In this review the focus is on the 64866 Valve & Regulator Assembly replacement designed for Weber Q1000 and Q1200 series grills (2014 and newer). The bottom line: this is a practical direct-fit replacement for owners who need a durable valve and regulator assembly that restores safe gas flow and adds the option to attach a full size propane tank adapter hose. For anyone repairing a Q1000/Q1200 with the matching original part number, this assembly provides a straightforward, mostly drop-in solution that emphasizes solid materials and compatibility.

Key Features

• Compatibility: Works specifically with Weber Q1000 and Q1200 series grills (2014 & newer) and listed Q series model numbers, so buyers can expect a correct fit when matching model IDs.
• Complete replacement: Ships with the valve, regulator assembly, stabilizer mounting bracket and an assembly sheet so users have the main parts needed for installation.
• Threaded mount: The threaded mount allows connection of a full size propane tank adapter hose, providing flexibility for those who prefer a larger tank option.
• Brass construction: The regulator body is heavy duty solid brass, which improves sealing, offers better rust resistance and extends the part's service life compared with cheaper materials.
• OEM compatibility: Designed to be compatible with the original part number and a long list of Weber Q series model numbers, simplifying replacement decisions for repairers.

Who It's For

This replacement assembly is ideal for owners of Weber Q1000 or Q1200 grills (models produced 2014 and later) who need a cost-effective, durable replacement for a worn or damaged valve/regulator. It is a good match for DIYers who are comfortable following an assembly sheet and making basic gas connection checks.

It is not suitable for owners of older Q100 or Q120 series grills, which are explicitly excluded, or for those who need accessories not included here such as the full size adapter hose. If you are unsure of your model year or part dimensions, measure the original part before purchasing.
