Glyd Ring Seal

The square combination seal (Glyd Ring Seal) for pistons (bore) consists of a PTFE-filled rectangular sealing ring and an O-ring. It is suitable for bidirectional pressure sealing in reciprocating hydraulic motion. The O-ring provides radial force and compensates for seal ring wear. It is generally used in conjunction with a guide ring. For cylinder diameters less than 30mm, a split (open) groove design should be used.

Features:

1. Low friction, low starting resistance, smooth movement, equal dynamic and static friction, and no creep;

2. High pressure stability under pressure and harsh conditions;

3. Long life, suitable for oil-free lubrication;

4. Suitable for sealing low-viscosity media such as water.

Applicable working conditions (limit values should not appear at the same time)
