What does a spring-energized seal do? The spring-energized seal is capable of providing longer service as compared with conventional (non-energized) polymer or elastomeric seals. This is …

Spring-energized PTFE seals are typically used in areas where elastomeric seals cannot meet the frictional, temperature, pressure, or chemical-resistance requirements of the application.

Spring-energized seals consist of a polymer jacket reinforced with a metal spring. The spring applies constant force to the sealing lips, ensuring contact with the gland surfaces and …

In addition to providing excellent sealing performance at low pressure, these seals withstand a wider range of temperatures and chemicals than U-cup seals. They’re also known as spring …

Oct 29, 2025 · Discover the definitive guide to spring energized seals. Learn how PTFE jackets & metal springs solve sealing challenges in extreme temperature, pressure & chemical …

Apr 18, 2025 · Discover what spring-energized seals are, their types, benefits, and applications in demanding industries. Learn how they outperform traditional seals.

Aug 1, 2024 · Spring energized seals are designed with a metal spring embedded within the polymer material, providing continuous force to maintain a tight seal even under extreme …

Spring energized seals are a highly reliable option when standard elastomer-based and polyurethane-based seals will not meet the operating limits, equipment parameters, or …

Spring energized seals are made up of two components: a polymer-based seal jacket and spring energizer. Spring energized seals are great for use in environments that are too aggressive for …

Spring energized PTFE seals perform reliably in a wide range of applications where conventional elastomeric seals fail due to chemical attack, extreme cold or heat, extrusion, friction or …
