Spring Energizer 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


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.
