Review on Coupling Aluminum Anodized Fitting Connector by Nathan Skipper

As with most Chinese-made goods, the manufacturing equipment is sufficient to keep costs down, but the quality control is not. I had never taken photos before but the end of the filter element was rough cut and unfinished meaning the filter would not lay flat to allow dirt to pass through. A little lapping with a file to get a flat surface and the addition of an o-ring means everything now goes through the filter. The quality of the machine makes a good impression.
