Washdown Vibration-Damping Threaded-Rod-Mount Clamping Hangers
These hangers provide maximum corrosion resistance in wet environments and stand up to frequent washdowns with harsh cleaners and sanitizers. Rounded edges, polished surfaces, and acorn or hex nuts that conceal threads reduce the number of places for bacteria to grow and make them easier to clean. The cushion is FDA compliant for direct contact with food; it fits tightly around material to lessen vibration and prevents corrosion caused by metal-to-metal contact. The greater the hanger’s width, the heavier duty it is. Hangers have a threaded hole on top for mounting with threaded rod.
Silicone cushions withstand steam cleaning, as well as ozone, sunlight, and oxidation. PTFE cushions withstand most chemicals.

Sanitary Sealing Grommets
Style 1
Style 2
Style 3
Styles 1 and 2
Style 3
Create a sanitary seal on through-wall piping, tubing, and cables in food-, cosmetic-, and pharmaceutical-processing areas. Made of silicone, these grommets have a wide temperature range, resist washdown chemicals and cleaners, and are FDA compliant for direct contact with food. They’re also flexible, so hydraulic pressure surges, pipe expansion, and cord flexing won’t break their seal or damage them. No caulk or sealant is needed to install these grommets because their ridges form a strong seal that keeps out dust, debris, and moisture. The ridges also act as guidelines for trimming the center of these grommets to size; they’re sized to standard tube diameters.
To mount the flanges of these grommets, use their drilled holes. Flanges are 316 stainless steel to resist corrosion from washdowns with harsh cleaners and sanitizers.
Style 1 grommets work on tubing that isn’t installed yet.
Style 2 grommets have a split design to wrap over tubing that’s already in place. For a secure seal, crimp the included metal staples over the seal using pliers.
Style 3 grommets are flat, so they’re best for tight spaces.
