Stainless Steel Cam & Groove Adapter, Male Half, 1 Inch Male NPT

For the 1 inch size, you're working with a 150 PSI rating, same as anything else in the half-inch through 4 inch range. That said, compressed air is a hard no with these cam and groove couplings. Steam's off the table too. These are built strictly for liquid service, so keep that in mind before putting one in a pneumatic line.

The 316 stainless steel should work well with a variety of liquids and hold up in demanding environments.

For a 1 inch male NPT threaded connection, this adapter matches that size and thread style. It is the male half cam and groove adapter with a 1 inch male NPT end.
