1.25in PCV Grommets (Pair)

The 1.25in PCV Grommets (Pair) by Edelbrock are engineered rubber seals designed for positive crankcase ventilation systems in automotive engines. These grommets serve as critical isolation bushings that mount PCV hoses and breather lines to engine block bosses, reducing vibration transfer and preventing hose fatigue. If you're rebuilding an engine, servicing emission control components, or restoring a classic vehicle, these OEM-style grommets ensure proper hose routing without fluid leakage or component damage.

Constructed from durable black rubber, the 1.25in PCV Grommets feature a 0.75-inch inner diameter (ID) that accommodates standard PCV hose sizes and a 1.25-inch outer diameter (OD) for secure mounting into engine block ports. The 0.65-inch thickness provides structural rigidity while maintaining flex to absorb engine vibration and minor movement during operation. This material composition resists petroleum vapors, oil mist, and thermal cycling typical of crankcase ventilation environments, extending component longevity compared to deteriorated original grommets.

Engine builders, restoration shops, and DIY mechanics benefit most from this pair of replacement grommets when replacing worn or cracked seals that compromise system efficiency. Installation requires simple insertion into the matching boss opening on the engine block—no special tools needed. Verify your engine's PCV port size and hose inner diameter before ordering to ensure compatibility with your specific application, whether you're servicing a small-block V8, inline engine, or vintage automotive platform.
