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

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.
TPE Rubber—These grommets combine the rigidity of plastic for a tight grip with the flexibility of rubber for easy installation.
Chemical-Resistant Vinyl Plastic—These grommets resist a wide range of acids, bases, solvents, and other harsh chemicals.

Sanitary Sealing Grommets
 |  |
Style 1 | Style 2 |
Seal out contaminants around wire, cable, cords, pipe, and tubing in food, cosmetics, and pharmaceutical plants. These grommets are made of nonporous silicone rubber and smooth, corrosion-resistant stainless steel to prevent bacteria and other contaminants from building up. They're also FDA compliant for direct contact with food. Locate the cutting lines on the exterior or underside of the grommet, then trim to the hole diameter you need.

Sanitary Split Sealing Grommets
 |  |
These grommets prevent contamination around wire, cable, cords, pipe, and tubing you’ve already installed. Often used in food-and-beverage and pharmaceutical plants, they're made of nonporous silicone and smooth, corrosion-resistant stainless steel to prevent bacteria from building up. To install, trim along the ridge to create the hole diameter you need. Then wrap the grommet around your line, clamp the staples to seal the grommet, and screw the flange onto the surface.
