Why Full Contact Springs Stand Apart
A cantilever V spring is defined by its distinctive “V” shape and single-point mounting, combining the rigidity of a cantilever design with the flexibility of a coiled spring. This unique structure offers:
-
Specialty Materials: From high-grade stainless steels to exotic alloys, we source materials tailored to your environment’s demands (corrosion resistance, temperature tolerance, etc.).
-
High-Load Capability: Built for heavy-duty performance, these springs generate robust, uniform force to withstand extreme pressures and dynamic conditions.
-
Extreme Environment Compatibility: Ideal for cryogenics, vacuum systems, and light gas applications at low pressures—where precision sealing is mission-critical.
-
Ready-to-Use Design: Available in continuous lengths, shipped pre-cut and ready to roll to your exact diameter (welding required after placement in the seal jacket).
In summary, Full Contact Springs redefine reliability in sealing applications: their unique 360° contact design eliminates weak points, while robust construction and material versatility ensure consistent performance across extreme temperatures, pressures, and media. Whether for standard setups or custom challenges, they deliver the precision and durability that critical industries demand.
Custom Solutions for Unique Requirements
Off-the-shelf options aren’t always enough. Our custom manufacturing capabilities include:
-
Specialty Materials: From high-grade stainless steels to exotic alloys, we source materials tailored to your environment’s demands (corrosion resistance, temperature tolerance, etc.).
-
Non-Standard Sizes: With over 100 nonstandard cross-sections and custom tooling options, we can engineer springs to fit unique geometries—even minor adjustments to “L” and “K” dimensions or aggressive changes to material width and radii.
-
Secondary Finishing: Add coatings or treatments to enhance durability, conductivity, or compatibility with specific media.
