Press Series
The press seal ring is specially designed for high-pressure equipment such as presses, die-casting machines, and hydraulic presses. Made from high-strength carbon graphite material with excellent pressure resistance and self-lubricating properties, maintaining stable sealing under heavy load conditions. Suitable for hydraulic systems and high-pressure reciprocating motion applications.
