SILA-SEAL™ Professional Grade Silicones are a one-part, non-slumping RTV.  Our red high temperature RTV cures upon contact with moisture in the air to a tough, rubbery solid, providing long-term flexibility and durability. This red high temperature silicone sealant is ideal for heating and air conditioning (HVAC), plumbing, and general applications where high heat occurs.

SILA-SEAL™ Ultra-High Temperature Silicone performs at temperatures from -85°F to 500°F under continuous operating conditions, and intermittent temperatures reaching 600°F.  The high temperature properties make it well suited for sealing and encapsulating heating elements in appliances, aerospace gasketing, moving oven belts, industrial ovens, and bag filters on smoke stacks.

Many uses exist in and around cars, RV’s, boats and small engines. Our high temp red RTV is oxygen sensor safe. Use in any area where high temperatures and vibration are common, but do not allow direct contact with gasoline or diesel fuel.  Other uses include making or replacing paper and cork gaskets in water pumps, timing chain and belt covers, rocker covers, and heat risers.

SILA-SEAL™ Ultra-High Temperature Silicone is ready-to-use.  Our 300ml cartridges fit any standard caulking gun.  See our selection of caulking guns.  The paste-like consistency of this red RTV makes it easy to work with.  Use a spatula or wooden paddle to tool the surface.

SILA-SEAL™ Professional Grade Silicones are perfect for professional and DIY applications requiring a long-term flexible bond. All SILA-SEAL™ Silicones are 100% silicone and contain no fillers.

Supplied in 10.1 fl oz cartridges with a removable nozzle and cap. Packaged 12 cartridges per case.  This product qualifies for free shipping!
