Detailed Product Description

Veepacking is a set of fabric reinforced rings comprising one support ring, one sealing
ring and a pressure energizing ring. It is a single acting piston seal.The support
ring or base ring is manufactured out of nitrile elastomer with high ShoreA hardness and reinforced with impregnated cotton fabric layers for an optimalextrusion resistance.The intermediate ring - the sealing ring - is a fabric reinforced
nitrile elastomer with good resilience characteristics enabling the radialdeflection under pressure load. Consequently the optimum sealing force is applied
to the bore to be sealed.The energiser or spreader ring is made of POM or PTFE.Its function is to ensure a uniform pre-load of the seal.In some specific applications
the energiser ring is made out of Acetal resin or Phenolic resin. Please contact our local P.S.T company for further details.
