Aluminum Cam & Groove Coupler, Female Half, 3/4 Inch Male NPT

Cast-in lugs on the female coupler body let you run a safety pin through once the adapter is locked in place. The pin physically blocks the cam levers from lifting, so an accidental bump or snag won't release the connection. You'd have to pull the pin out before you can uncouple it. Good feature to have anywhere there's foot traffic or equipment moving around near your lines.

Interchangeability is a key feature; this coupler conforms to A-A-59326 and DIN 2828 standards, meaning it should be compatible with other products made to those specs. Note that there isn't a standard for 1/2” and 8” sizes.

For a threaded connection, this one fits a 3/4 inch male NPT port because the coupler end is a 3/4 inch male NPT thread. The other side is the female cam and groove half that accepts a matching cam and groove adapter.
