6 Spring Energized Seals Types

Product Description – Canted Coil Spring for High-Pressure Valve Sealing Our Canted Coil Springs are precision-engineered elastic sealing elements designed for high-pressure valves, hydrogen systems, aerospace fluid lines, chemical processing equipment, and critical sealing interfaces. With their unique slanted coil geometry, these springs deliver a highly stable, predictable load-deflection curve, ensuring consistent sealing performance even under extreme pressure, rapid pressure cycling, vibration, or thermal fluctuctuations. Manufactured with high-performance materials such as 17-7PH, MP35N, Inconel® X-750, or stainless steel, canted coil springs provide excellent corrosion resistance, low creep, and superior fatigue life, making them ideal for long-term, maintenance-free applications. The spring can be integrated into U-cup seals, metal-to-metal seals, PTFE/PEEK energized seals, or customized sealing grooves in valves, compressors, and connectors. Through precise control of coil angle, wire diameter, free height, and spring force, our canted coil springs maintain consistent sealing force without risk of extrusion or permanent deformation, even in ultra-high-pressure environments. Whether used for static sealing, dynamic reciprocating motion, or rotational sealing, canted coil springs ensure your system achieves leak-free reliability, extended service life, and enhanced safety performance.

Cantilever U springs, known for their versatile applications, require careful material selection to ensure optimal performance and durability.

Cantilever springs, integral to many mechanical systems, come in various shapes and designs, each suited to specific applications. Among these, U-shaped and V-shaped cantilever springs stand out for their distinct characteristics and performance profiles.

Cantilever U Spring is also known as: U Spring, Cantilevered U Spring, Meander U Spring, Meander Springs. Cantilever U springs, also referred to as U-shaped cantilever springs, are a type of mechanical spring that typically features a U-shaped design. The structure allows them to deflect under load, offering both support and flexibility to the system they are used in. These springs are typically characterized by their ability to absorb shocks, resist vibrations, and return to their original shape after deflection.      

Cantilever U Spring is also known as: U Spring | Cantilevered U Spring | Meander U Spring | Meander Springs.

From structural design to practical application, V Springs demonstrate a high degree of adaptability to the working environment of water jets.

Handa Cantilever V springs are a type of spring used predominantly in sealing applications. Their distinctive V-shaped cross-section and specific design allow them to function as efficient sealing components, particularly in environments requiring precise pressure and high performance.

Detached leg springs, often referred to as fishback or independent leg springs, are mechanical springs characterized by the separation or detachment of the spring legs from fixed anchor points. Unlike traditional springs, where the entire coil or structure is bound at both ends, detached leg springs feature one or more legs that remain free, allowing them to flex independently. This unique design grants these springs significant versatility in motion control, load distribution, and energy absorption.

Detached Leg Spring is also known as: Detached Leg Spring | Fish-back Spring | Fish Back Spring. Detached Leg Spring may be a specially designed spring. It is distinguished by the separation of its “legs” or support parts from the main body, allowing for more flexible installation and configuration.

Full contact springs are precision-engineered components designed to deliver uniform force distribution across their entire surface, ensuring optimal performance in high-stress environments. At Handa Spring, we combine decades of expertise with cutting-edge technology to manufacture springs that meet the rigorous demands of industries such as automotive, aerospace, medical devices, and renewable energy.

Full contact springs are specialized springs that provide even and uniform contact with a surface or component. In essence, they are designed to ensure that the entire contact area of the spring remains in full contact with the surface or substrate they are intended to interact with. This provides consistent pressure and force distribution, preventing potential failure points that could arise from uneven contact.

Full Contact Spring is also known as: Raco Spring,Continuous Contact Spring Full contact springs, also referred to as Raco springs or continuous contact springs, are crucial components in various sealing applications, particularly in environments requiring high reliability and durability. These springs are designed to maintain continuous contact throughout the full circumference of the sealing lips, ensuring an effective seal even under extreme conditions.

Full Contact Spring is also known as: Raco Spring,Continuous Contact Spring. Full Contact Springs are engineered to meet the highest standards of precision, durability, and performance. Whether you’re in the automotive, aerospace, or industrial sectors, our springs deliver unmatched reliability and efficiency.
