This is a USA FDA approved Camlock Flat Gasket. It is compatible with all 1/2" Female Style B, C, D & Dust Cap. Listed by the National Sanitation Foundation. (NSF 51).Note Regarding "Fit":Some may find that occasionally the male and female camlocks can be a little more difficult to connect than usual from time to time. Specifically, that it can take some more effort to close the locking cam arms. In many cases this can be attributed to manufacturing tolerances from lot to lot. Something as simple as the thickness of the gasket can affect how much pressure is needed to push on the cam arms. Specifications: Made out of Food Grade Silicone 1" Outer Diameter 5/8" Inner Diameter If you find your mating pair to be difficult to close, consider the following tips before requesting a replacement or return: Be sure to close both cam arms simultaneously, not one at a time While closing the cam arms, push the two fittings together to compress the gasket slightly A small amount of lubricant on the cams where the grooves contact helps (anything food grade such as vasoline to keg lube will work) Break in the gaskets by leaving the mating pair connected for a few days, making it easier to reconnect in the future
