Harris Silicone Sealant Tube Grey Original High Temp Up to 550°F Automotive Gasket Maker

Description

Harris Silicone Sealant Tube Grey (High Temp Up to 550°F) is an automotive gasket maker and high-temperature elastomeric sealant formulated for tough mechanical sealing applications. Manufactured by Harris Silicones & Gasket (Pvt) Ltd., this flexible, room-temperature vulcanizing (RTV) silicone adhesive forms a durable, rubber-like joint that withstands extreme thermal stress up to 550°F (287°C). It provides resistance against engine oil, transmission fluid, water, coolant, vibration, and thermal expansion, preventing fluid leaks and pressure loss. The squeeze tube format with an included applicator tip allows controlled, accurate bead dispensing directly onto metal sumps, valve covers, water pumps, gearboxes, and pipe joints. It adheres firmly to aluminum, cast iron, steel, glass, ceramics, and coated surfaces without shrinking, hardening, or cracking over time. Suitable for both indoor and outdoor automotive, mechanical, and industrial applications. Clean mating surfaces thoroughly of grease, oil, and old gasket remnants prior to application. Allow adequate cure time according to standard high-temperature RTV gasket installation practices.
