Spring-Energized Metal C-Ring Seal - Sonkit Sealing Solutions

Product Description

Spring Energized Metal C-ring is an enhanced version of the standard Metal C-Ring, designed to be applied in extreme working conditions. This seal features a metallic "C" substrate with an internal helical spring that provides a consistent mechanical seating load, making it ideal for applications requiring the lowest possible leakage rates.

Enhanced Performance: The internal spring allows the seal to withstand significantly larger loads and function effectively on rougher mating surfaces compared to standard C-rings. By default, these seals are system pressure energized, requiring high bolting load but offering excellent spring back.

Due to its special structure, the Spring Energized Metal C-Ring is often utilized as a hermetic seal in high-pressure (up to 1500 bar) and vacuum environments where superior sealing performance is critical. It operates reliably across extreme temperature ranges from cryogenic lows to 800°C.
