Right fit
Installed this part on my pressure washer and started to work fine, but it started to bug down after steady use of pressure….unsure what is the cause for that now.

Just like the original
I have a Simpson 3,300 psi pressure washer I purchased from Amazon. A fantastic unit. This thermal safety valve did not trip but developed a very small leak which caused a small spray. Since this part is used to protect the pump I replaced it. Fit like a champ. Note: make sure that the slotted opening is on the bottom.

Brought my Pressure Washer back to life.
I’m in a hard water area. I stopped using my pressure washer more than 10 years ago because it would bog down and die. This replacement part did the trick. It’s easy to instal just add some Teflon tape to the threads. Feeling like a genius with my old machine running better than new.
