The Blu-lock tubing and fittings are of outstanding quality. I used it for my drip system to replace my current 5/8" black thin walled tubing. The Blu-lock tubing has 3x the wall thickness which makes it indestructible. Since the wall thickness is much thicker I had to drill and thread in special fittings for each individual drip line. This was well worth the time and money for this major upgrade to my system. This is a one and done, you will never have to dig up the Blu-lock system ever!
