Breather Grommets

The SPECTRE Breather Grommets are engineered rubber seals designed to regulate crankcase ventilation in automotive PCV (Positive Crankcase Ventilation) systems. These precision-molded components prevent pressure buildup inside the engine block while allowing controlled airflow, protecting internal engine seals and gaskets from premature wear. Mechanics, engine builders, and automotive enthusiasts rely on quality breather grommets to maintain proper engine breathing and extend engine longevity.

Constructed from durable rubber, the Breather Grommets feature a 1.250-inch outer diameter design that ensures secure seating in standard breather ports and valve cover openings. The rubber composition provides excellent chemical resistance to oil vapors, fuel fumes, and atmospheric moisture while maintaining elasticity across a wide temperature range. This kit format allows users to service multiple breather points on a single engine or maintain a complete spare set for future maintenance intervals.

Ideal for stock restorations, performance engine builds, and routine maintenance, these grommets work with most conventional V-8 and inline engines using OEM-style PCV systems. Installation is straightforward—simply press the grommet into the breather port opening until fully seated. Regular inspection and replacement of worn breather grommets helps prevent oil leaks, reduces harmful emissions, and maintains optimal engine performance over thousands of miles.
