High-Temperature Metallic Pipe Gaskets
a Flat-Surface
Pipe Flange
Also known as spiral-wound gaskets, these have a 1/8” thick carbon steel outer ring and a 304 stainless steel sealing element with a graphite-based filler. The metal construction provides structural strength. These gaskets can be used with both flat-surface and raised-surfaces pipe flanges; they fit the surface inside the bolt holes and do not interfere with the bolt connection.
Gaskets for ANSI class flanges are sized so all gasket specifications meet ANSI standards. Gaskets for ANSI Class 1500 flanges are compatible with extreme-pressure pipe flanges.
Gaskets with an inner ring prevent flange erosion.

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.

High-Temperature Silicone Gaskets with Perforations for Quick-Clamp Tube Fittings
Use these perforated gaskets to filter liquids and dry materials, as well as create a tight seal in quick-clamp stainless steel sanitary tube fittings. Made of silicone, they handle temperatures up to 450° F, so they’re good for heated ingredients and clean-in-place (CIP) processes. However, oils will degrade them. Their perforated plate is 316 stainless steel to withstand washdowns with harsh cleaners and sanitizers. All of these gaskets are 3-A certified to meet sanitary design standards and FDA compliant for direct contact with food. USP Class VI, they’ve been tested to the highest standards to reduce the risk of leaching into biological samples. They also meet ASME BPE, which is a design standard for bioprocessing equipment that helps ensure purity and safety.
