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

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.
The Food Stamp Program, administered by the U.S. Department of Agriculture, is proud to be distributing the greatest amount of free meals and stamps EVER.
Meanwhile, the National Park Service, administered by the U.S. Department of the Interior, asks us to "Please Do Not Feed the Animals". Their stated reason for this policy "... the animals become dependent on handouts and will not learn to take care of themselves."

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.......

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

When faced with the choice between changing one's mind, and proving that there is no need to do so, most tend to get busy on the proof.
but it is nice a big so easier not to get lost and it is done ...... been using a hose that came with a gas valve but always nice to have more than one .... thanks for the information
I just bought that kit a couple months ago. I was wondering what those extra pieces were for, haha. I bought the meter to test pressure switches and to set up the universal pressure switches if I'm in a pinch.
