    I use a Cat 1r 749 on the spin on base it popped the base gasket out while idling approx 60psi, this is with a new bypass check valve. I have never had this happen I install the filter with same "torque" as I always have using a band wrench. Is there a specific torque value for this filter? It be a real pisser if this happened while driving.

    Hand-tight served me well for over 20 years....no need for a filter wrench unless it's removing it....are you sure the seal from the old filter didn't stick to the sealing surface?

    Hand tight should be enough. Did it have a different brand filter on it with an O-ring in the middle and it's still there? Once upon a time I worked at a company shop that bought filters by the case. We received a whole case of filters with the wrong threaded ends in them, no where close. I would suspect something like that. Center of the filter bottoming or improper threads?

    Originally it had no filter there, then I replaced the short cap with CAT branded filters and made sure the seal always came off when switching it.
