MENSI Propane Lpg Natural Gas Pipe Water Heater DIY Burner Parts Brass Jet Nozzles 10Pcs Per Pack (M6X0.75/1.4mm（Natural）)

Two years ago I bought a NexGrill Portable (820-0033) and immediately converted it to natural gas (GASP!). NOTE: the orifices are stamped 0.80 [mm]. I bought the NG hose/regulator kit from HD and reamed each grill orifice to the appropriate size for NG. The conversion worked great.When it came time to move house (and lose my outdoor NG plumbing), I converted the grill back to LP. Since I kept the original LP hose/regulator, all I had to do was replace the orifices (yah, that's what he said). NOTE: The NexGrill Portable orifice threads are 5mm!I asked Gas Fitters/Plumbing Suppliers/BBQ stores if they sold orifices; they sent me to NexGrill. I asked NexGrill Parts if they sold orifices; they were ready to sell me two complete valve assemblies @ $24ea.After one attempt at ordering orifices that were UNEF, I figured out that I actually needed 5mm threads, not 6mm, not 32unef... FIVE, COUNT THEM, FIVE MILLIMETER THREAD PITCH! (insert angelic 'ah' here). I used a 1/32" drill bit to achieve that 0.80mm opening (I'm ok with being 0.00625mm undersize). Yes, I wrapped yellow teflon tape around those wee orifices.The snivellers are correct: these are 1/16" shorter than the originals... whoopty do! They fit. They're fine. They're not going to jump out of the bag and install themselves. If you don't have the fine motor skills to work with small parts in tight spaces, ask your 6yr old for help or hire a plumber.After I glued 'n screwed 'n taped everything back together, I sparked up the Q, grilled a celebratory porterhouse and chugged a high test.The moral of the story is: orifice size matters...

Es lo que se menciona en la reseña. Espreas para gas LP de rosca 5 mm. Le ajusto excelente a un calentador para la conversion de gas natural a LP

All the kits on Amazon do not include enough for every burner.I was worried about ordering these because they did not look like the OEM ones.Contrary to what Monument says,you can convert to Natural Gas. These worked on my Monument Mesa 5 Burner M405BZ (Lowes) should be the same for model M415BZ. Originals are M5X.75 .9mm. You could probably go a bit larger hole especially in the "Sear zone" or side burner.

Not for Weber Spirit BBQ.
