Canted Coil Spring Energizer

A helical spring generates increasing force as it is compressed, while a canted coil spring provides a flatter, more stable force curve. This makes canted coil springs more suitable for dynamic sealing applications where low and consistent friction is required.

Key advantages include near-constant force behavior, reduced friction during operation, improved wear compensation, excellent dynamic sealing performance, and long service life in PTFE sealing systems.

They are widely used in semiconductor equipment, cryogenic valves, vacuum systems, hydrogen systems, aerospace actuators, rotary unions, and analytical instruments.

Yes. Canted coil spring energizers are commonly used in cryogenic sealing systems because they maintain stable preload force under extreme low-temperature conditions. Material selection must be properly matched for cryogenic performance.

Yes. They are widely used in vacuum systems due to their stable force output, low outgassing material options, and reliable sealing performance under low-pressure conditions.

Common materials include Elgiloy (high corrosion resistance, medical & semiconductor), Inconel X-750 (high temperature), Inconel 718 (high strength), Hastelloy C-276 (chemical resistance), and 17-7 PH Stainless Steel (general industrial use).

Spring load is selected based on seal cross-section, groove design, operating pressure, temperature range, motion type (static, reciprocating, rotary), and friction requirements.

Yes. Spring load can be fully customized based on application requirements. Custom load tuning is commonly used for PTFE spring energized seals in demanding operating conditions.

For prototyping, lead times range from   3–5 days. Production timelines depend on geometry complexity, material selection, and order quantity. Expedited options are available upon request.

They are commonly used in axial seals, radial seals, face seals, dynamic seals, and static seals.

Yes. Custom engineering support and prototype production are available. We can manufacture springs based on customer drawings or sealing system requirements.
