HY4300 Aramid Rubberized Gland Packing
Product Features: Woven with high-strength aramid fiber as the outer skeleton, filled with high-elasticity specialty rubber or synthetic elastomer, and impregnated with PTFE and lubricants. Combines the wear resistance and tensile strength of aramid with the high resilience and sealing compensation of the rubber core. Low coefficient of friction minimizes shaft wear, ensuring uniform preload after installation.
Technical Specifications:
Pressure: 0～20 MPa
Temperature: -50～260 ℃
Linear speed: 12 m/s
