    Adapter used on small gas valves to check manifold pressure

    I've been seeing this more and more in the field. The latest gas valve was a White Rogers 36J22Y-202 on a Amana gas furnace. This valve had two ports, an in and an out pressure trap but they are really small Allen keys caps or I guess you could call then screws. My Manometer came with a bunch of attachments to test damn near anything except these type of gas valves.

    Any help would be appreciated.

    Have to ask your distributor for it. A new in the box gas valve comes with one too. Had my distributor get me one and a few weeks later got another with a replacement gas valve. But your right it’s very small.

    I'll ask our distributor again on Monday. When I asked the last time they looked at me like I was talking a foreign language.

    Thanks for your input.

    If it's the one I'm thinking of, try googling "adapter kit for 36g valve". Amazon has them.

    Just loosen the screw, and fit a tube over the entire port. Thats how its intended to work.

    Just loosen it a 1/4 turn and iirc 5/16 ID hose fits over it.

    I remember when I first ran into one of these valves. Had to call another tech to get the proper connection. Then I got one for myself. Ithink the valave was called a Genus valve or something like that. That adapter should be available at any parts house.

    I actually like it better than the other style.
    Can someone please explain to me -
    Why is there never enough time to do it right the first time, but plenty of time to do it twice?

    I have tried finding the correct size tubing, but have had no luck.
    As stated above, they looked at me like I was crazy when I asked at the supply houses.

    I finally drilled out a piece of tubing to go over that port.

    After reading this I thought, "omg, that makes perfect sense".

    For 20+ years I've been wondering why they haven't made an easier way to check gas pressure on gas valves. There it was staring me in the face.

    My first boss used to tell me, "step back and think outside of the box".

    Btw, this forum is awesome. I didn't have the internet back when I first got into the trade. What a valuable resource to have at your fingertips.......

    Soft rubber or silicone tubing will expand to fit. If you use hard plastic tubing you're going to have a hard time trying to fit exactly.

    What your boss said was good - but from now on try to work with the concept that There Is No Box.
