PARKER INSTRUMENTATION

The ferrule, perhaps the most-critical component in compression fittings, is highly engineered and, to function properly requires considerable design, metallurgy, and production expertise. Not all products on the market meet these stringent requirements. The ferrule must precisely deform elastically and plastically during fitting assembly to properly grip and seal the tubing. Its front edge must be harder than the tubing to grip and seal through surface scratches and defects, but if the entire ferrule is too hard, it may not deform properly. Therefore, only the gripping edge of the ferrule is hardened while the rest has different, tightly controlled mechanical properties. Also, the hardening process must not compromise stainless steel's corrosion resistance. And finally, production processes must consistently turn out defect-free ferrules that hold tight tolerances and maintain metallurgical specifications.
