Review: Works as advertised and seems great quality - Works as advertised. The cutter was sharp and cut the tubing just fine. The diversity of the connectors were great. The tubing seems great quality. No leaks when connecting to RO system.
Review: Perfect Fitting Kit for Under-Sink Water Heater Installations 🚰🔧 - TLDR: 🌟🌟🌟🌟🌟 This kit provided the ideal solution for my under-sink water heater installation, with a great selection of fittings and ample tubing. I was in the midst of setting up an under-sink water heater and faced the challenge of integrating it with my existing water line to the refrigerator, which had a smaller-than-usual 1/4" tube. My initial attempts to install a tee in the line were unsuccessful, resulting in leaks despite trying different fittings twice. Then I found this kit, which turned out to be exactly what I needed. It came with a comprehensive assortment of fittings, making it much easier to find the right parts for my setup. Additionally, the kit included plenty of tubing, which was a huge relief. A crucial tip I learned from this experience is to avoid using clear 1/4" tubing as a substitute. It's likely to cause leaks and can jeopardize the whole installation. This kit, on the other hand, provided reliable materials that ensured a secure and leak-free setup. Overall, I'm extremely satisfied with this kit. It effectively resolved my installation challenges and made the process of setting up my under-sink water heater much smoother.

### ⭐⭐⭐⭐⭐ Great kit for fabricating a pumping system
*by C***F on June 19, 2025*

I've been having a never-ending problem with leaky pontoons on my pontoon boat. I decided to fabricate a pumping system. I used this 3/8" tubing and quick connect fittings to connect a 12 Volt water pump to the drain plug holes. This kit came with a special cutting tool that makes precise cuts in the tubing. I used 90-degree, shutoff, 3/8" pipe thread, union, and "Y" fittings. It was amazingly easy to assemble and it works great.
