Stainless-Steel Dust Plug for 1-1/2" Cam-and-Groove

This 304 stainless-steel dust plug fits a 1-1/2 inch cam-and-groove coupling and protects the adapter face when the line is disconnected. It is built for industrial fluid-handling systems that require a corrosion-resistant seal.

Pressure Limit and Sealing Scope

The plug is rated for 250 psi and matches the coupling size exactly, so it cannot be used on larger or smaller fittings. It has no locking arm, meaning it relies on the cam levers of the mating coupler for retention.

Verify Coupling Size and Material Compatibility

Confirm that your existing coupler is a 1-1/2 inch DP type before ordering. Ensure the process fluid is compatible with 304 stainless steel and that the 250 psi rating meets the system's maximum operating pressure.

Questions about this item

Should I choose the 1-1/2 inch dust plug or a different coupling size?

This dust plug is made for a 1-1/2 inch coupling size. If your cam and groove fitting uses that size, this is the correct plug.

What does the 250 psi rating mean when the plug is installed?

The 250 psi rating shows the maximum working pressure the 304 stainless steel plug can handle when fitted to a matching coupling.

Which cam and groove standard does the DP type follow and what does it limit?

The DP type follows standard cam and groove dimensions for 1-1/2 inch couplings, limiting use to fittings with the same size and pressure class.
