6720N
Adapter packing
Adapter-dedicated braided packing made of flexible graphite yarn and PTFE fiber.
This packing is used for nuclear applications, to control chlorine ion concentration.
This packing is advantageous in sliding performance, as well as mechanical strength, because of the characteristics of the flexible graphite yarn and the PTFE fiber used for reinforcement.
