Eclipse in Print

Thanks to our neighbors, Eclipse was given the opportunity to create our first ever print advertisement to be featured in the very first issue of Spirit of Flight Center Magazine. The Spirit of Flight Center is a local museum dedicated to the display of rare aviation artifacts. If you have a love for aviation and are in Colorado, it’s definitely something fun to see.

In our ad, we decided to feature a very simple image to outline exactly what we specialize in here at Eclipse. That focus was on custom designs for high tech applications, exactly to meet the needs of our customers. Hopefully you enjoy our ad, and don’t forget to stop by the museum and pick up your copy of the magazine!

Compare canted coil, cantilever, and helical springs to find the right energizer for your PTFE seal.
By Doug Montgomery June 24, 2025
Aside from ball valve seats or non-contact labyrinth seals, PTFE is rarely used without a secondary energizer. This is due to PTFE’s inelastic nature. Unlike urethanes or elastomers which possess an inherent springiness, PTFE is often considered an “unalive” material. Much like a lump of clay, it will not bounce back once deformed. Especially in dynamic applications, this is not a desirable quality. Fortunately, with the addition of a spring or elastomer energizer, all of PTFE’s excellent attributes can be fully exploited in terms of sealing. Much like the rest of the seal industry, Eclipse utilizes three metallic spring energizer types for the seals we manufacture. Canted Coil, Cantilever V-Spring, and Helical. While each spring type ultimately accomplishes the same task, energizing a PTFE or polymer seal jacket, we’ll see that each type has unique properties better suited to certain applications.  Figure 1 below shows generalized load versus deflection curves for the three spring types. As you can see, each one is quite a bit different, favoring distinct circumstances and applications. Though, we’ll also find out load curves are not only deciding factor when choosing a spring.
