Gland Packing
Aramid Packing with Silicone Core
Braided from aramid fiber with PTFE emulsion and high-quality silicone oil impregnation. It retains good tensile strength with greater flexibility and lasting wear resistance, less repacking, no stretch and reduced sleeve wear, and is non-corrosive for good shaft protection. Suitable for fly ash and highly abrasive media. The added central silicone core provides durable elastic compensation, maintaining excellent sealing under heavy vibration, axial movement and bounce.
