A chevron sealing set is a multi-part sealing set, primarily designed for translator movements. They generally consist of a pressure ring, a support ring and several chevron seals. The chevron rings are made from PTFE or other high-performance plastics and are available with different profiles.

Materials

Chevron rings

PTFE chevron seals show a relatively high level of thermal expansion and do not have the elasticity of eslastomers. The PTFE chevron sealing set should therefore be kept permanently tensioned using a spring element. This prevents the occurrence of deformation due to thermal influences. The spring force depends on the type and dimensions of the chevron seal profile. Chevron seals generally require separate guides for rods, spindles …

By adjusting the material, profile and number of parts, the chevron sealing set can be perfectly matched to your application. Because of the excellent chemical resistance of these materials, the sealing sets are mainly applied in the chemical industry and the equipment industry.

Key properties 

  • High temperature resistance
  • Best insulator
  • Anti-adhesion properties
  • High-chemical resistance
  • Inertness
  • Good slide and lubrication properties
  • Stable under compressive load

Applications

  • Plunger pumps
  • Metering systems
  • Hydraulic cylinders
  • Rotary joints
  • Rotating axles
