Weber 85663 BRNR Tube Set Summit 6B D BB 20 1/2 inches

Replacement Burner Tubes for Weber Summit

The Weber 85663 burner tube set is a genuine replacement part designed for Weber Summit gas grills. It restores even heat distribution across the cooking surface when original tubes have corroded or cracked. This set suits owners of compatible Summit models who need to return their grill to factory performance without modifying the firebox.

20 1/2 inch tube length

Each tube in the set measures 20 1/2 inches long, a dimension that must match the firebox depth of the grill being repaired. The part fits 21 listed Summit model numbers including 5290001, 5290009, 5390001, 5390009, 5790001, 5790009, 5890001, 5890009, 7790001, 7790009, 7790501, 7790509, 7890001, 7890009, 7890501, 7890509, 5290501, 5290509, 5390501, 5390509 and SUMMIT GOLD D LP. Grills not on this list will not accept these tubes.

Direct swap installation

The tubes drop into the existing burner brackets and connect to the original valve orifices, so no drilling or cutting is required. A common issue is seizing of the old mounting hardware, which can snap if forced; applying penetrating oil beforehand helps. Another frequent problem is misaligning the gas inlet during reassembly, which creates a leak that must be checked with soapy water before lighting.
