Standard and Custom Rubber Grommets

Over 50 Years of Service

Since 1947

 

For more than 50 years, Hawthorne Rubber Manufacturing Corporation has been a supplier of both standard and precision custom molded rubber grommets to the exact specifications of OEM, industrial, laboratory and engineering development groups. We mold custom rubber grommets in many different materials in a wide range of durometer hardnesses.

This list of standard grommets sizes has been developed and organized into an easy to use lookup source sorted by groove width D, then A, B, C, and E. A complete chart listing of the MS35489 sizes is also available. The form on the next linked page can be used to inform us of what your grommet needs are. We also have a toll free FAX number, 800-643-2580, that can be used to send us your blue print drawings and requests for quotation.
