High Temperature Silicone Sealant 1500°C Black | Heavy Duty Heat Resistant Fire Cement & Flue Sealer | For Wood Burner Stoves, Chimneys, Ovens & Fireplace Repair | Professional Grade Cartridge
DIYUK
Why we love it
Extreme heat resistance guarantees durability.
Permanent stone-hard seal prevents leaks.
Superior adhesion on various surfaces.
Main Highlights
EXTREME HEAT RESISTANCE UP TO 1500°C: Engineered for the harshest environments, this silicate-based formula withstands direct flame and continuous temperatures of 1500°C (2732°F). Far superior to standard red automotive silicones (max 300°C), it is the ultimate solution for sealing joints in wood-burning stoves, multi-fuel fires, pizza ovens, and industrial flues.
PERMANENT "STONE-HARD" VITRIFICATION: Unlike rubbery gaskets that degrade, this sealant cures to a rigid, rock-hard ceramic mass. Through a unique vitrification process, it bonds physically with masonry and metal to form a hermetic, smoke-tight seal that prevents dangerous carbon monoxide leaks and maintains flue draught efficiency. Note: Designed for static joints; does not remain flexible.
SUPERIOR ADHESION TO MULTIPLE SURFACES: formulated to bond aggressively to cast iron, mild steel, stainless steel, firebrick, concrete, stone, and clay. Perfect for sealing flue spigots, fixing loose firebricks, bonding ceramic glass tape, and sealing register plates.
PROFESSIONAL GREY/CHARCOAL FINISH: The thixotropic (non-slump) paste applies black and cures to a discreet, matte dark grey/charcoal that blends seamlessly with cast iron stoves and flue pipes. This ensures invisible repairs that maintain the aesthetic of your hearth.

flintronic
15% Off
Limited time deal
Why we love it
Excellent adhesion and durability.
Quick, mildew-proof, waterproof seal.
Wide range of applications.
Main Highlights
🔔【EXCELLENT MATERIAL】RTV sealant is made with a non-corrosive formula, designed for excellent adhesion and long-term durability on oily surfaces, ideal for a variety of applications to prevent leaks and mold formation. The sealant is resistant to water, oil, gas and antifreeze, and can withstand temperatures ranging from -62°C to 343°C.
🔔【QUICK SEAL】RTV sealant for high-strength connections hardens in a short time when exposed to air, and the silicone material forms a strong, mildew-proof and waterproof seal once it dries. It will not shrink, drip, seep, leak or crack, and is resistant to aging and weathering, and will not affect the operation of the sensor.
🔔【RELIABLE FUNCTION】Unlike traditional sealing methods such as cork, paper, rubber seals, etc., our RTV sealant can quickly cure to form an instant gasket when used correctly, which can effectively prevent water, oil and gas leaks. It can be used on all parts at the same time, and is waterproof and high temperature resistant. It is small and convenient, does not take up space, and is easy to carry with you.
🔔【PERFECT APPLICATION】This This high temperature sealant is widely suitable for various surfaces and is easy to use. It can be widely used on metal materials such as stainless steel, aluminum and brass, and is also suitable for glass, wooden items and other places where sealing is required. When the product is exposed to air for a period of time, it will solidify and form a solid waterproof seal on the surface of the object.
🔔【WIDE APPLICATION】The sealant is widely used in various cars, motorcycles, various metals, oil pans, exhaust manifolds, water pumps, timing covers, differential covers, valve covers, drive housings and oven doors, etc. Any place you can think of that needs to be sealed. Make a reliable "molded" seal that prevents cracking, shrinking and migration, ensuring a long-lasting, waterproof and mildew-proof seal.
