Review: Great connectors to modify my reverse osmosis kit to filter water to my fridge - Exactly what I needed to connect my RO water unit to my ice maker very easy to use and do not leak. Reverse Osmosis Review... I recently modified my reverse osmosis system to filter water to my refrigerator, and I couldn’t be happier with how it turned out. I was concerned about fitting everything in a cabinet, but with some careful planning, this system worked perfectly. The compact nature of the components made it easier to install, even in the tight space in an overhead cabinet. I had to do some creative adjustments, and buy a few extra parts to convert water lines, but the system was flexible enough to accommodate the setup. One of the main goals was to have filtered water directly to my refrigerator since that is where we primarily get our drinking water. The installation process was a bit of a DIY project, but it went smoothly, and the system now feeds clean, purified water straight to my fridge. It’s made a huge difference in the taste and quality of the water from the refrigerator dispenser and ice maker (cleaner looking ice too). The reverse osmosis filtration itself is top-notch, this is the second house I have installed one at. The water quality is crystal clear and noticeably better than before. It removes all the impurities, and I can really taste the difference. Even though it’s a tight space, the system is well-designed and didn’t require major adjustments beyond the initial setup. The fact that I was able to fit it in a small cabinet and still get excellent performance speaks to the system’s versatility. After getting some hose couplers, I was pleased to find that the system runs smoothly without needing constant attention. I love that it provides filtered water without requiring much maintenance or adjustment once everything was in place.

### ⭐⭐⭐⭐⭐ Great connectors to modify my reverse osmosis kit to filter water to my fridge

### ⭐⭐⭐⭐⭐ Easy to connect & disconnect. No leaks.
*by Y***Y on January 1, 2026*

I needed these to connect 2 different water tube sizes while installing the water filter. Worked great!

### ⭐⭐⭐⭐⭐ Good adapter for garden sprayer tubes
*by B***C on July 2, 2025*

These are pretty cool little connectors at a good price. I have a 1 gallon garden pump sprayer whose 1/4" siphon tube strainer was irretrievably clogged. I did not want to buy a new $28 sprayer to replace the identical $14 sprayer I bought 5 years ago. So I bought a pack of 2 strainers here that came with about 10' of vinyl tube for about $10. Problem was that the new strainers and tube were 3/8" dia. I cut the sprayer's 1/4" tube off about 6" below its connection and used these adapters to connect the new strainers. Works better than before. I did not save a lot of money, but I have extra parts to fix my daughter's identical sprayer if it is still under that bush in her overgrown yard where she left it 3 years ago.
