Extreme heat and cold pose no problem for these resilient sealing washers. They won't deform or lose strength at temperatures as low as -400° F and as high as 525° F to handle everything from liquid nitrogen to heating elements. They are also the most chemical-resistant plastic washers we offer to withstand a wide range of acids, bases, solvents, and corrosive cleaners. ePTFE is more flexible than standard PTFE, so these washers compress easily to hold a strong seal. Reuse them a handful of times, as long as the material isn't damaged.

Adhesive-Back Bumpers
 |  |
Style 1 | Style 7 |
Stick these bumpers onto glass and other surfaces that are too fragile or thin for fasteners. Their adhesive sticks to your surface without scratching or discoloring it. From spacers to sound dampeners, they have a wide range of uses. They’re comparable to Bumpon bumpers.

Polyethylene Foam—Use these soft and moisture-resistant bumpers to cushion impact in damp environments, though not outdoors. For a soft bumper that stands up to sunlight and rain, look to silicone foam.
Hardness Rating—The harder the bumper, the better it withstands impact and abrasion over time. The softer the bumper, the more cushioning it provides for objects made of glass, soft metal, and other fragile materials. Bumpers with a medium rating offer a balance of impact resistance and cushioning.

Polyethylene Foam—Use these soft and moisture-resistant bumpers to cushion impact in damp environments, though not outdoors. For a soft bumper that stands up to sunlight and rain, look to silicone foam.
High-Temperature Silicone Foam—The best choice for outdoor use, with a wider temperature range than our other bumpers. They stay soft and flexible in sunlight and temperatures down to -20° F.
Hardness Rating—The harder the bumper, the better it withstands impact and abrasion over time. The softer the bumper, the more cushioning it provides for objects made of glass, soft metal, and other fragile materials. Bumpers with a medium rating offer a balance of impact resistance and cushioning.
