Visit our site http://truelok.us/ for more information on Face Seal Gaskets and Nuts.Our highest concerns are that top quality specs need to be measurable and constant and that item functions should meet our customer's requirements. The Face Seal Fittings has the capacity to secure onto television with a 'double bite' attribute. Each ring attacks in to boob tube providing 2 different closing areas. This style of fitting does so without sending torque or twisting boob tube making certain that television does not become stressed.
