LESS is MORE. These compact compression fittings connect to 1/4" Nylon main supply hose and provide drip-free security with all popular short format water/meth nozzles. (Snow nozzles are tall and will not fit. Aquamist are a dissimilar thread type.)
(This part is also available in a 3/16" equivalent, as seen assembled with clear tubing.)
Or, use it to expand to another section with male threads. Here, the part is added to a 3-port Banjo Manifold Section.
Assembly is as easy as it looks. Pass the tubing through the nut and then force it over the barb. Next, tighten the nut on top of the bulged line with hard finger torque. Secure with weak thread locking fluid, if you please.
