Graphite fibre is superior to any other yarn in the degree to which it combines outstanding packing properties, namely; excellent thermal conduction, smooth running, near universal chemical resistance and extreme temperature capability. The use of Type VG4 pure Graphite fibre packing provides the opportunity to extend the use of the packed gland into extreme areas of speed, temperature and chemical resistance. In more normal applications, the quality of Type VG4 will result in maintenance savings many times in excess of the actual packing cost.

Applications
For pumps and valves in extreme conditions or where the value of the best quality packing can be realised. Universal chemical resistance (sole exceptions are fuming nitric acid, oleum, aqua regia and fluorine.)
Suitable and certified for use in nuclear power plants.
Percentage of soluble chloride is less than 50 ppm.

Specification of Type VG41 pure Graphite Inconel wire re-inforced pocking can extend the use of packing in valves to the ultimate in temperature, chemical resistance and sealing integrity. Being pure Graphite, VG41 will not dry out nor harden in use.

Applications
Maximum performance valve packing providing the ultimate in braided packing for sealing integrity, capability and safety. For use in any static application where quality is paramount particularly in the nuclear and power generating industries.
Universal chemical resistance as per Style VG4.
Suitable and certified for use in nuclear power plants.

Type VC51 is Inconel Wire re-inforced for high pressure static applications to 350 Bar to give an exceptional capability, performance and lasting value packing for use up to 1 m/s.

Applications
VC5 is ideal as a rotary duty, multi-service, packing particularly for boiler feed applications.
