Our High Pressure / High Temperature revolutionary Spring Energized Seal designs and polymer components have the largest array of materials and spring designs in the industry.
High Performance Polymeric Seals
High performance polymer seals operate in a wide range of static and dynamic applications covering a wide range of environmental conditions. These materials offer greater chemical compatibility over standard elastomers with a temperature range from cryogenic to +650°F. U-cup designs can handle pressures from extreme vacuum up to 30,000 psi.
High performance seals are commonly used in aerospace, oil/gas, medical, and military applications where reliability in extreme conditions is imperative. High performance seals are primarily comprised of a polymer jacket with an internal spring energizer. This outer component is chosen based on each unique application from a large stable of materials including PTFE, PEEK, and UHMW-PE, as well as other “next generation” polymers.
The Utex engineering team balances wear, temperature, chemical resistance, and cost when optimizing seal performance. Solutions to most high performance applications can be created. Between several common seal jacket materials and three spring types, Utex boasts a vast portfolio of resources at its disposal. Utex has the ability to maximize seal efficiency by assembling the best combination of sealing capability and energizing that works best for the customer’s needs.
Dynamic Advanced Offset-Coil Applications
Advanced Offset-coil seals (ACS) are ideal for dynamic applications where low friction and extended seal life are desired. ACS springs produce relatively constant force over a wide range of working deflection, which permit low friction and large wear to achieve a long seal life.
We AccomplishedCase Study
A customer required sealing of a piston that was dynamically pulled from a bore under pressure. A linear actuator would fully retract beyond the pressure energized seal and needed to stab seal again without losing pressure. A standard seal wall would blow out and bend under such circumstances. Utex engineers crafted a unique seal stack design. The seal allowed the actuator to retract but the seal wall caught on the retainer ring before expanding too far. Through special retainer rings and sealing edge geometry, the application was a success.
