They are good quality and the threading is slightly thicker as it threads in. This was perfect because I used it to be able to pressurize a scepter water can.

You will need some thread sealant, but no washer or rubber seal. **Q: Buying in 2016 here, and pic says 2 valves whereas listing says one. Is it 2 valves or not? Reviews differ.** A: One ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works well *by A***J on April 6, 2026* For use on water pressure tank to charge with air ### ⭐⭐⭐⭐⭐ Great for DIY pressurized containers *by E***. on December 10, 2016* These valves came in a two pack.
