Dont waste your money. I purchased this shutoff valve to put on a generator. As soon as i put it on and went to tighten it, the nut popped off of the body, it was just a little more than hand tight. I attempted to fix it myself and just ended up making it worse, now I cant return it. Should have just returned it when it didnt work.

While attempting to install the valve, the snap ring that holds the nut to valve popped lose. In an effort to try to repair the valve I damaged it and now cannot return it. Sure that is my fault, but now I am still without a working generator. Will be ordering from another manufacturer.

My application was for the gas tank attached to a Yamaha MZ360 engine that powers my generator. The generator didn't come with a fuel shutoff switch, and this fit perfectly for me. It allows for sufficient fuel flow to run the generator at full-tilt, it hasn't leaked after significant use, and when it's in the OFF position it truly stops all flow. Perfectly satisfied.

5 stars for fit, it is the same unit as the OEM petcock and is the same (No stars) lack of quality. This (made off shore) fuel petcock fit the (made off shore) Irwindale Industrial IG7800, 7,800 Watt (supposed) Inverter Generator ( believe this generator is marketed under different names). I had to change the original petcock because when I was removing the fuel line to drain the fuel tank, the paper thin zinc casting (or what ever flimsy metal is used) fuel line nipple snapped off in my fingers, so be very careful when removing or replacing the fuel line on the petcock as this replacement petcock is the same as the OEM petcock. This generator when set on 240V, and when under no load or a light load produced very different voltages on each hot leg, when under heavy load (240 well pump) the voltages would even out, but when wired in to the electrical panel it burned out several 120V products that happened to be on the hot leg with higher voltage. You get what you pay for, I'm not glad that I borrowed this generator (that's what I get for borrowing) but I am glade (and I learned the hard way), it is better to pay up for a guality (real) inverter generator.

Just like OEM, Glad I was able to replace mine before the hurricane hit! the only drawback is they are made of pot metal. so be careful with it. turning it on & off can break right in your hands. I was draining the gas and original did just that.
