Good product
Worked great, bought as a replacement for a different version and held up much better, threaded on great, easy to use, holding up great in our shop.

Great job and great quality
Great quality. All fittings came with caps to prevent stuff from getting inside during shipping and they even secure it with a good portion of wrapping to prevent it from getting damaged which was a nice touch! In the past with other companies I’ve had stuff get stuck in the ports and not catch it until it was all assembled and had to break it all down again but this one seems well build and ready to role. Update if anything changes but so far so good

The General
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. I’ve used it heavily, and it still performs like new, delivering a consistent, powerful flow that makes applying soaps and chemicals in my pressure washing setup a breeze. This injector is reliable, long-lasting, and perfect for serious cleaning jobs!

Needs Thread Tape
If you've tried any of the featured amazon injectors, they are honestly about the same quality as this. I returned one of them because water was spraying from the threads when fully tightened, and this does the same. I fixed it with some thread tape, but I shouldn't have to. It does draw.

Exactly what it says it is. Buy it you won’t be disappointed!
Exactly what I ordered, and exactly what I needed. Does what it says it will. It is being used daily on a predator 4.2gpm 4400psi pressure washer inline after a secondary external unloader. Works as it should and delivers the sauce. Make sure you get the size for your machine, and you won’t be disappointed.

Good quality brass, have not used but don’t see any issues. Installed easily and should function as expected. Hopefully no leaks but fit well and great value
