Specifications

natural graphite packing ring
1.good rebound elasticity
2.good self-lubrication
3.good corrosion resistance & sealing ability

Natural flexible packing ring is molded of pure graphite tape. It keeps all the characteristics of flexible graphite; for example, it is suitable for valve and pump in condition of violent changement on temperature and pressure. And it can be used in hot water, high temperature and high pressure condition, stream, heat exchanger liquid, ammonia, hydrogen, hydrocarbon, microtherm fluid and so on.

 

Characteristics:

1.Better self-lubrication

2.High  rebound elasticity

3.Make special style according to customers’ demands 

 

Types:

graphite gasket, graphite packing ring, reinforced graphite packing ring, corrugate graphite tape
