Ultra-Chemical-Resistant Metal-Detectable PTFE Gaskets for Gasket Tube Fittings
Made from a blend of PTFE and 316 stainless steel, these gaskets stand up to the harsh chemicals and high pressures and temperatures used in sanitary processes. They’ll set off metal detectors if any part of them falls into your line, so you can stop contaminated material from leaving your facility. This helps you comply with Hazard Analysis and Critical Control Point (HACCP) programs. Use these gaskets with high-polish gasket fittings (also called bevel seat fittings) for a more secure seal than quick-clamp sanitary tube fittings.
These gaskets are more durable and last longer than standard PTFE seals. Hot oil, steam, and harsh cleaners won’t warp or deform them, preventing leaks. They’re also chemically inert, so they won’t contaminate your line by absorbing and leaching substances, unless you use molten alkali metal or elemental fluorine. Use them where purity is necessary, such as in food, pharmaceutical, or biotech facilities.
With an extremely smooth interior, these gaskets are easy to clean and leave minimal places for bacteria to grow. To minimize safety risks, they are Animal Derived Ingredient (ADI) free, meaning they’re made without animal products, and are FDA compliant for direct contact with food. Meeting the highest sanitary design standards, these gaskets are 3-A and USP VI certified. They’re also tested to USP 87 standards, which are created by the United States Pharmacopoeia (USP) for safety in biological applications.

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.
Adhesive-back gaskets are wrapped with conductive aluminum foil and stick on with a conductive adhesive. Beryllium copper gaskets withstand repeated compression and decompression over time, so they’re often used with doors that regularly open and close. They’re also known as fingerstock gaskets. Adhesive-back gaskets stick to flat surfaces. Install clip-on gaskets onto surfaces such as circuit board edges or enclosure door frames.
