Description

Chevron seals Set VEK 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 Shore A hardness and reinforced with impregnated cotton fabric layers for an optimal extrusion resistance. It is designed with highly flexible and durable components, enabling extreme resiliency on varying environmental conditions with notable tolerance to soiling and severe friction.The intermediate ring - the sealing ring - is a fabric reinforced nitrile elastomer with good resilience characteristics enabling the radial deflection under pressure load. Consequently the optimum sealing force is applied to the bore to be sealed. The energizer or spreader ring is made of POM or PTFE. Its function is to ensure a uniform pre-load of the seal.
