With a 0.38 inch inner diameter and 3\/8 inch NPTF threaded fittings, this line provides a secure, leak-resistant connection between the gas shutoff valve and the appliance inlet. The 10-foot length gives installers working room in tight mechanical spaces, reducing the need for additional fittings or offsets. Licensed plumbers and HVAC technicians working on gas-fired unit heaters, wall heaters, and furnaces will find this connector a straightforward, code-compatible component for new installations and replacements.\u003c\/p\u003e\u003cp\u003eThis flex line is suited for residential and light commercial gas appliance hookups where a 3\/8 inch NPTF connection is specified. It is commonly used with Williams gas-fired wall heaters and unit heaters, as well as other appliances with compatible inlet fittings.
