4" Male Adapter Dust Plug

The Banjo 400PL is a 4-inch male adapter dust plug designed to seal couplings on fluid handling systems. Its polypropylene body and EPDM gasket provide chemical compatibility for agricultural and industrial plumbing. The plug installs without a locking arm for quick removal during maintenance. Rated to 75 psi, it protects open ports from contamination.

Suits 4-inch couplings needing temporary closure

This plug fits Banjo couplings with a 4-inch nominal size and a 4 23/32 inch outside diameter. It serves operators who require a simple, pressure-rated seal for storage or transport. Systems requiring a locking arm for vibration security or a tethered cap for frequent access should consider alternative configurations.

75 psi pressure rating defines the limit

The maximum working pressure of 75 psi determines whether this plug matches the system requirements. Exceeding this rating risks seal failure and fluid loss. Verify the operating pressure of the circuit before installation to ensure the polypropylene body and EPDM gasket remain within safe limits.

Questions about this item

Will the EPDM gasket on the 400PL need periodic replacement?

The EPDM gasket resists water and common chemicals, but should be inspected regularly and replaced if it shows cracking or loss of elasticity.

At what pressure does the 400PL dust plug reach its rated limit?

The plug is rated for 75 psi; sustained pressure above that level can cause leakage or deformation.

Does the polypropylene body of the 400PL get hot or transmit vibration when fluid flows all day?

Polypropylene stays cool to the touch and dampens vibration, so the plug runs quietly without noticeable heat buildup during continuous flow.
