Rectangular Bellows

Slide these bellows over square rods and shafts. All are molded, which means they're airtight to keep contaminants out. Air venting may be necessary in fast-cycling applications. Screw mount the flange ends to surfaces, or add a mounting flange (sold separately) for stability.

Watertight Sealing Grommets

Rated IP68, these grommets form the tightest seal we offer so no water can leak through the hole. They also seal out dirt and other contaminants, even invisible particles as fine .075 mm. Use them anywhere standing or pooling water is a concern. The flange screws onto the surface for a secure hold.

Horizontal Orientation

These grommets protect 90° bends in cable running along walls, roofs, and other flat surfaces.

Oil-Resistant Buna-N—These resist oil and fuels better than other rubber grommets. Use them on frequently lubricated machinery and oily equipment, such as engines and pumps.

Glass-Filled Nylon Flange—The tough, durable plastic keeps its shape and strength through repeated bumps, kicks, and scrapes.
