I purchased this adapter so I could use it with my snap on pressure tester I didn’t realize when I bought the Lang diesel glow plug pressure port that I would need this adapter. For the money I think it’s a little over priced But I got tired of trying to figure out how to adapt it so I just bought this one. He got the job done so I guess I can’t complain too much

I have the cheap HF diesel compression gauge. I bought a Lang fitting for my GM 6.5 TD hoping it’d fit the HF meter. It doesn’t. So I bought this adapter. Then removed the Snap-On end of it and put one of the fittings included in the HF kit and I have a HF gauge to Lang glow plug adapter. Still cost less that the big HF kit.

This was to add to my snap on diesel compression tester. It does fit the quick connector correctly which I wasn't certain of until I tried it.

Female end fits the OTC tester, but the male end does not go into my TE-15 gauge, too large. Took it apart and found the gauge and fitting opposite threads. Will try to attach photos.
