Push-On Seals with Glass Locking Slot

Seal stationary windows into place with these EPDM seals. To install, lubricate the seal with soap and water, then push the bottom of the seal around the edge of the window opening. Insert glass into the top opening of the seal and press the attached insert into the seal to lock the glass in place. EPDM resists water, sunlight, and ozone.

Water- and Weather-Resistant Hollow Foam Rubber Surface-Mount Seals
These EPDM foam rubber seals have hollow construction for more compressibility than solid seals. They resist water, sunlight, and ozone. They’re softer and more flexible than EPDM rubber seals and will effortlessly conform to uneven surfaces to shield against dust, noise, and vibration. The foam has closed-cell construction, which resists absorption.
Seals with an acrylic adhesive backing are good for light duty applications where they won’t be jostled or hit frequently. The adhesive has some resistance to water and chemicals.
Seals with a 3M acrylic adhesive backing are more resistant to peeling and shearing than seals with an acrylic adhesive backing. Use them when you need extra sticking strength to resist repeated impact, such as on a door or door frame. They create a permanent moisture barrier and airtight seal between the seal and the surface it’s stuck to, but only if you let the bond cure for 72 hours.
Water- and Weather-Resistant Hollow Rubber Surface-Mount Seals
Hollow construction makes these seals more compressible than solid rubber seals. Made of EPDM rubber, they resist water, sunlight, ozone, and salts. They are firmer and more durable than EPDM foam rubber. Attach them directly to a door’s surface to shield against dust, noise, and vibration.
Water-Resistant Hollow Rubber Surface-Mount Seals

Made of vinyl rubber, these seals resist water, salts, and detergents. Hollow construction provides compressibility. Attach them directly to the door’s surface to shield against dust, noise, and vibration.
High-Temperature Hollow Rubber Flange-Mount Seals
Hollow construction makes these silicone rubber seals more compressible than solid seals. They resist heat, water, and salts. They’re firmer and more durable than silicone foam rubber. These seals have a flange that can be positioned along a door’s edge to cover gaps and block dust, noise, and vibration.
High-Temperature Hollow Foam Rubber Flange-Mount Seals
These silicone foam rubber seals are hollow for better compressibility than solid seals. They resist heat, water, and salts. They’re softer and more flexible than silicone rubber seals and will effortlessly conform to uneven surfaces. These seals have a flange that can be positioned along a door’s edge to cover gaps and block dust, noise, and vibration. The foam has closed-cell construction, which resists absorption.
Water- and Weather-Resistant Hollow Rubber Flange-Mount Seals
Firmer and more durable than EPDM foam rubber seals, these seals are made of EPDM rubber. They resist water, sunlight, ozone, and salts. They have hollow construction for compressibility and a flange that can be positioned along a door’s edge to cover gaps and block dust, noise, and vibration.
Chemical-Resistant Flange-Mount Seals
Made of Viton® fluoroelastomer rubber, these seals stand up to fuels and aggressive chemicals, such as petroleum oil, hydrofluoric acid, and propyl alcohol. They have hollow construction for compressibility and a flange that can be positioned along a door’s edge to cover gaps and block dust, noise, and vibration.
Oil-Resistant Flange-Mount Seals

Made of Buna-N rubber, these seals resist oil, grease, salts, water, steam, and most detergents. They have a hollow construction, so they’re more compressible than solid seals.
High-Temperature Ultra-Conformable Rope Edge Seals

These loosely knitted fiberglass seals are more flexible, compressible, and conformable than High-Temperature Rope Edge Seals. The looser construction also makes them more likely to absorb liquids. Push them into the groove that’s commonly built into oven doors, furnaces, and tanks. They resist bleach, solvents, and most acids (do not use with hydrofluoric acid, hot phosphoric acid, and wet hydrogen chloride).
Square-Profile Ultra High-Temperature Rope Edge Seals

The flat edges on these square-profile seals provide more sealing surface than round-profile seals. They’re made of 98% silica for excellent temperature resistance. They’re flexible and will conform to uneven surfaces. Push them into the groove that’s commonly built into oven doors, furnaces, and tanks. They resist water, salts, and diluted acids.
High-Temperature Flange-Mount Rope Edge Seals

In addition to high temperatures, these seals have a fiberglass cover and core that resists most refrigerants, salts, and grease. They’re flexible and compressible, and are often used as caulking and for filling expansion joints. 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.
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.
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.
Multipurpose Neoprene Foam Sheets and Strips
In addition to having good resistance to water, sunlight, and oxidation, these neoprene foam sheets and strips resist swelling when they come into contact with oil.
Closed-cell foam restricts water, air, and gases from being absorbed.

Fabric-Reinforced High-Temperature Silicone Foam Strips
One layer of fiberglass fabric is sandwiched between layers of silicone foam giving these strips strength to handle high-stress applications, such as gasketing. Silicone will maintain its flexibility across a wide range of temperatures. This foam has closed-cell construction, which restricts water, air, and gases from being absorbed. These strips have a crisscross texture that provides a nonslip gripping surface.
