    Protect wire, cable, and cords from holes with sharp or rough edges. Found everywhere from enclosures to machine panels, these grommets keep cords from fraying to extend service life and prevent electrical shorts. With a flexible rubber design, they push easily into holes and reduce vibration in and around sensitive components.

    Multipurpose SBR Rubber—These durable grommets resist cracking and other signs of wear over long periods. However, they're not for use outdoors or with oil and harsh chemicals.
    Weather-Resistant EPDM—The best option for outdoor use, these grommets withstand long-term exposure to sunlight, rain, and ozone.
    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.
    High-Temperature Silicone Rubber—These keep their shape and strength at higher temperatures than any of our other rubber grommets.

    Expanding wings lock these grommets into the hole so they stay put when installed vertically and in vibrating equipment. They fit a range of panel thicknesses, so grommets from one pack will fit holes of different depths.
    Nylon—Hard and durable, these grommets won't scratch or deform easily. They also withstand exposure to most mild chemicals, greases, fuels, and solvents.

    Split Locking Grommets

    Image of Product. Front orientation. Contains Annotated, MultipleImages. Grommets. Split Locking Grommets.
    Snap these grommets around wire, cable, and cords you’ve already installed. Once pushed into place, their wings brace against the hole so the grommet stays put when installed vertically and in vibrating equipment. They fit a range of panel thicknesses, so grommets from one pack will fit a variety of surfaces.
    Nylon—Hard and durable, these grommets won't scratch or deform easily. They also withstand exposure to most mild chemicals, greases, fuels, and solvents.
