3-inch 316 Stainless Male Adapter

This cam-and-groove adapter provides a 3-inch Type F connection with a male NPT thread. The body is 316 stainless steel for corrosion resistance in demanding fluid-handling systems. It carries a maximum working pressure of 125 psi at 70 F. The overall length is 3 15/16 inches and the plug outside diameter is 3 19/32 inches.

Suited for 3-inch NPT piping needing stainless

Installers joining 3-inch hose or pipe to a female NPT port will find the correct thread size and pressure rating here. The design lacks a locking arm, so it is not intended for assemblies that require a cam-lock safety clip. Buyers who need a locking mechanism or a different coupling size should look at other fittings.

316 stainless steel body material

The 316 stainless construction determines chemical compatibility and service life in corrosive environments. This alloy choice is the primary factor in deciding whether the adapter meets the application requirements. The material also carries a California Proposition 65 warning for cancer and reproductive harm.

Questions about this item

Does the 3" Male Adapter x MNPT coupling come with gaskets or clamps, or do I need to buy them separately?

The adapter is supplied as a single 316 stainless steel body; gaskets, cam arms or clamps are not included and must be sourced separately.

When should I select the 316 stainless version instead of a carbon steel alternative for a 3 in NPT connection?

Choose 316 stainless when the media or environment demands higher corrosion resistance than standard carbon steel can provide.

What does the 125 psi rating at 70 °F mean for daily operation of this 3 in Type F adapter?

It indicates the maximum working pressure the coupling can handle at that temperature; system pressure should stay below 125 psi for safe continuous use.
