I am operating a CCP-52XZ-225 pump and I need to change a few of the grease fittings on the hopper for the S-tube pistons and augur. I have tried a few different types of fittings but can't seem to find the right thread. Tried a regular 1/8 and a 10mm, no go!! I almost seems just a tiny bit finer than a standard 1/8.  What the heck is this fitting??

call the guys at Concord????

I have struggled with the same problem on almost the same kind of pump.. We found out it was a cone shaped fitting  I believe at the end we just said fck it and took the one that came closest and just jammed it in there... Worked fine.. Its only to get a bit of greese in there... Not high pressure stuff or anything like that..

But I guess it should go fine to order some fittings at Concord...

yeah I emailed them, waiting patiently.....

i started doing that on one of them, and it tightened up to that "really uncomfortable point" where your gut is telling you it's gonna snap, so I backed it out

tight is tight and broke is too friggen tight !!! good luck
