Oil-Resistant Buna-N Foam Sheets

Color: Black
Temperature Range: -40° to 200° F
Cell Type: Closed
For Use Outdoors: Yes
Density: 14 lbs./cu. ft.
Pressure to Compress 25%: 4 psi (Ultra Soft)
Tensile Strength Rating: Good
Oil-Resistance Rating: Excellent

Made of Buna-N foam, these sheets offer excellent oil resistance. They also resist fuel and solvents. Buna-N is also known as nitrile, NBR, and acrylonitrile butadiene. Foam has closed-cell construction, which restricts water, air, and gases from being absorbed.

Oil-Resistant Push-On Seals with Bulb on Side

In addition to oil, these seals resist grease, salts, water, steam, and most detergents. Push them onto a door’s edge to stop wind, dust, and water from entering. They have a hollow Buna-N foam rubber bulb for compressibility. The foam has closed-cell construction, which resists absorption. The gripping edges have fingers to provide a strong hold.

Oil-Resistant Rubber Push-On Seals with Bulb on Top

The Buna-N foam rubber bulb on these seals resists oil, grease, salts, water, steam, and most detergents. The bulb is hollow for compressibility and the foam has closed-cell construction, which resists absorption. Push seals onto a door’s edge to stop wind, dust, and water from entering. The gripping edges have fingers for a strong hold.

Split Grips

Use the hook-and-loop closure to secure these grips anywhere on a handle—even those where the ends are not accessible such as on carts, drawers, and machine doors. The loop strip has an adhesive back so you can attach it to the handle and then wrap the hook strip around it.
