    Coremax valves. They're a PITA. If one is leaking I cut them out and install a standard port. There is a special "expensive" tool to work on them so you can replace the valve when needed.

    As if we don't have enough specialty tools of the trade and parts, now we need to carry these Coremax valves and a special tool to be able to work on them.

    Those leak all the time.

    I cut them out and put a normal fitting in.

    Marketed to OEMs as a cost savings, allows them to pull quicker vacuums in production without needing extra process ports.

    Last I checked the tool to change the valve without removing the charge is about $250 and then you need to stock replacement valves, too.
    Such a scam. I cut the bastards out whenever I can.

    Definitely the Coremax that Otto and knave posted about. Geez,seems like everyday you run in something that some OEM puts out, so you got to buy from them!

    Those have an o-ring that pops out of the stem sometimes. It scares the crap out of me

    According to manufacturer,you can't IMG_20170825_233825.jpg hook up Hoses to the Removal tool. The only way for a faster vac is this expensive device... X 2!

    So even more reason to just cut the buggers out whenever possible.

    That tool just openes the shraider more than a hose depressor and doesn't remove the valve from the path?

    Hardly seems worth it cause they still give only a ¼ fitting to connect too and the valve is still in there :rolleyes:

    I Agree,it only improves flow from 3.5 to 4.5 cfm. But I guess would be needed if using quick vac hoses without depressors.
