3-Inch Coupler Dust Cap

The USA INDUSTRIALS 304 stainless steel dust cap protects 3-inch cam-and-groove couplers from contamination. Its nitrile gasket seals the socket against dust and moisture during storage or transport. The socket inside diameter measures 3 5/8 inches for a precise fit on compatible fittings. The natural metal finish resists corrosion in industrial environments.

Suited for fluid-line maintenance.

Maintenance teams use this cap to keep idle couplers clean on water, chemical or petroleum lines rated to 200 psi. The design lacks locking arms, so it cannot secure a pressurised connection. Operators needing a sealed, load-bearing closure should select a fitting with a locking mechanism.

304 stainless steel body with nitrile gasket

Grade 304 stainless steel provides broad chemical compatibility for the cap body. The nitrile gasket handles common oils, fuels and water-based fluids within the 200 psi rating. Verify that both materials suit the specific media and temperature range before installation.

Questions about this item

Will the nitrile gasket on the 304 stainless steel dust cap need periodic replacement?

The nitrile gasket can degrade over time and should be inspected regularly; replace it when it shows cracking or loss of elasticity to maintain a proper seal.

What pressure limit applies during continuous service for the 3 inch coupler dust cap?

The fitting is rated for 200 psi, so sustained operation must stay at or below that pressure.

How much heat does the stainless steel body generate when the dust cap is under constant 200 psi flow?

The 304 stainless steel body does not generate heat itself; any temperature rise comes from the fluid passing through the 76.5 mm length.
