1-1/4 OD x 1 ID Steel V/C Breather Grommets 2p

The 1-1/4 OD x 1 ID Steel V/C Breather Grommets are essential components for crankcase ventilation, designed for engine builders and performance mechanics who prioritize reliability in their breather systems. Sold as a pair, these steel grommets serve as mounting insulators and sealing elements in forced ventilation setups, effectively preventing oil carryover while isolating breather lines from engine vibration.

These grommets feature a 1-1/4 inch outer diameter and a 1 inch inner diameter bore, providing a precision fit for standard braided hose and hard-line combinations commonly used in valve cover breathing systems. The steel construction offers resistance to oil saturation and thermal degradation, ensuring dimensional stability across a wide range of temperatures typical in modified engines. The design creates a vibration-dampening interface, reducing noise transmission and preventing fatigue failure at connection points.

Mechanics working on LS, big-block Chevy, and traditional carbureted platforms can benefit from these grommets when retrofitting catch-can systems or upgrading factory PCV arrangements. Their robust design is particularly useful for applications where engine performance and reliability are critical, making them a valuable addition to any performance build.
