Spring Energized Seal Products
Spring energizers are generally used to overcome the load constraints of a polymer seal jacket. Though polymers offer great sealing capacity, they lack consistency in load distribution. Energizers housed inside the polymer jacket are used to overcome variations in pressures, temperatures, and surrounding component tolerances, providing more consistent performance.
MW Components is a trusted supplier of spring energizer products worldwide through our Kemah, TX location. Some examples of our spring energizer products include V-springs, helical springs, full-contact springs, slant coil springs, and Q-connect slant coil springs.
After years of manufacturing excellence, we can create hundreds of cross-sections without the need for more costly tooling. We have invested in equipment and services that increase our products' quality and offer more value to our customers. Some examples include varied tooling capabilities, Swiss-made high-speed milling machinery, Load-Deflection Testing, laser welding, and 3D modeling software.

Spring Energizer Configurations

V-Spring
The V-Spring is a versatile spring energizer that can be used in multiple applications. It is considered the standard for spring energizers. It is widely used to assist in sealing applications for oil and gas due to its greater deflection range and the fact that it can be produced using Elgiloy (a non-corrosive material). This spring generally withstands temperatures ranging from -75 to 500 F and pressures above 30,000 psi, making it a great option for many sealing applications.

Helical Spring
The Helical spring can withstand high loads with low deflection and is ideal for static applications or those requiring tight seals. Common applications for the Helical Spring may include end caps for pumps or compressors or bubble-tight face seals within pressure vessels. This spring can even be used for cryogenic purposes since it withstands temperatures down to -320 F. For tight or static seals, this spring is the optimum choice.

Slant Coil Spring
The Slant Coil spring is one of our more unique spring types. It has a flat load to deflection curve which means that the force emitted stays constant over a wide deflection range. This feature makes it perfect for high-speed rotary systems or applications which require tight control of running friction or breakout. It may also be used within devices that require a quick disconnect where many engagement and disengagement cycles are necessary.

Full Contact Spring
The Full Contact spring, also called FC spring, can withstand the highest load and maintains a higher deflection range than the Helical spring. Continuous ribbing along the outer edge allows it to energize the seal while also acting as an added structural component inside the seal, which allows it to fight the thermal contraction of the seal jacket when exposed to extreme temperatures. Due to its configuration, the Full Contact spring can only be used in axial applications.

Top Industry Applications: Oil & Gas and Medical
Oil & Gas
Spring energizers are one of the most common components used to provide a leak-proof seal in oil and gas applications that involve extreme, dynamic environment. When paired with a durable polymer jacket, spring energizers provide leak-protection tight seal even in dynamic conditions, such as rotational or reciprocating motion. The spring ensures continuous contact between the seal and the mating surface, compensating for wear, pressure fluctuations, and misalignments.
When crafted from quality materials, spring energizers also offer exceptional resistance to high pressures, extreme temperatures, and corrosive chemicals. By preventing leaks and performing well in extreme environments, spring energized seals enhance the safety, efficiency, and longevity of critical oil and gas equipment.
Common oil & gas uses for spring energizers:
- Valves
- Pumps
- Compressors
- Downhole tools
Medical
Spring energizers provide precise, repeatable force and reliable connections in critical medical applications. Their loads and deflection are customizable, making them ideal for use in quick connect/disconnect uses for surgical instruments and diagnostic equipment, as well as and in electrical enclosures or used with data transmission cables where they are customized to meet impedance specifications to protect equipment from crosstalk interference. In EMI/RFI shielding applications, spring energizers provide an economical design that can reduce radiated and conducted interference to prevent premature failure in electrical devices.
In addition to the above, spring energizers are frequently used as leak-proof seals in infusion pumps, ventilators, and more. In seal applications, spring energizers are are paired with a polymer jacket, often made from biocompatible materials like PTFE or UHMWPE, to guard against leaks under changing conditions such as repeated movements or pressure fluctuations.
Common medical uses for spring energizers:
- Quick connect/disconnect applications
- Leak-proof seals
- Electrical connectors
