Media

With the different properties of different springs, choosing the right spring for your application is essential. Here are some information on the characteristics of each type of spring that will help you choose the right spring for your spring energized seal: 

V-type HiPerSeal^® with Cantilever Spring

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.

• •  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 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

• •  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.
