PTFE Glyd Ring Seal
Product Overview
KAFLON® PTFE Glyd Ring Seals are rotating shaft seals designed for demanding hydraulic and industrial applications.
These seals are made from high-quality PTFE (Teflon) compounds, featuring low friction and excellent wear resistance. They provide reliable sealing performance under high pressure, speed, and temperature, and are ideal for pumps, hydraulic motors, and rotary actuators.
The Glyd Ring design ensures:
Stable sealing under rotary motion
Low energy loss due to minimal friction
Long service life in abrasive and chemically aggressive environments
