If a piece wears off, fragments as small as 1 mm can be picked up by a metal-detection system to prevent contamination of your process line. These gaskets are made from a blend of PTFE and stainless steel, which is chemically inert (except to molten alkali metal and elemental fluorine). The construction also allows them to maintain their strength in steam and hot oil applications.

Ultra-Chemical-Resistant Metal-Detectable PTFE Gaskets for Extra-Support Quick-Clamp Sanitary Tube Fittings

Image of Product. Front orientation. Contains Border, MultipleImages. Tube Fitting Gaskets. 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 PTFE Gaskets with Perforations for Quick-Clamp Tube Fittings

Image of Product. Front orientation. CrossSection view. Contains Inset, MultipleImages. Tube Fitting Gaskets. Ultra-Chemical-Resistant PTFE Gaskets with Perforations for Quick-Clamp Tube Fittings.

These chemical-resistant gaskets have a perforated plate that filters, separates, and strains liquids or dry materials in your line. Made of 316 stainless steel, the plate won’t corrode from frequent washdowns with harsh cleaners. Gaskets are made of PTFE for excellent resistance to detergents, hydraulic fluid, and salts, and good resistance to most acids and alkalis. They create tight seals in quick-clamp sanitary tube fittings. These gaskets are 3-A certified for sanitary design and are FDA compliant for direct contact with food. They meet ASME BPE purity and safety standards, and are rated USP Class VI as plastic that won’t leach into biological samples.

Oil-Resistant Buna-N Gaskets for John Perry Gasket Fittings

Create a tight seal when connecting John Perry fittings. Made of Buna-N, these gaskets resist oil and water. They’re FDA compliant for direct contact with food and are often used in food and dairy plants. These gaskets have an extremely smooth interior, so they’re easy to clean and there’s little room for bacteria to grow.

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.
