PTFE Piston Seal and Rod Seal - Long lasting, Low friction

PTFE piston seal (PTFE rod seal) as Spring Energized Seal and Memory Packing are always the ideal choice for sealing static or dynamic pistons and rods.

ElringKlinger Engineered Plastics is manufacturer of PTFE seals and offers a broad range of standard PTFE piston seals and PTFE rod seals, supplemented by customer-specific special solutions.

In this area, the focus is on modified PTFE materials and compounds with specifically adapted properties.

Essential Advantages:

  • Outstanding dry-running characteristics
  • Low wear
  • Low friction
  • Variable friction conditions through choice of spring characteristics
  • Extremely low breakaway forces even after prolonged downtimes
  • No stick-slip effect even at low sliding speeds
  • High dimensional stability
  • High chemical and thermal stability
  • No volumetric change by swelling or shrinkage
  • Compact seal, suitable for O-ring assembly spaces in acc. with ARP 568 A, DIN 3771, and ISO 3601/1
  • Good cost-benefit ratio
  • Dimensions from Ø 2 to 3,000 mm available
  • Very good wiping effect with abrasive media, such as paints and lacquers
  • Sterilizable
  • Easy to rinse

Application Examples:

  • Automotive industry, e.g., in gasoline direct injection and in headlight cleaning devices
  • General mechanical engineering, e.g., in valves, solenoid valves, CNC machines, compressors, and vacuum pumps as well as tank systems
  • Aerospace industry, e.g., in landing gear systems
  • Food processing industry, e.g., in filling machines and metering systems
  • Pneumatics, e.g., in cylinders and other pneumatic components
  • Medical engineering and analytics, e.g., in chromatography and endoscopy
  • Offshore technology, e.g., as petroleum and natural gas seals
  • Chemical plant and equipment technology, e.g., in apparatus and container engineering
