Warranty
Return & Refund
The RCS 36" stainless steel gas flex hose connects a built-in RCS grill or side burner to your natural gas or propane supply line. It has 1/2" female flare nuts with a 3/8" ID, is rated for 71,100 BTU, and comes with two 1/2" male flare x 1/2" MIP adapter fittings for the hookup.
Best for: Built-in grill and side burner installs where the gas stub-out is within 3 feet of the appliance connection.
RCS calls for a flex hose like this one to connect its built-in gas grills and side burners to the home gas supply. The stainless steel line bends to route around cabinet framing and absorbs small alignment differences between the stub-out and the appliance inlet. It uses 1/2" female flare nuts with a 3/8" inside diameter, and the two included 1/2" male flare x 1/2" MIP adapters let you thread onto standard pipe fittings. At 36" long, it suits installs where the gas supply sits close to the appliance.
Fits: RCS built-in gas grills and side burners on natural gas or propane
