Detailed Product Description

This engine crankcase vent valve is pressure controlled and features a diaphragm valve design, which helps regulate the pressure inside the crankcase by venting gases back into the intake system. The valve is mounted on the cylinder head, with precise dimensions (65.3 mm height, 181 mm length, and 96 mm width) to fit Volkswagen CC engines accurately. The housing is made from polyamide 6.6, a robust and heat-resistant material, while the seals use a combination of fluoride rubber (FPM) and polyacrylate rubber (ACM) to provide reliable sealing under varying temperature and pressure conditions.

Common Applications and Issues Addressed
