Bal Seal™ spring-energized seals for rotary/reciprocating applications are precision-engineered from PTFE, PEEK, UHMWPE and other specially-formulated materials. They feature a Canted-coil™ spring energizer, which provides a constant working range of deflection to deliver longer, more effective service life.

The seals can be designed with a broad range of lip and groove configurations to maximize flexibility or ensure multiple contact surfaces that result in lower friction for various dynamic applications. The physical and material properties of these seals enable them to perform under a wide range of pressure and speed conditions. These seals can help ensure the safe, reliable operation of insulin pumps, MRI equipment and surgical hand tools.
