The patented design guarantees our Seal-Rite fittings to be perfectly aligned every time. We utilize a gasket in conjunction with a proprietary shaped ferrule to achieve the strength and reliability of the radial crimp, ergonomics and smooth edges of the internal expansion, and the gasket seal of a reusable fitting. These features combine to offer the cleanest, strongest hose coupling available to the sanitary markets and eliminate bacteria concerns at all junction points.
