The reviewer found the assembly to be solidly built and straightforward to install, making it a good choice for DIY grill maintenance.

Key Features

• Fit Models: Designed specifically for Weber Q100 and Q120 series grills, it replaces valve assemblies found on models such as 386001, 386002, 396001, 516002 and 516501, which helps ensure a correct fit without modifications.
• High-Quality Construction: The corrosion-resistant brass construction is durable for outdoor use and should resist rust and degradation from weather exposure.
• Easy Installation: The assembly arrives ready to install and connects directly to the existing BBQ grill adjustable regulator so most users can replace it without replacing the hose.
• Adjustable Regulator: Built-in adjustment lets users fine tune gas flow after installation to address low-heat or inconsistent flame issues.
• Package Contents: Includes one 80477 valve regulator assembly with mounting bracket and an installation instruction sheet, so installers have the basic guidance needed to fit the part.

Who It's For

This replacement valve regulator is best for owners of Weber Q100 or Q120 series grills who are experiencing reduced heat, uneven flames, or suspect a failing valve assembly. It is aimed at DIY-minded users who prefer to repair rather than replace a whole grill and who want a direct-fit part that matches the listed Weber models.

Users who are unsure of their model or whose grill uses a different valve configuration should confirm the identification sticker location (back of a leg or bottom of a side shelf) before buying. Professional service or a different part may be a better choice for nonstandard or heavily modified grills.
