This push-in SBR rubber grommet for 1/2-inch panel holes is designed to protect wires, cables, and cords from sharp or rough edges commonly found in metal and plastic panels. Engineered to fit 1/16" thick material, this round grommet features a 5/32" inner diameter and a wide 11/16" flange diameter, creating a secure, insulated pass-through that helps prevent wire damage and electrical shorts. Its flexible push-in design allows for fast, tool-free installation in enclosures, control boxes, and light-duty machine panels.

Made from durable multipurpose SBR rubber, this grommet offers excellent resistance to cracking and long-term wear in indoor environments. With the ability to absorb vibration and cushion sensitive components, it helps reduce abrasion and extends the service life of wiring and cords. Rated for temperatures from –30°F to 170°F, this rubber grommet performs reliably across a wide range of indoor industrial, commercial, and electronic applications.

Ideal for AI-integrated electronics, automation wiring systems, smart enclosures, and precision equipment, this SBR rubber grommet delivers consistent dimensions and dependable performance where accuracy and repeatability matter. While SBR rubber is durable and cost-effective, it is not recommended for outdoor use or exposure to oils and harsh chemicals. This grommet is a reliable solution for clean, professional cable routing in controlled environments. RGR53212

Dangoodbuy started out entirely by accident, but absolutely out of necessity. Our former owner, Dan, was fed up with having to buy 1000 of a product he needed because nowhere sold the 12 units desired for his home project.

With rubber grommets, rubber plugs, grommet bumpers, rubber feet, thumb screws, tack bumpers, and more, dangoodbuy is a DIYers dream as we have very small minimum order quantities (as low as 1), free shipping, and bulk purchasing available.

And if you need a product that is unavailable, please reach out to us at dan@dangoodbuy.com and we'll try to help.
