  • Aluminium construction resists corrosion for long service life
  • Dust plug seals 4-inch cam-and-groove couplings against contamination

ZORO SELECT 4 Inch Aluminum Dust Plug

This ZORO SELECT dust plug seals 4 inch cam and groove couplings. The aluminum body resists corrosion in plumbing and fluid transfer systems. It suits maintenance teams and installers who need a reliable closure for unused ports. The plug handles pressures up to 100 psi in standard service conditions.

Tool Free Installation With Locking Arms

The plug presses into the coupling and secures with built in locking arms. No separate tools or clamps are required for a tight seal. Misalignment during insertion is the most common issue and can prevent the arms from engaging fully. Clean mating faces before fitting to avoid leaks.

Verify Coupling Size And Pressure Rating

Confirm the existing coupling measures 4 inches before ordering. The plug outside diameter is 4 11/16 inches and overall length is 2 7/8 inches. Check that system pressure does not exceed 100 psi. This product contains chemicals listed under California Proposition 65.

Questions about this item

How can I verify the dust plug is sealing correctly after installation?

Pressurise the line to the rated 100 psi and check for leaks around the 4 11/16 in outside diameter; no fluid should escape when the plug is seated.

What comes in the package and is any extra hardware required?

The box contains the aluminum Type DP dust plug only; no locking arm or additional fittings are included.

Which coupling size should I select for a four-inch cam-and-groove hose connection?

Choose the 4 in coupling size version; it matches a 4 in cam-and-groove coupling and has a 2 7/8 in overall length.
