Is this chemical injector the correct/best one for my washer? Thanks in advance for your help -d** A: This injector may work ok but a better option would be General Pump #100774 which is for 2-3 GPM machines. Amazon item #B01JB6D0YG **Q: I have 3200 psi /2.6gpm would this work and does the tube for trasporting the liquid come included?** A: I would suggest General Pump Model #100774 (Amazon Item #B01JB6D0YG) which is for 2-3 GPM machines. The suction tube is not included. Amazon item #B00O45UHUU would work great. **Q: What size is the threading ?** A: Both sides are 3/8" NPT threads. ## Customer Reviews ### ⭐⭐⭐⭐⭐ The General *by P***R on July 26, 2025* The General Pump soap injector is incredibly durable, standing up to all sorts of tough chemicals like aluminum cleaning acids and degreasers without showing any signs of corrosion or wear.
