Visbella Gasket Makers


A high temperature RTV silicone designed for bonding and sealing in automotive applications. It forms to any size or shape gasket, and is resistant to both temperature and migration caused by thermal cycling. Can withstand temperature from -80°F up to 650°F (343°C). This product is a one compound RTV silicone sealant that cures completely without excessive odor release. It’s acidic and neutral components solidify into an elastic rubber strip. It’s ideal for timing covers, intake manifolds, exhaust manifolds, cylinder heads, carburetors, and more.
