Product Overview
The YUCHENSHLP PCV Breather Grommet is a precision‑engineered component crafted from high‑grade black rubber. Designed specifically for steel valve covers with a 1.25″ (31.75 mm) hole, it accepts a 1″ (25.4 mm) push‑in PVC Positive Crankcase Ventilation (PCV) valve or breather. Weighing only 0.634 ounces and measuring 2.68 × 2.17 × 0.71 inches, the grommet offers a compact footprint while delivering robust sealing performance. Its dimensions—OD 1 ¼” and ID 1″—match the most common PCV valve specifications, ensuring a universal fit across a wide range of automotive makes and models. The product is identified by manufacturer part number SX-28092-B and carries the YUCHENSHLP brand reputation for durability and precision.
Usage
This gromet is intended for use in both original equipment manufacturer (OEM) and aftermarket steel valve covers. It is ideal for mechanics, DIY enthusiasts, and automotive service centers that need a reliable seal for the PCV system. Install the gromet by pressing the outer diameter into the valve‑cover opening; the inner diameter will securely hold the PVC PCV valve, preventing oil leaks and ensuring proper crankcase ventilation. Suitable for daily driving, performance tuning, and emission‑control repairs, the gromet performs consistently in various climates and engine operating conditions.
