Crankcase Ventilation Gasket

The oil mist separator, also known as a crankcase breather, is a versatile device used in trucks, marine vessels, agricultural equipment, and power generators. It effectively separates oil mist from the crankcase ventilation system, making it suitable for medium-duty trucks, off-road machinery, and engines over 16 liters in capacity. This reliable solution captures and removes oil mist, preventing environmental contamination and reducing the need for frequent maintenance. With its innovative design, the oil mist separator ensures cleaner emissions and improved engine efficiency.


Air Compressor Gasket

Air compressor gaskets play a crucial role in maintaining a tight seal under high pressure conditions. The choice of gasket material is of utmost importance in ensuring its durability and effectiveness. Typically, hard materials are used in compressor gaskets, such as metal bonded with rubber and RCM (Reinforced Compressed Material). These materials provide the necessary strength and resilience to withstand the demanding pressure requirements of air compressors.
