China Rotary Seals PTFE+Cardon Material for Hydraulic Cylinder Seals

Description
The DEF rotary cap seal is a bi-directional seal for use in pneumatic and low to medium duty rotary or oscillating applications. The rotary piston seal is a two piece design comprised of a standard size o-ring energizing a wear resistant PTFE cap. The rotary piston seal offers long wear and low friction without stick-slip. This PTFE outer diameter is designed with a special interference wiht the o-ring to eliminate spinning between the o-ring and seal. Special grooves are designed into the PTFE inner diameter to provide lubrication and create a labyrinth effect for reduced leakage. The seal is commonly used in swivel joints, hose reels and machine applications.
