## Description

500°F heat resistant silicone sealant forms a tough rubbery adhesive seal. Adheres to most materials.

Review: Rutland 500°F RTV High Heat Silicone Sealant – Clear and Tough for Heat - I grabbed this Rutland 10.3 oz clear silicone cartridge to seal some gaps around my wood stove’s vent pipe, and it’s been a reliable performer. Rated for up to 500°F (intermittent) or 450°F (continuous), it’s built for high-heat spots like fireplaces, ovens, or grills. The clear finish is a huge plus—blends right into the stainless steel pipe without looking gaudy like red or black sealants might. Applying it with a caulk gun was smooth; the consistency is thick but workable, and it didn’t sag even on vertical seams. After curing for 24 hours (as recommended), it formed a flexible, rubbery seal that’s held up to a few weeks of daily fires—no cracks, no smoke leaks, and no sign of heat damage. The adhesion is strong too; it stuck to both the metal pipe and the surrounding brick without peeling. I also like that it’s made in the USA—feels good supporting that. The 10.3 oz size gave me plenty to work with—covered about 20 feet of 1/4-inch bead with some left over. A couple cons: the vinegar-like smell during application was intense, so I’d suggest good ventilation or a mask. Also, it’s messy if you’re not careful—wearing gloves saved me from a sticky cleanup. Compared to a cheaper RTV silicone I’ve tried, this one’s heat resistance and flexibility are noticeably better, though it costs a bit more. For high-temp sealing jobs, this stuff shines. It’s versatile (glass, metal, wood, etc.), durable, and discreet with that clear look. I’d give it 4.5 stars—half off for the smell, but rounded up to 5 for how well it works. Great for stoves or any heat-exposed fix—just prep your space!
Review: Adhered Brick To Fireplace - I used this to adhere brick to the metal area on my gas fireplace since it gets really hot. Worked great and is holding up. It does have a very strong smell when using though.

## Questions & Answers

**Q: I am looking for a product that will still have that rubbery traction but able to withstand temperature. I am trying to be able to attachan object to a piece of metal with magnets so that it can be attached and detached. I need the surface to keep it from slipping I.E. silicone.**
A: Google "Curie Temperature" before using magnets on any type of homemade smoker,grill or stove repair. Because you chose this high heat sealant, I assume you'll be cooking or at least burning something. The sealant may hold the magnet to the desired object, but at a certain temperature, the magnet itself will fail.

**Q: would this work to repair a wooden boat? Is it waterproof?**
A: I believe it probably would, not sure you would need 500 degree temperatures though. you can buy a regular black silicone at the auto parts store. regular black silicone should work great on a wooden boat.

**Q: linear crack small  on car radiator**
A: This would not work. Car radiators hold water under pressure as it heats up. Radiator caps generally are rated at 15 pound per square inch before they realese pressure.

**Q: Does it smell? After or before?**
A: It smells like silicone sealer for a while then it fades after a day or so to nothing.
