1-1/4 OD x 3/4 ID Steel V/C Rubber Grommets (2)

The 1-1/4 OD x 3/4 ID Steel V/C Rubber Grommets from RACING POWER CO-PACKAGED are engineered vibration-isolation components designed for PCV (Positive Crankcase Ventilation) system mounting in automotive engine bays. Supplied as a pair, these rubber grommets provide critical damping and isolation for hose connections, reducing noise transmission and protecting components from engine vibration during operation.

Each grommet features a 3/4-inch inner diameter sized to accept standard PCV hose tubing, while the 1-1/4-inch outer diameter provides secure mounting surface contact. The vulcanized rubber compound resists heat, oil exposure, and ozone degradation common in engine compartments, maintaining flexibility across seasonal temperature ranges. The dual-thickness design—0.63 inches on one side and 1.26 inches on the opposing side—distributes stress loads across the mounting interface, extending component service life and reducing fatigue failure risk typical of single-thickness alternatives.

These grommets are essential for street-driven vehicles, performance builds, and restorations requiring OEM-specification PCV system integrity. They accommodate both standard and custom hose routing configurations where vibration isolation prevents cracking at hose connection points and reduces engine bay noise. The pair format allows complete replacement of worn grommets on dual-outlet PCV systems or provision of spares for long-term maintenance.

Racing Power's grommet specification aligns with automotive industry standards for elastomer vibration mounts, offering a cost-effective alternative to OEM-branded replacements while maintaining dimensional and material performance requirements for PCV system longevity.
