    Hydraulic Quick Couplings?

    Are there hydraulic quick couplings where the male side doesn’t have a valve, or is free flow like an air coupling? It’s not going to kill me if the boy end closes when disconnected, but I’d prefer it drained. The girl side absolutely needs to shut off.

    If not, what’s the most common 1/2” quick coupling? I’ll be maxing out at 500psi,

    I've used open couplings in the past (and love dry break couplings) but I don't think the 2 styles are compatible - pretty sure the 2 dry-break halves open each other via the center spud.

    That^ may not help you, but how 'bout this? Get an extra female coupler to drain the male-ended line when disconnected.

      To be fair, you could discharge the male-end pressure by holding it tip-to-tip with another male end, but I'd almost rather use my hand.
      Really, using a female-end coupler is the most efficient and effective way to drain that male fluid pressure, and it just seems . . . natural.

      ^^^ speaking entirely in mechanical terms there, but if you take it as biological . . . fuck it, the statements stand as-is

        Have a few but they are all closed..

        Ill locate them and the post up a pic if you are in the market.

          Wow never thought a discussion about hydraulic fittings could turn me on. Thank you irate4x4

            No (soup) fittings for you..

              What you using it for? If you want a open male end you’ll prolly have to use a air style quick connect.

              The most common quick coupler would be the pioneer 1/2”. You can get them at any good farm store.

                If this is for AG equipment planter vacuum motors use a male tip with 6 holes so that if it wasn't hooked up it couldn't blow the seals out of the hydraulic motor.

                  It’ll drain on its own because the other end is open. I just like to blow compressed air through the male part when it gets disconnected.

                    It hooks up the coolant to barrels I am chambering in the lathe. I’m been using an air coupling for years trouble free but I’m about to bump the pressure up towards 500psi.

                    The ones you linked should work. I wonder if there’s no pressure behind it, if I could push that ball in on the male side with an air nozzle to blow it out?

                      or buy two females, and then make a female to air chuck adapter hose.

                        There are flat faced QC that are designed to connect with some back pressure on the lines. Flat face QC are designed to be less restrictive flow vs ball or poppet style couplers.

                          Pressure washer fittings work like that. Male always open.
