Description
Dense, resilient packing, plaited from high quality texturised glass yarns. Each fibre of the yarn is coated with a special lubricant to reduce fretting when compressed.
The graphited glass yarns are further lubricated with a heat-resistant petroleum-based compound, then finally coated with high purity flake graphite prior to braiding. Our Supeta XA Twist is also available for small radial section glands.
Typical applications
