Direct-fit replacement knob

This Weber 70868 sear knob assembly is a genuine part for Summit grill models produced in 2008 and 2009. It fits 97 listed model numbers including the Summit S-470, S-670 and Built-In S-460 and S-660 series. Owners of those specific grills can restore the original sear-station control without adapting generic hardware.

Steady control at high heat

The knob operates the sear burner valve directly, so it endures the same radiant heat the burner produces during extended pre-heat and cooking sessions. Its construction matches the factory specification for those Summit models, meaning the pointer and grip remain secure when the grill runs at searing temperatures for long periods.

Press-on installation with model verification

Installation is a simple push onto the valve stem; no tools are required. The critical step is confirming the grill model number against the 97 supported codes before ordering, because Summit valves differ across production years. Buyers who need a different valve stem diameter or a knob for a non-Summit Weber series will not be served by this part.

Questions about this item

Does the Weber 70868 sear knob assembly generate any heat or noise during extended grill sessions?

The sear knob assembly is a mechanical control component with no motor or electronics, so it produces no heat or noise during all-day grilling.

What existing grill hardware must I already own for the Weber 70868 knob to install and function?

You need a compatible Weber Summit model such as the S-470, S-670, or Built-In S-460/S-660 from 2008 or 2009, plus the original control panel and valve stem the knob mounts onto.

Will the Weber 70868 knob fit and operate correctly on older Summit models I may still be using?

The part fits 97 listed Summit model numbers covering 2008 and 2009 S-470, S-670, and Built-In S-460/S-660 variants, so it works on those older grills when the original knob is worn.
