Black Neoprene CR Rubber Grommet Round Rubber Seals for Connector Wire Harness
Type: RUBBER GROMMET/GRUMMET
Rubber grommets/grummets are essentially rubber molded parts which are placed around drilled or punched
holes to an opening in a surface. Rubber robbin mechanically eliminate sharp edges providing a cushion of
protection for the items which passes through the surface material from tearing or breaking wire, cable, tubing,
piping, hoses, air lines, rope, etc, add aesthetic value to your applications. In addition, many grommets also
serve as seals.
We offer a variety of standard elastic grommets, and we can custom make grommets and other rubber components
to your unique specifications. Silicone rubber grommets can be made in various rubber compounds including,
silicone, Buna-N, Viton Neoprene and EPDM. Our silicone grommets are available varying from sizes and shapes
that are matched to all kinds of products, such as lighting products. Each lighting rubber grommet provides shock
protection and security to keep your vehicles lights safe and also improves the overall appearance.

Neoprene Rubber, also known as neoprene polychloroprene, is an extremely versatile synthetic
rubber with more than 75 years of proven performance.
In the automotive world, neoprene is used for many under-the-hood and underbody parts that
require a reasonably priced, mid-performance polymer with a good all-around balance of
performance properties.
We can supply material as NBR, FKM, SIL, EPDM, CR, NR, PU, HNBR, FFKM, ACM ,SBR , FLS , etc...
Different elastomers have different compatibility with various chemical elements and their characteristics.See
