High Pressure PTFE Seals

Excellent for extreme temperatures, high pressures, high speeds and corrosive liquids & gases. The design utilizes a PTFE sealing lip characterized by low friction, lower level of wear and requires no metallic spring. The metal casing is stainless steel. Equivalent to Garlock P.S. and Elring styles.

Seals are also available in multi-lip designs.

Applications: The characteristics of these seals have lead to their use in a range of industries and applications including: Pumps, Agitators, Blowers, Rotating Compressors, Mixers, etc.

Lip Styles: These high pressure seals are available in O.D. sizes from 30mm (1.2″) up to 530mm (20.9″). The design can accommodate surface speeds up to 45 m/s (147.6 ft/s) and temperatures ranging from -90°C to 250°C (130°F to 482°F).
