Aluminum Cam & Groove Coupler, Female Half, 3 Inch ID Hose Barb

It’s designed for use with liquids, but it's best to give us a call with the specifics of what you're moving so we can make sure it's a good fit.

For a 3 inch ID hose, ALC-300 is the female cam and groove coupler half with a 3 inch hose barb (hose shank) meant to be installed on the hose end.

For the 3 inch size, you're looking at a 150 PSI pressure rating. That covers all sizes from 1/2 inch up through 4 inch. One hard limit worth knowing up front: cam and groove couplings like this one are not to be used with compressed air or steam under any circumstances. Liquid transfer applications only. If your setup involves air lines, you'd need a different type of fitting altogether.

It’s the female cam and groove coupler half with a 3 inch ID hose barb, so it’s meant to go onto the hose end. The body is aluminum, and it uses brass cam levers with plated steel pins, rings, and a safety clip.
