The WILLIAMS COMFORT PRODUCTS 8H3838D06 is a flexible gas connector designed for connecting gas-fired heating appliances to the gas supply line. With a 0.38-inch inner diameter and 3/8-inch NPTF threaded fittings, this connector provides a secure, leak-resistant joint between the appliance and the shutoff or supply fitting. At 6 feet in length, it offers enough reach to accommodate most standard residential appliance installations. Licensed gas technicians and HVAC professionals use this type of connector during new equipment installations and appliance replacements where a flexible, code-compliant supply connection is required.
This connector is suited for residential and light commercial gas appliance installations, including wall heaters, space heaters, and similar Williams Comfort Products units that require a flexible gas supply line. The 6-foot length allows flexibility in positioning the appliance relative to the gas outlet, reducing the need for additional rigid piping or offset fittings in tight utility spaces or mechanical rooms.
Designed as an OEM-style flexible gas connector for use with residential gas heating appliances requiring a 0.38-inch ID, 3/8-inch NPTF supply connection.
Installation should be performed by a licensed gas technician or qualified HVAC professional in accordance with local codes and IFGC requirements. Shut off the gas supply at the main or appliance shutoff valve and verify the line is depressurized before making or breaking any connections. Apply an approved pipe thread sealant compatible with gas service to all threaded joints. Never route a flexible gas connector through walls, ceilings, or floors, and do not use it where it may be concealed or subject to physical damage.
