The Aluminum Cam & Groove Coupler, Female Half, 3 Inch Female NPT ensures superior reliability in liquid transfer scenarios. Engineered from premium Aluminum A356 or A104, and featuring brass cam levers, this coupler guarantees lasting performance. The use of Buna-N seals and plated steel for pins, rings, and safety clips adds an extra layer of security. Equipped with a practical safety pin feature, the coupler prevents accidental disconnection through cast-in lugs that secure the pins. The coupling mechanism is straightforward: with normal hand pressure, the cam levers can be pressed down to couple, and lifting the cam arms will uncouple the adapter. This model integrates seamlessly with products meeting standard A-A-59326 or DIN 2828. This versatile 3-inch female NPT coupler supports pressure ratings up to 150 PSI for sizes ranging from 1/2" to 4". It is designed exclusively for liquid use and is not compatible with compressed air or steam service.

got a big shop compressor setup running 120 psi. will these hold up for the main air lines
Answer by: Customer Support on Jan 14, 2026, 1:03 PM
Absolutely not. Under no circumstances should you use cam and groove couplings for compressed air or steam service. They are strictly meant for handling liquids.

got a 3" female NPT fitting on my transfer line, this the right coupler to mate up with it?
Answer by: Customer Support on Jul 5, 2025, 1:01 PM
Female NPT on your line means you'll want a female cam and groove coupler on the coupler side, and that's exactly what this one is. The 3-inch female NPT thread connects directly to your existing NPT fitting. Coupling and uncoupling is all hand pressure, press the cam levers down to lock in, lift the arms to release. The cast-in lugs also let you run a safety pin through once it's coupled, so it won't back off on you mid-transfer.
