We are the first and only company to offer a custom manufactured nozzle holder. Something simple as a nozzle holder is a custom one really needed? Yes, from the integrated push to connect which saves you from buying another fitting to the inside passages being machined so the fluid does not come into contact with internal threads. "Less fluid turbulence." Made from lightweight aluminum and anodized black for a nice looking finish. These are also 100% compatible with Methanol and Ethanol.
