MSE® Seals

Extended Heel Dual Lip

Defense, Energy, Industrial Operations, Life Sciences, Semiconductor

Canted Coil Spring Energized MSE® seals allow for lower seal friction at low pressure. The Canted Coil Spring has a flatter spring rate curve compared to finger and regular coil springs, allowing for more consistent spring force throughout its deflection. The Extended Heel Series is preferred for high-temperature/high-pressure applications. Rod and piston types use one Extended back-up gland width. The Canted Coil spring is intended for temperatures from -270°F to 550°F.
