Ultra-Chemical-Resistant Metal-Detectable PTFE Gaskets
for Extra-Support Quick-Clamp Sanitary Tube Fittings
Made from a blend of PTFE and 316 stainless steel, these gaskets hold up to the harsh chemicals, high pressures, and high temperatures used in sanitary processes. They’ll set off metal detectors if they fall into your line, so you can prevent contaminated material from leaving your facility. This helps you comply with Hazard Analysis and Critical Control Point (HACCP) programs. Use them with extra-support quick-clamp sanitary tube fittings (also known as I-line fittings) to create a tight, leak-proof seal.
These gaskets are more durable and last longer than standard PTFE seals. To protect against leaks, they won’t warp or deform, even in steam or hot oil, and they won’t degrade from harsh cleaners. They’re also chemically inert, so they won’t contaminate your line by absorbing and leaching substances (except when used with molten alkali metal or elemental fluorine). They’re often used in applications where purity is essential, such as in food, pharmaceutical, or biotech facilities.
The interior of these gaskets is extremely smooth, so they’re easy to clean and bacteria has nowhere to grow. They’re Animal Derived Ingredient (ADI) free, meaning they are made without animal products, and they’re FDA compliant for direct contact with food. Made to the highest standards of sanitary design, 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.

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.
