LIQUID GASKET THREEBOND BLACK 100GLiquid Gaskets are liquid sealants used for sealing inner fluids by applying them to the joint surfaces of various flanges, screws etc. Highly reliable sealing is achieved by filling in and adhering to the minute clearance on the joint surface. As they are a liquid when applied, so metal joint surfaces touch each other, and there is almost no decrease in surface pressure due to vibration. Therefore, they are durable and have excellent sealability.
