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. All of these grommets have a medium hardness rating to offer a balance of cushioning and impact resistance.
SBR grommets have good abrasion resistance. They are not for use outdoors.
Buna-N grommets withstand a wider range of temperatures than other grommets and resist abrasion, oil, and grease. They are not for use outdoors.
Grommets that meet MIL-G-3036 resist hot petroleum-based oil and coolant.
Grommets that meet MS-35489 and AN931 adhere to military dimensional standards.

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. All of these grommets can be used outdoors.
Grommets that meet MIL-G-3036 resist hot petroleum-based oil and coolant.
Grommets that meet MS35489, AN930, and AN931 adhere to military dimensional standards.
Silicone grommets withstand a wider range of temperatures, but are not as chemical resistant as fluoroelastomer. They have a medium hardness rating, which offers a balance of cushioning and impact resistance.

Snap-In Pipe and Tubing Grommets
These grommets have two flanges that snap around holes and flex to compensate for misalignment and movement of pipe and tubing. They're often used for routing applications in panel walls. Made of plastic, these grommets are chemical resistant and won't dry out and become brittle when exposed to UV rays. All have a medium-hard rating to withstand high levels of impact. They can be used outdoors.

Brush-Style Furniture Grommets
Wire, cable, and cords pass through the grommet opening while the bristles fill in the gaps to control dust and debris. Use these grommets to eliminate cord clutter on desktops, countertops, benchtops, and other work surfaces. Push them into place.
Zinc alloy grommets are more durable than plastic grommets.
