1/4 in (8 mm) Hexagon Plug, NPT, 316 SS | PSTP08
Available
This AAP hexagon plug 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 plug closes a female threaded port or the open end of a fitting. It is threaded on the outside and has a hexagon head for a spanner. A is the width of the hexagon head and B is the length, 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.
