John Guest 3/8 Inch x 25 Feet LLDPE Tubing, Flexible Water Tubing for Plumbing, Blue, PE-12-EI-025F-B

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 it for a hydroponic watering system. Modular and easy to configure for my needs. As I expand, I will be back to buy more.

You might wonder who could possibly screw up tubing, but once you have tubing pop out of a fitting and water runs all over the place, you'll understand. Guest tubing handles quite a bit of pressure, and the Guest fittings *really* grip the tubing to keep it in place. I'm quite happy with the brand, and won't buy any other brand fittings and tubing again. Not worth it unless someone can prove me wrong. No, I did not get paid for this review, nor did I get free product for the review. I'm just tired of imported garbage from who knows where that does not work but is *cheep*.

I sprung a leak on my sodium hypo-chlorinator. While waiting for it to arrive, another line started leaking. It couldn’t get to me fast enough. I was excited when it arrived. Replaced all of the lines.

Needed this tubing for running my RO system to the refrigerator. Worded out great and the length was just what I needed.

Very heavy duty and very tight in the quick insert connectors.

Great product for drinking water.

I used the 3/8 tubing to run water from my under-sink filter to the icemaker worked like a charm.
