Water- and Weather-Resistant Foam Rubber Flange-Mount Seals

Softer and more flexible than EPDM rubber seals, these EPDM foam rubber seals will effortlessly conform to uneven surfaces. They resist water, sunlight, and ozone. 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. The foam has closed-cell construction, which resists absorption.Seals have an acrylic adhesive backing good for light duty applications where they won’t be jostled or hit frequently. The adhesive has some resistance to water and chemicals.

EMI/RFI Shielding Gaskets

These gaskets absorb electromagnetic interference (EMI) and radio frequency interference (RFI) to prevent inaccurate signals, flickering displays, and other electrical problems. They compress to fill gaps and complete a grounding path around doors and access panels.

P-shaped gaskets fit around doors and corners. Attach them with the nonconductive adhesive or add bolts or screws through the flange for extra security.

Polyurethane foam gaskets are covered with a conductive nickel/copper braided fabric. A nonconductive adhesive holds them in place. To protect sensitive equipment, they block at least twice as much interference as urethane foam gaskets. They meet UL 94 V-0, so they self-extinguish within 10 seconds if they catch fire and won’t spread the fire by dripping. Cut these gaskets to length with scissors.
