The Triangle Combination Seal consists of a triangular PTFE sealing ring and a rubber O-ring; it is designed for single-acting pressure sealing in hydraulic and pneumatic reciprocating applications. The O-ring provides radial force and compensates for wear on the sealing ring. Thanks to the sealing ring's thin-lip design, it offers excellent follow-up compensation and sealing performance. For rod diameters smaller than 30 mm, a split (open-type) groove design should be used.
1. Suitable for both hydraulic and pneumatic applications;
2. Low friction, low breakaway resistance, smooth movement, equal dynamic and static friction, and no stick-slip;
3. Long service life; suitable for oil-free lubrication applications;
4. Compact design; easy to install and maintain;
Limit values should not occur simultaneously.
