Spring Energizer Selection Guide

Choosing the right spring energizer is critical to ensuring long-term sealing performance under mechanical, thermal, and chemical stress. Handa Seal offers a diverse portfolio of spring types, each engineered for specific sealing dynamics—from low-friction dynamic motion to ultra-high-load static conditions.

Use the comparison table below to evaluate load characteristics, deflection profiles, friction behavior, and application suitability across our spring types. Whether you require high-temperature compatibility, wide sealing deflection, or compliance with oil & gas regulations like NACE MR0175, we provide precision-engineered solutions tailored to your sealing system.

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
Oil & Gas Spring High Medium–Wide Moderate–High Engineered for HPHT; corrosion and sour gas resistance (NACE compliant) Downhole tools, blowout preventers, subsea valves

For more specific needs or further customization, consulting with a specialist or referring to detailed technical specifications from the manufacturer is recommended.
