John Guest - always great quality
I always make the mistake of buying cheap piping and it always leaks, so end up buying twice. The second purchase is John Guest pipes and fittings, excellent quality but quite expensive. I'll never buy twice again and stick with JG. Recommended, yes absolutely.

These days, it isn't common to find a brand that ensure quality throughout. Every John Guest product I have used works flawlessly. I use this tubing for a restaurant's water purification system, and over several years, I have never had a leak, kink, or any other problem. The fittings work flawlessly every time, despite my numerous modifications of the system. The tubing is flexible enough, although you need to uncoil it and lay it out straight when you first open it or it might want to stay as a coil. Although 3/8" LDPE tubing and compatible press fit fittings are probably sold by other companies, I will stick with John Guest so I won't have to worry.

Used this tubing to move an under sink water filter to another location. Worked perfectly.
