Comments about Watts 1/4" FV-4M1 Auto Air Vent:

Though we needed a 1/8" but a simple nipple did the trick and it works perfectly.
Pex shipped quickly once I reminded them that it should have been shipped a day earlier as they had promised me at the time of the sale. Wonderful people to work with and I certainly would buy it again from them.

      A:

      That is the air vent. In normal operation the vent is left open 1 to 2
      turns, but if you need to keep air out for servicing some part of the system
      or a pressure test (of the float/vent) you can close this

      A:

      It's the vent for air to come out.

      A:

      The screw device on the top regulates the amount of air to be released from the air vent.  Just like a bleeder valve.  The instructions should have the correct setting labeled.  (For example, tighten screw and then back off 1 1/2 turn for proper setting)
