Static Seals

Static Seals

The custom-engineered Bal Seal® static seal sets new standards for performance and reliability in static applications. Precision machined from PTFE and other premium polymers, our seal combines innovative geometries with a wear-reducing energizer to extend the service life of the critical equipment you design.

Static Seal Profiles

Static seal designs can vary greatly in their size, geometry, even orientation. But they all share a common characteristic: they don’t see motion in their service. Here’s a small sampling of the thousands of profiles we’ve engineered for specific static sealing requirements.

• Designed for use in applications with internal pressures to 3,000 psi (207bar), this seal features symmetrical lips in an axial orientation.
• This seal, ideal for use in cryogenic applications and pressures to 3,000 psi (207 bar), features an axial orientation and radial-shaped lips for improved sealing effectiveness.
• Ideal for pressures up to 3000 PSI (207 bar), this seal also features a symmetrical lip design in a radial orientation.

Static Seal Materials

The Bal Seal® spring-energized static seal gives you the ability to closely control frictional forces and optimize sealing effectiveness in a broad range of chemicals, temperatures, and pressures. Base jacket materials consist of polytetrafluoroethylene (PTFE), polyethylene (PE), polyetheretherketone (PEEK), and other specialty polymers. We combine these with advanced filler materials to enhance performance properties. Here’s a small sampling of the materials we’ve formulated for specific static application requirements.
