    Do these look like 1/2" hydraulic couplers?

    On the SCV of a 1980 JD 1050 with a 75 loader, they are Pioneer couplers and are dripping, I'll probably try new O Rings first but I'm unsure if these are considered 1/2" couplers?

    There are Pioneer numbers stamped on the sleeve used to connect/disconnect the coupler. Check online, the numbers may tell you.

    I'd guess 1/4" or 3/8" but impossible to tell from your pic. Disconnect them and take a picture next to a ruler please.

    hey guys,

    i was able to find some numbers, pioneer 4010-2p, looks like they're 1/4 size. It looker like the number on the female coupler was 4050-2P. so now the question, can I get the right o rings?

    Thanks!

    Thanks Kenny!

    I thought it was kind of funny that my big old 1050 used the same fittings as much smaller tractors, but I've never had any issues with the hydraulics on this tractor being slow or weak, even though the early 1050s appear to have a reputation for slow hydraulics.

    I'll track down some o rings and see what happens.

    I seem to recall 1050's having some kind of reducer couplings in the hydraulic lines.
