Williams Comfort Products 8H3838D10 Flex Line 10 Foot

Product Description

The WILLIAMS COMFORT PRODUCTS 8H3838D10 is a flexible gas supply line designed to connect gas-fired heating appliances to supply piping in residential and light commercial installations. 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.

This 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. The 10-foot run accommodates a range of rough-in distances without requiring field-fabricated pipe extensions, making it practical for both new construction and retrofit service calls.

Installation Notes

Installation must be performed by a licensed plumber or qualified gas fitter in accordance with local codes, IFGC requirements, and the appliance manufacturer's instructions. Shut off the gas supply at the main valve and verify zero pressure before making or breaking any connections. Apply thread sealant rated for gas service to all NPTF connections and pressure-test the completed assembly before restoring gas flow.
