Hydraulic line adapter question

[Midniteoyl]

As an example, you looking to make the final look like whats circled (his is 3/8" to 1/2" Male using a 3/8" to 1/2" adapter):

edit: wrong image

Thank you fellas for the help very much. I believe my female coupler is 1/2 after looking at the identification guide but I will have to measure the male end in the morning as I can't tell if its 3/8 or 1/2. I have a pair of mics and I'll also see if there are any markings on the male end. I find it strange that the previous owner wouldn't have used 1/2 since he put new lines on it for his new tractor (maybe two years old). Would it be uncommon or odd to put or not put a 1/2 end on a 1/4 line?

Thank you for the pic Midniteoyl

You mean a 1/2" coupler there, right?

Totally normal. The next implement might need the flow from a full 1/2". And you would not want to have to change the female couplers on the tractor when swapping implements.

You may need to stack adaptors to go from the common 1/2" threads on the coupler to the 1/4" threads on the hose. If indeed it has threads. The hose may have other fittings on the ends and they may not be the same 1/4" as the hose.

No, I meant on the hydro line. I mean, why replace lines and not use a 1/2 male end. Especially if you have a new/newer tractor. Or is it because the implement is so old that the previous owner had no choice but to use a 1/4 line and I didn't see that he was using a adapter?

Some tractors use a mix of sizes. There's a thread here for, I think, PowerTrac, showing a 1/4" coupler right next to a 1/2" one. I bought a manure grapple once that had 1/4" lines that was used on skidsteer. Owner put them on 'cause that's what the size thread was on the cylinder. Sometimes 1/4" is used to help control the sensitivity on machines with higher flow rates. Point is, there are a verity of reasons why it was done. If you want to change the hose, go ahead, but the easiest and cheapest solution is to just grab the adapter and be done with it. You are over thinking it

I agree on over thinking it lol. I went to 2 TSC's and a RK, they were all out of the adapters. I couldn't find my mics (still boxed up from a move) but I did take the hose with me to try at the store but that was pointless. I did thread on a 3/8's coupler on the male end and it fit but it measures closer to the .56" on the male end which is for 1/4'' and for sure not .75 for 3/8 . I'll be going up the road to a tractor shop in the morning and will take the line with me. I believe the previous owner just used the fitting size on cylinder when he made new lines instead of just adapting to a 1/2 or 3/8 line and using a adapter for his 1/2'' coupler on his remote. Same ending but a head scratcher. Anyways, thanks everyone for their time.

The coupler did read pioneer 4250 which after looking up is 1/2.

The Previous owner most likely put something like a Parker 4010 1/4" coupler on. You need an Parker 8010-4 and a 1/4" NPT female to 1/2" NPT male. Like Eaton 2081-8-4 or parker 15K0201-4-8C.

I did thread on a 3/8's coupler on the male end and it fit

So the hose end is 3/8"? That makes it much easier to find an adapter - 3/8" female to 1/2" male. This is typical and 100% ok.

he coupler did read pioneer 4250 which after looking up is 1/2.

Im confused.. Which coupler was the 1/2"? On the tractor?

Hose size relates to the flow of the implement. Implements or cylinders that don't need much flow can use smaller hoses. They're cheaper and easier to deal with. For example the hydraulic top and tilt links on my Branson have 1/4" hoses and ends and two stacked adaptors to get to the 1/2" threads on their quick connects. The hoses on my backhoe are 5/16. The main hydraulic hoses on my tractor are 3/8 and 1/2".
