    Nope, no o-ring. That looks like a British Standard Pipe Parallel (BSPP) high pressure compression fitting. Fittings and adaptors are out there, I don't know if a tee is available, would have to do some research about that myself.

    Not for certain, but looks like they may be DIN Metric compression fittings.

    Could get something like the 9606 with male compression on one end and male JIC on other end, then you can get a JIC tee fitting to connect to it. Have the hose assembly remade with a JIC end on it to connect to the tee.

    That sure looks like the fittings that were used on Poclain excavators years ago. Have seen tee`s on lines like that, but might take some looking to find one.

    If I remember correctly, these Kobelco fittings are the same as the old Poclain fittings. Some hose and fitting catalogs still refer to them as that.

    They're called GAZ fittings, they come in weird thread sizes (27,30,36,45mm) and all use a 1.5mm pitch thread. No O ring used. Check ATCOEQUIP's link above, part number 9247.
    We made tees by welding hydraulic hosetails into female tee adaptors.
    Do you need to tee into it for a high-flow supply?

    If you can I would suggest putting a JIC "t" in the middle of a flex line and leave the factory ends on the lines. I had a similar issue with my JCB , I ended up changeing out the fitting on my drive motors to JIC and reducing the cost of rebuilding the lines going to drive by 2/3 the cost in parts!

    Thankyou for the input Gents,

    Xcmark; l was just going to post asking that exact question, T into the flex line, remove a section to insure it remains the same lenght.

    Depending on the model, there are ports on the valve you can use.
    -3 Kobelcos had a by-pass cut spool each end.
