The retention function is assured by a special swivel nut with a wire-pin located in a groove, which is factory-assembled by the manufacturer. The embedded o-ring on the 24° taper ensures a high level of protection against leakage. Thanks to the large number of available types and designs, almost all common types and combinations of adjustable fittings can be implemented. With regards to their dimensioning and general design, STAUFF Connect Tube Fittings with 24° Taper / O-Ring (DKO) fully comply with the latest versions of the ISO 8434-1 standard. They are thus completely interchangeable with conventional adjustable standpipe tube fittings.
