    Leaky Manitowoc Tri-L-25 Filter Fittings

    I did a filter change on a Manitowoc Tri-L-25 filter set and for the life of me, I couldn't get one of the John Guest connectors to stop leaking.

    I know these fittings tend to get a "set" and if they're cocked to one side or another they'll leak. In the past, I've always been successful in tweaking the cartridge housing a bit to get the "set" back...and stop the leak, but this one just wouldn't quit.

    Manitowoc has the replacement John Guest stuff available, but if I have to replace these things, I'd much rather do it with something which is available locally.

    In the meantime, the customer has free use of one of my 5 gallon buckets to catch the drips.

    Anybody have any suggestions?

    If these are the fittings that I'm thinking of, pop the O-ring out and flip it over.

    Maybe not the perfect fix, but it works.

    Thanks for the tips.

    After looking at these thing some more, I may try simply replacing the O-rings.

    Check the line, make sure it wasnt scratched. Make sure its cut square and has a clean cut. I usually go to home depot or lowes when I really need one out in thefield.

    UPDATE...

    I went back Tuesday and the customer said it stopped leaking the next day, so he said to wait on the repair work until the next filter change.

    Go figure.
