    What is the best way to tighten large pipe fittings?

    One of my fittings has a slow drip but it is too big for anything I have to get around and needs to be tighter than what I can do by hand. Does an oil filter wrench work or will I need a rubber strap wrench or something else?

    A strap wrench made with cloth/fabric works best for me. The rubber ones did not work for me as well. Look in the plumbing department. I think I paid around $14

    What kind of fitting? Is it a union?

    It's the threaded union on the filter housing.

    Craftsman 2 pc 16 Rubber Strap Wrench Set - - Amazon.com

    Strap wrenches work great for this...

    Hand tight should be all that's needed on unions. Did you insure the rubber 0-ring is installed on the mating surface?

    A little plumber's silicone grease might help also.
