Sealing Grommets

Split Sealing Grommets

The two‐piece design makes it easy to install and seal these grommets around wire, cable, and cords that are already in place. Use them to keep out dust, debris, and moisture.

Create-Your-Own Split Sealing Grommets

Cut the center of these grommets with a utility knife to create custom IDs. The two‐piece design makes it easy to install and seal these grommets around wire, cable, and cords that are already in place. Use them to keep out dust, debris, and moisture.

Liquid-Tight Sealing Grommets

Rated IP68, these grommets form liquid-tight seals around wire, cable, and cords to protect them against dust as well as submersion in a maximum of one meter of water.

Sealing Grommets

Create a tight seal around wire, cable, and cords with these grommets to keep out dust, debris, and moisture.

Shrink-to-Fit Sealing Grommets

Apply heat and these grommets shrink around wire, cable, and cords to keep out dust, debris, and moisture.

Grommets

Push these flexible grommets into place to protect wire, cable, and cords by turning rough-edged and uneven holes into smooth, insulated holes. Commonly used in metal panels, they also damp vibration.

Grommet Assortments

Keep grommets of various sizes on hand to solve whatever problems arise.

Cut-to-Size Grommets

Cut the thin layer of rubber in the center of these grommets to create custom IDs to securely hold and protect wire, cable, and cords. Push these grommets into place. They turn rough-edged and uneven holes into smooth, insulated holes. Commonly used in metal panels, they also damp vibration. Also known as webbed grommets.

Expandable Grommets

The center hole has flaps that flex to hold and protect various sizes of wire, cable, and cords while keeping out dust and debris. Push these grommets into place. They turn rough-edged and uneven holes into smooth, insulated holes.

High-Temperature Grommets

These flexible grommets withstand temperatures of 450° F or greater, which is approximately twice as high as our standard grommets. Push them into place to protect wire, cable, and cords by turning rough-edged and uneven holes into smooth, insulated holes. Commonly used in metal panels, they also damp vibration.

Expandable Locking Grommets

The center hole has flaps that flex to hold and protect various sizes of wire, cable, and cords while keeping out dust and debris. Snap these grommets into place and their wings expand against the sides of the hole to lock them in position. Use them to turn rough-edged and uneven holes into smooth holes.

Split Grommets

A slit in the side of these grommets allows you to install them around wire, cable, and cords that are already in place. They snap into the hole and their wings hold them tight. Use them to turn rough-edged and uneven holes into smooth, insulated holes.

Locking Grommets
