Description
Description
The UNF-BW UNO Half Socket x Butt Weld Hydraulic Adaptor is designed for fabricating or repairing hydraulic components where a UNO (UNF O-Ring Boss) threaded port is required.
Featuring a precision-machined UNO female half socket on one end and a butt weld connection on the other, this adaptor is ideal for welding directly into hydraulic cylinders, manifolds, tanks, valve blocks or custom hydraulic fabrications.
Commonly used by hydraulic repair workshops and cylinder repair specialists, the UNF-BW allows damaged ports to be replaced or new O-ring boss ports to be added during fabrication. Once welded into place, the adaptor provides a strong, reliable sealing surface for standard UNO hydraulic fittings.
Manufactured from high-quality carbon steel, the UNF-BW is suitable for a wide range of hydraulic repair, maintenance and OEM manufacturing applications.
