Installation Notes and Tips

Verify the thread size, connector style, and OE reference before installation. This valve uses an M16x1.0 thread, a screw-on mount, and a straight-up nipple orientation, so matching the original layout is important for proper sealing and hose routing. Inspect the mating hose and surrounding ventilation components for wear or contamination during service.
