    this swivel coupler is for use with hydraulic systems. the inside angle is usually 37 degrees instead of 45 that use in ac.
    You will need to tighten it real hard to stop the leak.
    who ever put it there, used it to reduce diameter for the relief valve.

    Hi Mate,

    Go to a Hydraulic Supplies mob (Pirtek?)

    Here it is known as an "AAM" fitting

    Happy tinkering!
