They are a lot smaller than what the pictures show but you can also see the mm sizes so that's cool but the main thing is they work, my shipping got delayed for some reason otherwise they get the job done and the price is acceptional.

This crush washer kit is quite inexpensive for a plethora of assorted sizes. I do wish some of the thickness of the rings was a bit larger though. The plastic container for the kit is really useful for keeping the parts organized (none got mixed during shipping).I was able to use these to connect a capacitor bank to a crimped terminal connection to power a DIY hobby project. These could be useful for some DIY battery connections or junctions.

Used on a 50 psi fuel fitting. The “old” fitting/ crush washer was weeping. I installed these and fuel literally sprayed out. Pretty simple, back to back test. Apparently not soft enough to seal.Not worth the trouble to return, I’ll just use them as a regular washer kit with unusual sizes.
