Very soft and conformable, this expanded PTFE gasket tape compresses into an extremely thin profile. Use it to create a leak-resistant seal in tight-tolerance applications, such as on precision machinery. This tape is chemically inert, except to molten alkali metal and elemental fluorine.

Gasket tape that is made with FDA-listed material is for use with food and beverage.

These gaskets absorb electromagnetic interference (EMI) and radio frequency interference (RFI) to prevent inaccurate signals, flickering displays, and other electrical problems. Made of foam or rubber combined with conductive material, they compress to fill gaps and complete a grounding path around doors and access panels.

Sheets work well between two flat surfaces.

Urethane foam gaskets block EMI and RFI in most applications. Plain-back gaskets are made with conductive silver wire. They meet UL 94HF1, which means they stop burning within two seconds if they catch on fire and won’t spread the fire by dripping.

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 94V0, 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.
