    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.

    Half-round gaskets work well in grooves. Use a gasket slightly thicker than the depth of the groove; it will compress to fill the gap.
    Polyurethane Foam—Polyurethane foam gaskets are covered with either a conductive nickel/copper braided fabric or conductive aluminum foil. A nonconductive adhesive holds them in place. To protect sensitive equipment, they block at least twice as much interference as urethane foam gaskets. Cut these gaskets to length with scissors.
    Adhesive Backing—Adhesive-back gaskets stick to flat surfaces.
    UL 94 V-0—Gaskets that meet UL 94 V-0 self-extinguish within 10 seconds if they catch fire and won’t spread the fire by dripping.

    Protect O-rings in equipment operating at pressures up to 4,300 psi. These backup rings support O-rings to extend their life and prevent them from deforming under pressure, which can cause pressure loss. Made of PTFE, they’re rigid enough to hold their shape under load, yet slippery enough to reduce friction in moving parts. They also resist a wide range of chemicals. Often used in pipeline valves and chemical processing equipment, they have a split ring design to simplify installation. All have a shelf life, cure date, and a traceable lot number printed on the bag.
