The Brownells Natural Gas HWCT Burner Orifice Cap (Mfr Part JA0100108) is the essential replacement component for hot water cleaning tank burner systems. Designed for hot water cleaning and rinse tanks to save gas and setup costs, this orifice cap works with the specially designed burner system that features one row of specially sized and positioned holes in a ¾” pipe.
This natural gas orifice cap is compatible with the gas cock system that accommodates either LP or Natural Gas orifices. The cap regulates fuel flow for optimal performance with natural gas requiring 4″-6″ w.c. gas pressure. This is the natural gas-specific variant—distinguish it from the LP gas version if converting between fuel types.
A precision-engineered gunsmithing component, the Brownells Natural Gas HWCT Burner Orifice Cap is ideal for smiths maintaining heat-treating or cleaning tank systems. Keep this replacement on hand for reliable burner performance and consistent heating for Dicro-Clean solutions and hot water rinse applications in your workshop.
