Red Ultra-High Temperature Silicone (600°) – Professional Grade Sealant | Case of 12


100% silicone sealant formulated to perform at temperatures ranging from -65°F to 600°F


SILA-SEAL™ Professional Grade Silicones can help make your home more energy efficient.  Close up those gaps around your heater, heating vents, and hot water heater. This is a 100% pure silicone sealant and contains no fillers like our competition.  A one-part, non-slumping RTV, this red silicone cures upon contact with moisture in the air. Mostly used for general purpose sealing, SILA-SEAL™ Red Ultra-High Temperature cures to a tough, rubbery solid, and provides long-term flexibility and durability.  Ideal for heating and air conditioning (HVAC), plumbing, construction, and other general purpose applications where high heat can occur.

Hey car guys, check this out!  Don’t settle for those high-priced automotive gasket makers in the cheese wiz cans that run out of pressure after one or two uses.  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.  Many uses exist in and around cars, RV’s, boats and small engines.

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.

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 or without a removable nozzle and cap.  12 cartridges per case.
