Dormont 41 Ultra Flow Series high gas connectors are used to connect gas appliances to the gas supply line and are ideal for high BTU appliances, such as tankless water heaters, boilers, rooftop units and mobile gas meters. They feature stainless steel tubing for maintaining structural integrity over time and resisting corrosion caused by moisture. These gas connectors feature a heavy-duty grey PVC coating for protection against weather elements, UV radiation and chemicals. The zinc trivalent chromate plating provides an additional protective layer, ensuring that the flare nuts and adapters can withstand the environmental conditions and the corrosive nature of gas supply systems.
