2. Application and properties

Suitable for seals of pistons and plungers, tandem seals for a variety of liquid applications are internal seals. Before installation, the sealing lip is protruded outwards, and the cylinder liner is pressed tightly after installation to provide elasticity for the wear ring, excellent sealing results can be achieved even in the absence of pressure. It can separate the liquid on both sides of the sealing ring, so it is also suitable for the sealing of the oil chamber, and the invasion of other liquids can be prevented. High wear resistance, low friction, no crawling phenomenon.
