Cast Steel Universal Air Hose Coupling, 1 Inch Female NPT

This coupling has a 1 inch female NPT connection, so it should work with any air hose that has a compatible male NPT fitting. Keep in mind the performance will vary a bit depending on your hose size, how you clamp it, and how well you install everything.

With a 1 inch female NPT connection, it threads onto a matching 1 inch male NPT fitting.

Keep it away from steam service entirely. That's a hard no for this coupling regardless of proximity or exposure level. For temperature, it's rated to handle anywhere from -20°F up to 160°F using the standard rubber washer, so general shop heat near steam lines isn't automatically a dealbreaker, but direct steam contact or steam service use is not something it's built for.
