KempCo Specialties is a leading supplier of HHO-related products. One very important part of the Ball jar style generators is the need of a good seal between the jar and the white plastic lid. We spend too much time gluing all of the fittings just to have our HHO disappear through the lack of an efficient seal.

These custom die-cut, re-usable gaskets are designed to fit into the wide mouth Ball jar lids. These are made from 60-shore neoprene rubber, and measure 3-3/8" OD x 2-3/4" ID and are 1/16" thick. These are custom-sized and designed to provide and fit the wide mouth jar lid for that "Perfect Seal"....finally!!

Please Note: These gaskets are not made from food-grade rubber.
