They shipped the nozzle assembly quickly, at a reasonable price and I was up an running in short order. Partsbuilt is my new “go to” supplier. Everything was resolved perfectly. Thank you!

Best parts and Prices you will find I have ordered multiple items from Partsbuilt and all have been exactly as described. I have also asked them questions related to installations and use. They answered my questions in a timely manner with great detail if they knew the answer and told me so if the did not have experience in that area. They are my go to provider of OEM MakerGear Parts and after market accessories!
