Where to get a new valve for my compression gauge

[opposedtwin]

Any idea where I can buy a valve for the adapter/housing in my old mercury compression gauge? You can see it’s bent.

I understand it’s different than a schrader valve like on a tire.

thanks!!

Try a common tire air valve core.

A tire valve is a high tension spring, will not work in a compression tester. You need a low tension Schrader valve made for compression testers or they will not read accurately. Link – https://miltonindustries.com/products/miltonr-deluxe-compression-tester-replacement-valve-core-box

A "Boathouse Repair" is one that done without having tools or the skills to do it properly.

Yes, what Tubs said.  When I read the OP. I knew that he needed that valve with the very light spring. On a normal Shrader, the air chuck has a projection the opens the valve. The valve for the compression tester the valve is opened only by the pressure of the air, the spring only ensures that the valve snaps closed.

Perhaps check with a good auto parts store for a replacement valve.

You’ll need a tool to get the old one out. There are probably over 100 available starting with the one on top which is also a cap for the valve stem on you car. Yours is sitting pretty high so you might be able to remove it with a small pair of needle nose but you want to be careful not to do any damage to the threads.

Got the valves and they went in like a charm.
