V-type HiPerSeal with Cantilever Spring

V-type

Features

  • V-shape spring with moderate spring rate (ratio of load vs. Deflection) .

  • Long beam leg design puts the spring load exact at leading edge of PTFE seal.

  • Replace Standard Inch fractional and AS 568A O-ring without any modification.

  • Standard spring is made of austenite series stainless steel.

  • Other special corrosion resistant materials such as Hastelloy®, Elgiloy® are also available.

  • Temperature range from -150°C to 260°C.

  • Vacuum to 210kg/cm2 standard and 700kg/cm2 extended heel.

  • Optional scraper lip design for abrasive medias or environment.
     

Recommended Applications

  • Reciprocating rod and piston seal.

  • Rotating shaft with speed 4 m/s max.

  • Wide tolerance and misaligned glands (static).

  • Face seal for external or internal pressure environment.

  • Dynamic applications up to 260°C.
     

H-type HiPerSeal with Helical Wound Ribbon Spring

Features

  • High spring rate for medium and heavy load application.

  • Produces evenly distributed load across each individual band.

  • Replace Standard Inch fractional and AS 568A O-ring without any modification.

  • Standard spring is made of stainless steel, but NACE compliant Elgiloy® and Hastelloy® springs are also available.

  • Temperature range from -150 to 300°C

  • Vacuum to 210 kg/cm2 standard and 700kg/cm2 extended heel.

  • Not suitable for wide gland tolerances, eccentricity or misalignment.
     

Recommended Applications

  • Face seal for external or internal pressure environment

  • Static rod and piston seal

  • Very slow dynamic seals

  • Vacuum and cryogenic sealing application
     

C-type HiPerSeal with Canted Coil Spring

Features

  • C-shape spring with very flat spring rate (load vs.deflection curve).

  • Available in several different spring loads.

  • Standard 302 series stainless steel springs.

  • Hastelloy springs also available upon request.

  • Available face seal shapes for internal or external pressure application.

  • Not the best choice for the abrasive medias due to the geometry.
     

Recommended Applications

  • Reciprocating rod and piston seal.

  • Rotaryshafts< 1.5 m/s.

  • Friction sensitive applications.

  • Diameter<1/2” and Cross sections < 3/32”.

  • Wide tolerance and misaligned glands.
