## Questions & Answers

**Q: What kind of metal is it?**
A: Brass with a chrome plating.

**Q: Does the female end come with a rubber washer inside?**
A: No washer. must use pipe dope or teflon tape.

**Q: Is it led free?**
A: Is it lead, free yes   Ant it works perfectly

**Q: Did you receive the correct 1/2” x 1/2” x 1/4” size?**
A: Yes. When I turn off the 1/4" line, the 1/2" line to my kitchen faucet remains unaffected unless I turn the 1/2" cold water supply valve, built into the wall, under the sink, off. You may want to add a 1/4" tee, with a 1/4" to 1/4" valve, after the filter to use as a flush line (If your refrigerator or ice maker doesn't have a water dispenser). When you change filter cartridges, little black charcoal specks come out in the water for the first 5 minutes. You don't want those in your ice cubes.

    Works as expected!
  

*by A***S on Reviewed in the United States on November 22, 2023*

I bought this to replace the cheap valve that was included in an RO filtration system. This one seems to be much better constructed, and after spending hours trying to get the old one to connect without leaking, once this arrived, I had it installed and working in less than 5 minutes. I recommend this product!

    So THROW AWAY that Saddle Valve!
  

*by W***W on Reviewed in the United States on September 14, 2020*

I like the fact that it is NOT a Saddle Valve. Pretty much all water filter/refrigerator ice maker water line kits (including the one that I ordered from Amazon) include a Saddle Valve. So why would you buy another water valve? Actually there are many compelling reasons.• In my case, I am a renter and I would have to opened up the wall under the sink to access the copper water pipe because the cold water supply valve is flush with the wall.• I was uncomfortable with the idea of piercing the cold water pipe anyway. Just seems like it is inviting a water leak/flood and the attendant water damage with possible mold/fungus requiring professional "remediation".• What I wasn't aware of, is that with a zinc coated steel clamp and brass valve body along with the copper water pipe a physical/chemical reaction called "electrolysis" causes the copper water pipe to corrode from a kind of "green cancer". Even if you didn't experience a leak at the time of installation, eventually a leak is guaranteed!• I also didn't know that Saddle Valves are a violation of the Plumbing Code in most states and that will hold up your building/remodel permit in most municipalities.

    Don’t buy
  

*by K***L on Reviewed in the United States on January 31, 2024*

Item isn’t as described . Leaks really bad and the 1/4 fitting isn’t a 1/4 . It’s way smaller . Waste of money
