Corrosion Resistance Gas PTFE Spring Loaded Seal

The spring also makes up for variations in gland tolerance and normal seal wear. As a seal loading device, a metal spring is more accurate than devices such as O ring for controlling friction. There are three different spring types, each with one to three different load ratings (light, medium and heavy) to meet the exact linear friction or torque requirements.

In dynamic applications, the spring expands to offset seal wear while continuing to provide load. In conditions involving thermal cycling, the spring system continues to energize the seal lips without taking a compression set or becoming too soft or hard, the way an elastomer can.

The flexible spring allows for an extensive tolerance range that can help surmount hardware misalignment and eccentricity, without causing added friction or the inability to seal. Three different spring energized seal designs are available, offering individual attributes for each application.
