Leaking couplings

[RJJR]

Like they said!
You have the wrong type of fitting on the hose end.

I appreciate the feedback. Any chance someone knows exactly what the name of the fitting is that I should ask for? I took the couplings to the dealership the first time but it didn't help.

I thought about this and cant you just get the right size coupling for the size hose you have? Take a hose off and bring it with you.Also you might want to bring both hoses with you and get them cut to fit with out any extra slack.

Well, I have a 3/8 hose and coupling on the tractor and a 1/4 inch hose and 1/2 inch threaded nipple on the grapple. The grapple didn't come with couplings becasue it is made for a skid steer and they only provide the flat faced couplings that will not work on my tractor. I'll look tomorrow but don't think the hose comes off of the grapple easily. I think it is pressed on at the grapple. Not screwed. I'll update tommorow with pics tomorow. It got dark on me tonight.
Thanks

Are the fittings npt? Did you possibly over tighten and crack the coupler housing? I have seen that happen before, typically a hairline crack that is barely noticeable.

 

[RJJR]

No, not cracked just wrong. I'm not familair with the different styles which is most of the problem. Will strip it all down and start from scratch tomororw.
Thanks

Hope this works...
The end of the connection that is leaking needs to look like this rounded end so it tightens against the curved inner part of the other fitting.

You need to change the hose end or get a different adapter. One that is NPT rated on both sides. You don't need a swivel as the end will move on the connection o-ring anyway.

Good point and often overlooked. Not saying this is the problem here but over the years over tightening has been my biggest issue with leaking hydraulics. Just sayin.

Nice job mpham!:thumbsup:

RJJR,
As the others have stated the swivel fitting should be removed, it is what we call a JIC type fitting,not NPT. What you will need is a reducer that has NPT threads on both ends. The fitting you need would be a 1/2" Female NPT X 3/8" Male NPT, just make certain that the fitting you purchase is rated for the working pressure that your hydraulic system puts out. Hope this helps.

Also do yourself a favor and do not use teflon tape . If not used properly it will only cause problems. Use the paste form of sealant on the threads and only on pipe threads. Whenever possible use JIC type fittings they are alot less troublesome.
