High-Temperature Push-On Seals with Bulb on Side
These all-rubber silicone seals can withstand temperatures up to 500° F, plus they resist water and salts. Push them onto a door’s edge to stop wind, dust, and water from entering. They have a hollow bulb for compressibility. The gripping edges are smooth, so they lay flat against the surface.

Molten Metal Splash-Resistant Flange-Mount Rope Edge Seals

A silicone-coated fiberglass cover sheds sparks and molten metal splash while a stainless steel spring core bounces back when pressure is relieved. These seals resist steam, 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 Silicone Sealants

Thinner than non-sagging sealants, these flow easily into cracks and have a smooth finish. Made from silicone, sealants are RTV (room-temperature vulcanizing).
Elongation and joint compression/expansion tolerance indicate flexibility—the higher the values are, the more joint movement sealants can sustain. Sealants that are good for joining dissimilar materials also work well in environments with wide temperature fluctuation.
