Silverhook RTV Instant Gasket is a general-purpose silicone rubber sealant that seals, insulates and waterproofs, replacing conventional gaskets in an instant. It can be used as an excellent general-purpose adhesive as it bonds metal, plastic, rubber, glass and many other materials.
Its special formulation allows it to withstand temperatures from -62°C to +260°C and intermittent use to +315°C. It rapidly forms a skin but does not harden or crack and will resist all lubricating, coolant and transmission fluids.
It replaces conventional gaskets and is ideal for automotive, marine and gardening equipment. Excellent for use on water pumps, transmission pans, timing gear covers exhaust manifolds and differential covers etc. It also insulates electrical parts and makes a perfect gasket for solenoid and relay covers etc.
