Spring Energizers Seals include Canted Coil Spring,Helical Spring, Cantilever V Spring, U Spring, Detached Leg Springs, Full Contact Springs. It is critical components in sealing systems, providing consistent force to maintain seal integrity across a range of operating conditions. Spring Energizers Seals springs are used within seals to compensate for pressure fluctuations, temperature variations, and material wear, ensuring a reliable and durable seal.
Handa Spring’s Spring Energized Seals are precision-engineered solutions designed for high-performance sealing in the most demanding environments. By combining the durability of high-performance polymers (like PTFE, PEEK) with precision-formed metal energizer springs, our seals ensure reliable performance in extreme temperatures, aggressive chemicals, high pressures, and vacuum conditions.
Whether you’re designing for cryogenic conditions, rotary motion, corrosive media, or high-pressure gas sealing, Handa Spring delivers superior sealing integrity across static and dynamic applications.
To help you choose the appropriate spring energized seal for your application, here’s a detailed comparison of the six types of seals:
| Spring Type | Spring Load | Deflection Range | Friction Level | Key Advantages | Typical Applications |
|---|---|---|---|---|---|
| Cantilever V-Spring | Medium | Medium | Moderate | Broad versatility; high sealing force | Aircraft engines, medical pumps, oil tools |
| Cantilever U-Spring | Low-Medium | Wide | Low | Moderate sealing force; good for vacuum and dynamic sealing | Hydraulic actuators, pneumatic valves |
| Helical Spring | High | Low | High | Highest load in small space; great for static and cryogenic | Space systems, vacuum chambers |
| Canted Coil Spring | Medium | Wide | Very Low | Uniform force over long deflection; fatigue resistant | Rotary shafts, medical tools, connectors |
| Full Contact Spring | Very High | Low | High | Continuous high force; best for gas and cryogenic | LNG, hydrogen systems, aerospace seals |
| Detached Leg Spring | High | Very Wide | Moderate | High deflection capacity; good for large seals | Compressors, flanges, industrial valves |
For more specific needs or further customization, consulting with a specialist or referring to detailed technical specifications from the manufacturer is recommended.
Spring Energizers come in various designs and materials, each tailored for specific applications. Here is a breakdown of the main types of Spring Energizers:
As the Canted Coil Spring(also known as Slant Coil Spring) in our portfolio, this solution offers light, medium, and heavy load options with diverse material choices (stainless steel, nickel alloys, etc.). Ideal for rotary seals, quick disconnects, and electrical connectors, it features in-house plating services to enhance corrosion resistance and conductivity—streamlining production timelines and reducing costs.
Materials: Elgiloy®, Hastelloy®, Inconel®, Stainless Steel, MP35N
Plating: Gold, Silver, Tin, Nickel, and More.
The Helical Spring(also known as helical wound springs) seal can withstand high loads with minimal deflection, making it ideal for static or tight sealing applications, such as bubble-tight face seals in pressure vessels or end caps for pumps and compressors, and even suitable for cryogenic environments down to -320°F.
Materials: Elgiloy®, Hastelloy®, Inconel®, Stainless Steel(301,316,304)
The V-Spring(V-shaped springs) stands as the industry-standard spring energizer, renowned for its unmatched versatility across high-demand applications like oil and gas sealing. Crafted from Elgiloy®, a corrosion-resistant cobalt alloy, it delivers a wide deflection range to accommodate dynamic loads and wear. Its robust design ensures reliable performance in harsh environments, including sour gas and offshore operations, making it a top choice for critical sealing systems such as blowout preventers and hydraulic valves.
Cantilever U-shaped springs offering a balance between load and deflection. The U-shaped design provides moderate force, suitable for applications where both flexibility and strength are needed.
The Full Contact Spring (FC Spring) delivers superior high-load capacity and wider deflection tolerance compared to helical springs. Its continuous outer-edge ribbing provides dual functionality: energizing the seal while combating thermal contraction in extreme temperatures (-200°C to +300°C). This integrated structural support ensures stability in axial applications like oil/gas valves or aerospace hydraulics, though it’s unsuitable for radial sealing.
Detached Leg Springs feature legs that are not connected to the coil body, allowing for independent movement. This design provides unique load characteristics and is used in specialized applications where standard spring configurations do not meet performance requirements. They are often used in custom applications and can be tailored to specific force and deflection needs.
