Standard Rubber Grommets
Online Sizes, Specifications, Pricing
MI’s standard line of rubber grommets includes 123 different size options made of durable high grade SBR rubber (the same base elastomer of most tires), which is engineered to resist abrasion, tearing, ozone and weather-related aging, and moderate petroleum product resistance.
- Volume Discounts in 3-tiered price columns.
- Multi-Item Discounts: 6+ item orders automatically priced in next lower tier than otherwise applicable.
- FREE Shipping & Handling on orders over $100 (see Order Info for details, limitations).
No Tooling Charges on Standard Grommet Sizes
All standard dimensioned grommets are available (with zero tooling/mold costs) in other compounds suited to particular application requirements like Neoprene, EPDM, Silicone, Buna-N, and Viton™ (Fluoroelastomer). We would be happy to assist and/or quote according to your needs.
Minimum Rubber Grommet Orders
We are working towards offering select rubber grommets in lower quantities, but in the meantime, minimum purchases begin under $100 per item, with generous price breaks for greater quantities PLUS multiple item orders. We will gladly try to work with you on breaking orders into smaller releases, and would appreciate the opportunity to special quote requirements for over 12 rubber grommet styles, quantities notably exceeding our standard price breaks, or to meet target or competitive pricing pressures.
Semi-Standard & Custom Rubber Grommets
MI has innumerable standard and semi-standard sized rubber grommets available, and can supply virtually any configuration of size, style, and material compound…without expensive tooling/mold costs in many cases.
