Gasket Shown with Flat-Surface Pipe Flange

Gasket Shown with Raised-Surface Pipe Flange

Corrugated

Made of 110 copper, these gaskets handle steam applications up to 600° F. They are electrically conductive and resist water, Freon, and fuel oil. 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 are compatible with low-pressure pipe flanges; all gasket specifications are sized to meet ANSI standards.

Corrugated gaskets conform to rough and uneven surfaces when put under low pressure for a tight seal.

Gasket Tape

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.

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.

Sheets work well between two flat surfaces.

Half-round gaskets work well in grooves. Use a gasket slightly thicker than the depth of the groove; it will compress to fill the gap.

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 94 V-0, 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.

Food Industry Abrasion-Resistant Polyurethane Rubber Sheets and Strips

Use in food-processing environments for cutting surfaces, liners, and other high-wear applications. These sheets and strips are FDA compliant for direct contact with food.

Metal- and X-ray detectable sheets and strips contain metal and chemical additives that will set off metal detectors and show up on X-ray machines if they fall into your food lines. The metal additive also makes it easy for magnetic traps to catch any broken pieces that may fall into a line. Use these sheets and strips to help you comply with Hazard Analysis and Critical Control Point (HACCP) programs. They do not contain Bisphenol A (BPA), which is a chemical that can contaminate process lines.

Magnetic Wear Strips

Easily attach, move, and replace these magnetic wear strips on metal surfaces to minimize friction—simply press them on and peel them off as needed. Often found on conveyor systems and chutes, use these strips where friction between two parts or materials is wearing down equipment to extend equipment life. All of these strips have an extra-hard rating to withstand high levels of impact. They are flexible enough to bend around a curve. They're also nonmarking.

Silicone-filled UHMW strips are more slippery than the standard UHMW strips. Objects with adhesives and labels on them will not stick to them to prevent backups on conveyors and chutes.
