I bought this hose to replace a broken hose on a compact air compressor. I measured the original hose fitting M8x1.0. The listing of this product includes a dimensional drawing with M8x1.0 connection size; However, the product specification below states that the fitting is M8x0.8. I received the item yesterday (estimated delivery date was 2 months late in August so it arrived a bit early) and unfortunately the specification on the picture was wrong. . I am returning the item. Putting aside the unsuitability of the product for my application, the hose seems very well constructed, with good quality rubber and strong connections with metal fittings. I gave it 3 stars instead of 1 because of the design.
