    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.
