## Questions & Answers

**Q: Is this price for one washer or a 10 pack?  they can be bought locally for 99 cents.**
A: Yeah for just one crazy huh

**Q: Do I need a hex wrench to install this into the cylinder or do you install it in the regulator? Thank you**
A: You don’t want to get it too tight or you’ll have trouble removing it for refills. I just finger tightened mine into the cylinder without issues.

**Q: What size is the black o-ring? Is it replaceable?**
A: I've always used the plain white nylon washers. I have one of these brass ones also, but as far as I know, that black O ring isn't replaceable, unless Amazon sells em. The nylon o rings are cheap, reusable & less hassle as far as I'm concerned.If you dig out the black o ring, you may run it by an Ace hdwre & try replacing. Good luck

**Q: What oring size do I get?  Mine went bad.**
A: You should order another one. Everything eventually fails and they aren't that expensive.

    Works Great! Fixed my leaks
  

*by P***E on Reviewed in the United States on March 8, 2023*

I had a leak on my kegerator between the tank and regulator and this did the trick to seal it amazingly well. Installed it onto the tank putting some keg lube onto both sides of o-ring, removed the plastic washer from the regulator and I have absolutely zero pressure drop on my high pressure gauge after hours of having the tank turned off. What a life saver, highly recommended!
