Description

PILOTPACK 3435 Packing is manufactured from superior performance graphited ePTFE yarn, then braided using the ‘Crossplait’ technique of manufacture.

This produces packing that has high thermal conductivity removing heat from the running surface, which ensures cooler running packing so increasing service life.

The yarn has been specially developed using graphited PTFE with high-temperature lubricant that is an integral component of the yarn. This process ensures that the lubricant cannot be washed or leached out as can occur with some coated yarns
