PTFE Glyd Seal For Hydraulic
Product Overview
PTFE Glyd Seal For Hydraulic is a high-performance double-acting piston sealing solution designed for demanding hydraulic systems. It consists of a precision-machined PTFE sealing ring energized by an elastomer O-ring, combining the low friction properties of PTFE with the elasticity of rubber materials.
