“ASL-seals” refer to Accofluor’s Spring Activated Lip Seals.

The ASL-seal is a single-acting, spring activated PTFE seal for either piston or rod. Our range of ASL-seals are capable of covering a vast variety of applications, including:

• Static seals
• Axially reciprocating movements seals
• Rotating movement

ASL-seals often replace rubber seals in applications dealing with high or low temperatures, or with non-lubricated services. ASL-seals can be delivered with springs of many different types and materials, adjusted to demands on friction, aggressive media, requirements for high wear resistance etc.

In applications that require a high standard of hygiene (in production of food or medicine, for example), our ASL-seals can be silicone-filled, in order to close off the nooks and crannies of the spring recess.

Overview:

• 610/710
  • Typically with a helical spring
  • Designed for slow dynamic or static applications  (high sealing ability at lower pressures)
• 610A/710A
  • Typically with a V-spring
  • Dynamic applications with scraper lip, wipes media from the rod
• 610D/710D
  • Typically with a V-spring
  • With a thicker dynamic lip, for increased durability
• 610R/710R
  • Always with a V-spring
  • With clamping flange to keep the seal from rotating
• 610S/710S
  • Typically with a V-spring
  • For static applications
• 611/711
  • V-spring or helical spring
  • For internal sealing
