Watertight Sealing Grommets

Rated IP68, these grommets form the tightest seal we offer so no water can leak through the hole. They also seal out dirt and other contaminants, even invisible particles as fine .075 mm. Use them anywhere standing or pooling water is a concern. The flange screws onto the surface for a secure hold.

Horizontal Orientation

These grommets protect 90° bends in cable running along walls, roofs, and other flat surfaces.

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.

Glass-Filled Nylon Flange—The tough, durable plastic keeps its shape and strength through repeated bumps, kicks, and scrapes.

FDA-Compliant Raised-Bulb Surface Guards

Protect surfaces, edges, and machinery in commercial kitchens, processing plants, and prep areas. These guards are made from FDA-compliant silicone for direct contact with food. Their raised bulb profile adds cushioning to absorb more impact than flat guards to reduce dents and scratches from carts and equipment.

Plain Back—Install with screws, nails, or construction adhesive.

Extra Flexible—Bend these guards around tight curves and contours. They’re often used to protect columns and irregular equipment surfaces.

A raised profile adds cushioning to soften impact and shield walls and flat surfaces from bumps and scrapes. Originally used as rub rail for boats, these guards are made from tough, weather-resistant materials that hold up indoors or outdoors. They're often used to line loading docks, protect equipment in busy areas, or create impact-resistant barriers along workstations.

Plain Back—Install with screws, nails, or construction adhesive.

EPDM—EPDM surface guards are more abrasion resistant than vinyl plastic guards.

Vinyl Plastic—These guards resist water and common cleaning solutions so they are easy to wash down and maintain.

Extra Flexible—Bend these guards around tight curves and contours. They’re often used to protect columns and irregular equipment surfaces.
