High-Temperature Chemical-Resistant Push-On Seals with Bulb on Side
Similar to standard silicone seals, fluorosilicone rubber seals can be used at high temperatures, but also withstand fuel and oil.

High-Temperature Chemical-Resistant Push-On Seals with Wiper
Made of fluorosilicone rubber, these seals withstand high temperatures like standard silicone without breaking down when exposed to fuel and oil.

High-Temperature Chemical-Resistant Flange-Mount Rope Edge Seals
The PTFE coating on these fiberglass seals is slippery, so they are easier than the other seals to press fit into oven, furnace, and boiler doors. The PTFE resists most acids, alkalies, refrigerants, salts, and grease. The flange is also handy for positioning over uneven gaps.

Ultra High-Temperature Chemical-Resistant Flange-Mount Rope Edge Seals
A ceramic cover makes these seals more chemical resistant than the seals with a silica cover. Seals resist acids (except hydrofluoric and phosphoric), diluted alkalies, most refrigerants, salts, and grease. The flange on these seals slides into a slot that is commonly found on oven, furnace, and boiler doors; it can be positioned to cover large gaps.

Self-Leveling Chemical-Resistant Sealants
Designed to withstand extreme environments, these fluoroelastomer sealants have excellent resistance to sulfuric acid, hydrochloric acid, nitric acid, gasoline, and oil. Thinner than non-sagging sealants, these flow easily into cracks and have a smooth finish.
Elongation and joint expansion/compression tolerance indicate flexibility—the higher the values are, the more joint movement sealants can sustain. These sealants are best suited to joints between similar materials that aren't exposed to wide temperature fluctuation. For high-wear applications, choose a harder sealant for the most abrasion resistance.
Sealants that cannot be sold to the regions listed exceed local regulatory limits on VOCs (volatile organic compounds).

Chemical-Resistant Sealants
Designed to withstand extreme environments, these fluoroelastomer sealants have excellent resistance to harsh chemicals. They’re non-sagging, so they won't drip from vertical and overhead surfaces.
Elongation and joint expansion/compression tolerance indicate flexibility—the higher the values are, the more joint movement sealants can sustain. These sealants are best suited to joints between similar materials that aren't exposed to wide temperature fluctuation.
Viton® fluoroelastomer sealants resist sulfuric acid, hydrochloric acid, nitric acid, gasoline, fuels, and crude oil.
Aflas fluoroelastomer sealants stand up to hydroxides, industrial cleaning fluids, and other pH-basic chemicals in applications where traditional rubber caulk is ineffective.
