High-Temperature Steam-Resistant Metallic Pipe Gaskets
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.

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 either a conductive nickel/copper braided fabric or conductive aluminum foil. A nonconductive adhesive holds them in place. To protect sensitive equipment, they block at least twice as much interference as urethane foam gaskets. Cut these gaskets to length with scissors.
Gaskets that meet UL 94 V-0 self-extinguish within 10 seconds if they catch fire and won’t spread the fire by dripping.

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.
