Oil & Fuel Rear Hydraulics Quick Connector

[chuckles148]

Hey

I have been searching everywhere for looking to figure out what type of Quick connector is used.

I have seen in a few posts that it is ISO 7241-1 Series B Quick Disconnects. Is that the same as NPTF?

What is the difference between the ball style and the flat pointed one?



Thanks for your help

To the TBN forum Chuck. Glad that you joined and you came to the right place to get answers.

I can't answer that but I am sure someone on here will be able to.

Lots of quick coupler interchanges on the internet. I suspect there is no difference in ball verses needle or what ever you call it. I would compare the types between manufacturers, if they work they work. I do not think a low pressure will connect to a high pressure. At least I hope not.

Do you know if ISO 7241-1 Series B Quick Disconnects is the same as NPTF Quick Disconnects

ISO 7241-1 Series B Hydraulic Quick Disconnect Couplers

Hey Ehanson

Do you know if ISO 7241-1 Series B Quick Disconnects is the same as NPTF Quick Disconnects

The Female couplers for the rear remotes on current KIOTI Tractors are 1/2" ISO 7241-1A Couplers, which in the 1/2" size only, are compatible with ISO 5675-P Ag Couplers.. In other words, the 1/2" Pioneer 5675 Couplers are compatible in the 1/2" Size. These are common couplers, available at most farm stores. Not sure though if what you have pictured are original to the tractor, or you have an older model. All the current models use Poppet couplers, not the ball couplers as shown in your picture. Some of the older KIOTI models had 3/8" ISO 5675 Ball couplers as your picture shows.

Hope this helps.

Thanks Peter315 and MichiganIron between the size chart and your explanation I'm slowly learning,

So to recap...
1) Poppet couples NEW, Ball couples OLD but both with will work.

2) 1/2 ISO 7241-1A and ISO 5675 Ag are compatible. So what is the NPTF mean that is on alot of the couplers.

From what you both has explained I think 1/2 in. NPT Hydraulic Quick Coupler Tip is the Stucchi brand that is compatible?? or am I still not getting it

Thanks in advance

NPTF = National pipe tapered (thread) Female

It’s the threads in the end of the coupler were the hose will attach.

NPTF Refers to Nation Pipe Thread Female, which is the type of thread in the body of the coupler. The easiest way to cross reference the coupler size and style is by taking the numbers off the sleeve of the female coupler, and either post them on this forum or google them. The numbers (and letters) will identify the coupler size and type, and will help you cross reference them to other manufacturers.

NPTF does not refer to the coupler type or size. That is just a hydraulic thread designation.

The pictures in your post are not ISO 7241-1B couplers. 1B couplers have a long lead section on the male tip.

Thanks for your help

The flat pointed one provides a little more flow, maybe some other advantages. Unless you are running a hydraulic motor it likely will not mater.

These are the pictures from the current male cables I have.

From the sizing chat. That was posted. I think they are the ISO 7241-1A and you were correct it is 1/2.

The link I posted earlier can you tell if it is the 7241-1A

Have a look at this picture. Its a great profile view of the 4 most common hydro quick connects that we would use, and their designations and compatibility.


The first one in the picture, the HT series flush face, is nice, as its easier to keep the faces clean and keep debris out of your system when hooking up. These are commonly found on skid steers, and are very durable. But they can be notoriously difficult to hook up, compared to other types.

For my tractor and equipment, I'm quite partial to the series A, as the poppet is more durable and leaks less over time than the agricultural style ball. That flat end on the poppet takes most of the beating over time, which saves the sealing surface. You can also get a series A version that has a small button on the poppet that allows for the relieve of residual pressure that makes hookups much easier. see part# VP8010-4P-DC, or click on this link Pioneer 1/2 in. Connect Under Pressure Tip, 1/2 in. NPTF at Tractor Supply Co.

Thanks everyone for you help, I got all the hose and couplers I needed.

One last question.

Do I need to put hydraulic fluid in the hose, or will the tractor be able to bleed the air out.

 

[xcgreene]

System will bleed air quickly by itself when you first use it, just creep on the joystick so the line fills up more slowly. If you slam wide open, right off, that hydraulic oil will be like a freight train, slamming into everything as it goes through. Its not always a problem, but best be on the easy side.
