Polypropylene Cam & Groove Coupler, Female Half, 2 Inch Hose Shank

Cam and groove couplings like this one are strictly rated for liquid service. Compressed air is explicitly off-limits, and so is steam. If your application involves either of those, you'll need a different coupling type altogether. For liquid transfer though, this 2-inch polypropylene coupler handles up to 150 PSI and is built to hold up in demanding conditions.
