Easily convert your 4″ tri-clamp storage vessels to a standard D-system Sankey for simply cleaning or dispensing.
This specially designed cap allows inspection of the interior with the simple removal of the tri-clamp. Take advantage of the convenient Sankey valve and then quickly extract the entire valve assembly to easily clean the inside.
Important Note: A PRV (pressure relief valve) is needed for your coupler or tank. Serious personal injury may result if your pressure vessel does not include this.
