crankcase vent valve diaphragm

The crankcase vent valve diaphragm is a crucial rubber component in automobile engines’ ventilation system, controlling pressure and releasing exhaust gases. Made of NBR material, it maintains the appropriate pressure inside the crankcase. It meets various certification standards, including ISO 9001, ISO/TS 16949, ASTM D2000, SAE J200, and REACH regulations. The diaphragm effectively controls crankcase pressure, reduces exhaust gas emissions, prevents external pollutants, improves combustion efficiency, and is durable and reliable. Its simple design and installation make it a key component in the crankcase breather valve.
