About this product

Questions people ask us
Does this fit the current SZRPRO Sizzler Pro?
Summerset's current Sizzler Pro manual (SZRPRO32 and SZRPRO40) lists the propane main valve orifice as part 12085. Send us your model and serial number and we will confirm this orifice is the match before you order.
How many do I need?
One per main valve. Sizzler Pro manuals show 4 main burners on the 32" and 5 on the 40". Order only the number you are replacing.
Is this the orifice for the rear rotisserie burner?
No. The infrared back burner uses its own orifice. This one is for the main burners only.
