Grommets

Style 1

Protect wire, cable, and cords from holes with sharp or rough edges. Found everywhere from enclosures to machine panels, these grommets keep cords from fraying to extend service life and prevent electrical shorts. With a flexible rubber design, they push easily into holes and reduce vibration in and around sensitive components.

Style 1

Multipurpose SBR Rubber—These durable grommets resist cracking and other signs of wear over long periods. However, they're not for use outdoors or with oil and harsh chemicals.

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.

High-Temperature Silicone Rubber—These keep their shape and strength at higher temperatures than any of our other rubber grommets.

Split Locking Grommets

Snap these grommets around wire, cable, and cords you’ve already installed. Once pushed into place, their wings brace against the hole so the grommet stays put when installed vertically and in vibrating equipment. They fit a range of panel thicknesses, so grommets from one pack will fit a variety of surfaces.

Nylon—Hard and durable, these grommets won't scratch or deform easily. They also withstand exposure to most mild chemicals, greases, fuels, and solvents.

Flex-Grip Locking Grommets

These grommets stay put in vibrating equipment, and occasional impacts won’t bump them out of vertically aligned holes. Expanding wings lock the grommets into place, while flaps in the center cinch closed to prevent wire, cable, and cords from backing out.

Pipe and Tubing Grommets

Protect pipe and tubing from sharp or roughly cut holes. These grommets form a secure seal for routing liquid through metal, plastic, and fiberglass tanks.

Chemical-Resistant Vinyl Plastic—These grommets resist a wide range of acids, bases, solvents, and other harsh chemicals.

Flexible Pipe and Tubing Grommets

These grommets flex to relieve strain and keep a secure hold on moving or misaligned pipe and tubing. They seal the gap between pipe and tubing and a panel so liquid and debris don’t leak through.
