3R 747
BRAIDED PACKING FLEXIBLE
GRAPHITE, WIRE REINFORCED

ISO 9001 : 2000 Certified
3R 747 packing is manufactured from high purity flexible graphite that is expanded and formed into a weaveable yarn and then braided in a unique construction with wire reinforcement. The finished product retains all the inherent benefits of flexible graphite; while the wire reinforcement provides greater mechanical strength.

Applications //

3R 747 packing is particularly suited for use in high temperature, high pressure steam service. In addition, it can also handle most chemicals, acids and alkalis. This style is excellent for use in steam turbines, high temperature motor-actuated valves and for high pressure/high temperature valve applications in general.
