  • Adapters for grease gun - where to find, sizes, etc.

    From Chris Green@21:1/5 to All on Sat Mar 8 10:27:39 2025
    I want to replace the clumsy and difficult to use screw down greaser
    on my boat with a simple, bog-standard, grease gun.

    The existing greaser is somewhat like this one (maybe I should sell
    mine!).
    https://www.asap-supplies.com/products/driveforce-steel-remote-mounted-greaser-1-litre-807203

    It has a flexible pipe on it with a connection that screws onto the
    greaser with a 19mm (or a tiny fraction under according to my
    calipers) nut. There's a reducing adapter on the side of the greaser
    reducing the size of the greaser outlet to match the connection on the
    end of the flexible pipe.

    I'd like to simply attach a standard, cartridge refillable, grease gun
    to the end of the flexible pipe.

    What is the likely thread on that nut on the end of the flexible pipe?
    (Yes, I know, how long ias a piece of string). It's quite likely to be
    a non-metric size I think but I'm not really sure. I can detach the
    pipe and measure but it would be nice to know what my measurements
    might be and what they indicate. It's rather inaccessible so a close
    look is decidedly awkward.

    Where am I likely to be able to get an adapter to go from the grease
    gun to the pipe?

    This isn't particularly high pressure application, it just pushes
    grease into the stuffing box that stops (hopefully) water coming up
    round the prop shaft into the boat.

    I've measured a few more things.

    I'm pretty certain the grease gun I'm going to use (and most grease
    guns in fact) is 1/8" NPT (or is it more likely to be the UK equivalent,
    it is made in UK).

    The connection on the pipe has, as I said, a 19mm AF nut. The thread
    onto which that connects is 15.85mm outside diameter according to my
    calipers. I can't really come up with a pipe thread that matches
    that, any ideas anyone? It is a parallel thread and it's a union type connection, not a 'pipe' thread one.
