These are the highest flow Camlock couplers that we know of. Made with 304 stainless steel, these come with a proper length barb and work with 1/2" ID silicone tubing. 19/32" ID for maximum flow, which is a larger through put than most Cam Lock fittings. These are really your best value couplers out there. Includes a rubber gasket, however you can add a silicone gasket here.
Please note: These cam locks are NOT compatible with standard 1/2" cam lock fittings from other manufacturers, as these are larger diameter fittings.
