Eclipse Canted Coil Spring Seals employ a specialty wound wire spring installed in a polymer jacket. The canted coil is unique in the sealing industry because of its semi-linear load curve. As an engineered loading device, canted coil springs display a very constant load over a large deflection range. This feature allows Canted Coil Spring Seals to operate in friction sensitive applications like HPLC, encoders and flap actuators with consistent performance. Seals used in battery operated devices utilize these seals – minimizing seal friction and optimizing battery life. On the other end of the spectrum, Canted Coil Spring Seals are used with heavy load springs for use in highly viscous media such as epoxies and urethanes. Eclipse maintains an extensive inventory of canted coil spring making it possible to tailor seal requirements to nearly any application.
