    '00 freightliner leveling valve goes bad, and I wanna get new one by Wabco, but Wabco dealer asked me about thread size and I cant unswer his quation becouse truck runs home now and will be here next week only.

    Thanx for help. Wabco offer valves with metric theads so I will buy metric fittings to change stock ones.

    I thought these new parts came with those crappy push-in fittings.

    Ouh yeah, they love it. They use "easy to connect" fitiilngs everywhere becouse they want trucks be assemblied faster and cheapper.
