OmniSeal® APS (Advanced Pitch Spring) Series utilizes a unique coiled wire spring design that has a light load and characteristics of a wide range of deflection while producing an almost constant spring load. This feature permits a large wear allowance in the seal jacket while maintaining an effective sealing load.
Also, the spring can be wound in extremely small coil diameters, which makes this type of seal ideal for small cross section and small diameter seal applications. The low stressed spring makes it possible to deform the seal, allowing for assembly of rod seals into most closed glands without damaging the spring. Available to fit all AS-4716, MIL-G-5514, Industrial, Metric, JIS and custom gland sizes.
