Bal Seal® static/face seals

Our static/face seals are available in a wide variety of materials and sizes including very small cross sections from 0.020 in. (0.5 mm) and bi-directional designs. We offer a wide range of chemical and temperature capabilities and custom geometries. Our static face seals assemble into a gland, flange, or counterbore for internal or external pressure, static or dynamic sealing. Bal Spring™ canted coil spring energizers provide long-term performance without compression set. Because the canted coil spring energizer provides a nearly constant load over a wide range of deflection, variations in gland depth tolerance have a minor effect on seal load. PTFE-based seal materials make the seal compatible with a substantial variety of liquid and gas applications.

Internal Pressure

Spring cavity on the seal ID allows the internal pressure to aid in providing a positive seal as pressure increases. A heavy spring force is typical for static applications. Lighter spring forces can customize the load for dynamic service and applications needing a lighter force.

Seal Designs: S15, S2, US15, US2

External Pressure

Spring cavity on the seal ID aids in providing a positive seal under external pressure or vacuum. A heavy spring force is typically specified for static and vacuum service. Lighter spring forces can customize the load for dynamic service and applications needing a lighter closing force
