XSPC have designed an excellent Low Profile compression fitting.Despite the low profile the tail length of the fitting is the still the same length as other brands so there are no issues with how well these fittings will hold the tubing securely in place.XSPC has also introduced the \'coin installation\' design. It\'s always been tricky to tighten compression fittings in to blocks as they just don\'t have a hexagonal base, so you\'ve never been able to use tools to tighten them up and with using pliers you run the risk or damaging or marking your fitting.XSPC have made a handy slot in the tail part of the compression fitting that means you can tighten the fitting in place, with something as simple as a coin.Finally the finish of these fittings is exeptional, far better than many of their rivals.Specificaiton:- Black Chrome Finish- For 1/2\" ID, 3/4\" OD Tubing (12.7mm ID, 19mm OD)- Low profile design- G1/4\" Thread
