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

The 1-1/4 OD x 3/4 ID Alum V/C Rubber Grommets are essential components for engine builders and mechanics focused on custom valve cover modifications, intake manifold sealing, and vacuum line routing. These grommets function as vibration dampeners and weather seals in high-vibration environments, protecting hose lines and fittings from wear while ensuring fluid or vacuum integrity.

Constructed with a robust rubber outer sleeve and an aluminum inner core, the grommets are designed to withstand the heat and vibration stress found in engine compartments. The 1-1/4 inch outer diameter and 3/4 inch inner diameter are compatible with standard vacuum and coolant hose fittings, while the rubber material is resistant to degradation from fuel, oil, and coolant, ensuring long-term reliability.

These grommets are ideal for both professional installers and DIY enthusiasts working on projects such as LS swaps and carburetor conversions. They provide the necessary support for securing valve cover breather hoses and PCV lines, making them a reliable choice for various engine modifications.
