    Sanitary Split Sealing Grommets

    Image of Product. Front orientation. Grommets. 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.
