Canted Coil Spring Seal

Canted coil spring energized seals utilize an canted coil spring that delivers a nearly constant sealing force over a wide deflection range. This unique characteristic allows the seal to compensate for tolerance variation, wear, and thermal expansion while maintaining stable sealing performance.

With low friction and excellent responsiveness, these seals are well-suited for dynamic applications including rotary motion, reciprocating systems, and precision assemblies. They are widely used in semiconductor equipment, medical devices, and high-performance industrial systems where consistent sealing and long service life are critical.
