DAHL Cap & Chain for Hose Valves

The dahl 20023 Cap & Chain is a rough-brass replacement accessory designed for dahl hose valves. The cap closes the hose outlet when it is not being used, while the attached retaining chain keeps the cap secured to the valve and helps prevent it from being misplaced. It includes the sealing gasket shown with the assembly and is intended as a replacement or service component for compatible dahl hose-valve installations. dahl lists the 20023 specifically among its hose-valve caps and gaskets.
