Small couplers?

[Sumboodie]

Are small "air" couplers common/industry standard??

I have a diesel compression tester, which ends up not working for International 7.3L.

Online people talked about a short adapter that gives the proper clearance between the glow plugs hole (where the compression test goes) and the rocker.
Well, I must have a different kit, because it's not working, it uses a different coupler.

Trying to figure if I can buy a different female coupler or I guess a different guage?

What i have is like a $50 setup, have had it probably 5-6 years and never needed it till now.

Reviewers state that the MVA5605 only works with the Mityvac brand compression tester.

Go figure.

No idea why it's like pulling hens teeth to sort out a tester that actually works on probably the most common and plentiful light duty diesel engine made.

Bought a Lang tool adapter that's listed for the TU-15 kit, which is what I have.

Doesn't fit. Apparently there's several TU-15 kits. Go figure.

You could buy the correct air fitting that will work with your compression gauge and use a lathe cut in half and bore a hole in the opposite end. Then turn your mityvac adapters air fitting off and leave a spigot. Put the two pieces together and use staysilv 56 silver brazing and flux to silver brazing together.
