Questions people ask us
Which grills does this orifice fit?
It is listed for Summerset Sizzler Pro natural gas grills, the pre-2025 SIZPRO32 and SIZPRO40. The 2019 Sizzler Pro manual shows 4 main valves on the 32 inch and 5 on the 40 inch.
Will it fit a standard Sizzler?
Standard Sizzler grills have their own orifice listing, MVO-SIZ-NG. Check which series your grill is before you order.
Can I use it to convert my grill to propane?
No. This is the natural gas size. Propane grills use MVO-SIZPRO-LP. Summerset notes that changing fuel needs a conversion kit and may need more than orifices, so have a gas professional handle any conversion.
What about a 2025 or newer Sizzler Pro (SZRPRO)?
The current Sizzler Pro manual for the SZRPRO32 and SZRPRO40 lists its own numbered main valve orifices. Send us your model and serial and we will check which one your grill takes. Ask us here.
Not sure this is the right orifice?
Send us the model and serial number from the rating plate on your grill, plus a photo of the old part if you have it out, and we will check it before you order. Ask us here.
