L stainless steel forged fitting with NPT thread. It is supplied in 8 sizes, 1/4 in (8 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 stainless steel high pressure fittings at 3000 lb (manufacturer-stated) and lists them as 316/316L stainless steel to ASTM A182. AAP does not say which material its pressure and temperature chart covers, so AIMS does not quote it for stainless steel. Confirm the pressure rating at your operating temperature with AIMS before you order.
