Hydraulic lift plow hoses.

[SouthIL400]

I'm going to have two new hoses made for my hydraulic lift plow. My question is a simple one. The cylinder on the plow to the tractor.
Do I need 4 swivel fittings, 2 swivel fittings, or no swivels at all and just straight male ends? Can you tell it's already a dark, cold winter?

If you are hosing from cylinder ports to quick couplers, it can be done with no swivel fittings. Without more detailed info of what and how the hose run, that may or may not be the best way to do it.

Sorry. The cylinder on the plow to the tractor.

I understood that but can't see the details to go along with getting them hooked up. Land plow (rear) or snowplow (front)? Do the hoses have to pass through or get attached anywhere along the way that would prevent screwing them into the cylinder ports (meaning the entire hose needs to turn as each end of the hose is screwed in)? Any adapters on the cylinder? Does the tractor end of each hose just have a common quick coupler half on each of them or is it a different type of connection? What type of fittings are you using on the hoses? What are the fittings at the cylinder and tractor ends the hoses have to connect to?

You need at least one end of each hose to swivel in some manner. That can be a swivel fitting or something like a quick coupling half that can be turn on to a fixed hose end (attached at the other end so the hose can't turn to install the second end).

I would use a 1/2" street L for the fittings on the cylinder. Makes them lay down nice and not sticking up in the air.

The only reason a swivel is absolutely necessary is in locations where you can't turn the fitting or hose. Swivel fittings are more expensive and aren't as strong as solid fittings. They're strong enough but won't hold up to being hit or having something heavy fall on them as well as solid fittings.

On a simple plow cylinder, you don't need any swivels unless you like wasting money.

If you're using hoses with pipe thread, for the love of all that's Holy, don't have them made! Go to TSC or anywhere else that hoses are sold and buy them pre made. It'll be a third the cost.

Thanks to everyone for the responses and information. Here is what I'm trying to do. A Case hydraulic 3-14 trailer plow, 1955 Case 400. The cylinder has 90* 1/2" NPT ends, the tractor has the original Case breakaway couplers. I already have the Case Male plugs for the tractor side. So basically I am asking if I want two swivel ends or just one swivel end on each hose. Also, if only one swivel end on the hose, which end swivels, the tractor or the cylinder? I'm a 20 year old and It's my first tractor and plow. BTW, the tractor is 45 miles from my house, so I can't just run outside and work on it. You all on here have helped me.

If you can turn the hose ends, letting the entire hose turn, into the 90 degree fittings on the plow cylinder and turn the coupler ends onto the tractor ends of the hoses, you do not need any swivels.

Buy half inch, eight foot pre made.

OK ' now I understand the question.

Nothing but female swivels on my hoses - and I prefer JIC over NPT..

I wish I would have read all the newest responses sent this morning. I went ahead and went with one swivel and one fixed end on each hose. That just leaves one more question. Which end gets the swivel side? The cylinder on the plow or the Case break-away coupler on the tractor? I appreciate you all, thanks!

That should be fine. Screw the coupler onto the fixed end of the hose and screw the swivel end onto the fixed cylinder.

What does the swivel accomplish for you?

Most setups you want a 90 degree hyd rated elbow out of the cylinder, to the hose, and a male tip on the end of it that will fit into the tractor.

There is no place or need for a swivel.

If you happen to use the hyd cylinder on several different implements, it might be nice to have that 90 degree swivel so the hoses can accommodate different implements, you might want the hoses at different angles on different things. But swivels are weaker and the first thing to leak, so less or none is certainly better.

So dedicated to the plow, no need for a swivel that I can see, you put the 90 elbow to a spot it directs the hose in the right way and good to go.

As long as you got the hoses now it’s fine, but seems like a needless expense. Might as well put the swivels on the cylinder side, but doesn’t matter much,

Been at this for a while and have never seen swivel fittings on any cylinder street ells on the cylinder and straight in to the hydraulic couplers.
Buy a hose at Fleet and pick up the proper couplers and off you go....

You guys are thinking live swivels. He is talking hoses with female pipe or JIC swivel ends. Commonly used, no more expensive than hoses with rigid male pipe ends, and a lot more convenient.

A lot of those older cylinders and tractors were just pipe threads with lower pressure so most times it was not a problem tio use a pipe elbow or 45 to make a connection and as for the swivels the JIC will come tight when you tighten them up but are still weaker than the regular straight fitting in the end of the hose and if the hose has JIC or other such threads then he needs an adapter to make the connection. All adding expense to the job. Though with the poor quality of threads today for pipe threads he probably needs to tape them so they don't leak.

Yes I know this is YT but there is no need to be stuck in the past.

Here is a modern tractor. The hydraulic cylinders on the loader have NPT ports with male NPT to male JIC fittings. ALL of the hoses have JIC female swivel ends on them. The female quick connects for the loader valve have NPT ports and those hose ends have male NPT ends just like the OP is using. The hydrauluc top link has ORB ports and the two 90° hose ends on are male ORB live swivels that allow the hoses to change angles to match the movement of the cylinder Everything else on that tractor is either BSPP, ORB, or JIC.

The hydraulic industry pretty much abandoned taper pipe which requires a thread sealant decades ago in favor of much more reliable and easier to use ports and couplings with elastomeric or metal to metal face seals.

You should not need ANY swivels.
