Grommet 3/8in hole 1-1/8 in OD 7/8in Thick

The Grommet 3/8in hole 1-1/8 in OD 7/8in Thick by STAINLESS WORKS is a precision-engineered exhaust hanger grommet designed to isolate and suspend exhaust systems while minimizing vibration transmission to vehicle frames and chassis components. This male/female configuration grommet is essential for custom exhaust installations, performance builds, and OEM replacement applications where durability and noise reduction are critical. Whether restoring a classic vehicle or upgrading a modern platform, this component provides reliable support and isolation that extends the lifespan of both the exhaust system and mounting hardware.

Manufactured from high-grade silicone with a distinctive blue finish, the grommet features a 3/8-inch inner diameter hole for bolt or stud passage and a 1-1/8-inch outer diameter contact surface that distributes load across mounting brackets. The 7/8-inch thickness provides substantial compliance and vibration damping while maintaining structural integrity under typical exhaust system weight and thermal cycling. Silicone construction offers superior chemical resistance to exhaust gases, oils, and road salts compared to rubber alternatives, ensuring long-term performance without degradation or permanent set.

This grommet benefits fabricators, restoration shops, and enthusiasts building custom exhaust hangers on trucks, cars, and specialty vehicles where standard hardware may not fit. The male/female design accommodates both bolt-down and stud-mounted configurations, making it adaptable to various frame rail thicknesses and bracket styles. Installation requires only basic hand tools; simply align the grommet between the exhaust bracket and frame mounting point, insert the fastener through the 3/8-inch hole, and torque to secure. Sold as an individual unit, multiple grommets are typically required for a complete exhaust system installation.
