When I bought this article, product image 2 showed the fitting dimensions "M8x1.0". Now that I have received the item, the picture seems to have been corrected to "M8x0.75", which of course is not compatible with the M8x1.0 air pump outlet. If you are buying it to replace your air compressor hose, take the original hose fitting to the nearest hardware store or hardware store with a screw measuring guide to see if it is M8x0.75 (I have not confirmed that the fitting on this item is actually M8x0 is .75 as stated). Aside from the assembly, the hose seems to be put together pretty well. This is a rubber hose wrapped with a nylon braid. Both ends of the hose are crimped just like my original hose. The heat generated by the air compressor loosened my original hose at the fitting until it burst; I'm not sure if the quality of the rubber in this product reduces thermal crashes.
