Hydraulic top link failure

[comancheflight]

I have an agristore hydraulic top link along with their top link hose kit. I was working on a job tonight and started to use the box blade. When I tried to extend the top link it started shooting fluid. I went to the rear to look and one of the hoses was loose on the link body. It was dark so I decided to take it home since I have to go back tomorrow anyway. When i got home I tightened the bolt up, fired it up and it squirter all over the place so I took it off and looking at the other hose i noticed it has a copper washer. It was completely gone on the leaking one any why is was so loose. This happen often?
Is this something I need to stock copper washers?
Where can I get these washers?

I know little about copper crush rings in conventional hydraulic systems, but harbor freight has an 80pc set for under 5$ #67526

ITs too bad they used those fittings/hoses on their cylinders. Thats only about the most uncommon hydraulic fitting. Wonder why they couldnt just use any of the much more common NPT, JIC, ORB, ORFS? Maybe its possible to convert to something a little more conventional??? Only time I have dealt with banjo stuff is fuel and some coolant setups. But never hydraulics so I dont know.

You could make one pretty quick if you can TIG weld. I have made them before out of copper wire formed over and appropriate mandrel like a piece of pipe or the original fitting. Once the ends meet you can TIG weld the ends together using smaller copper wire as filler rod and then file the ring smooth.

The banjo fitting is probably BSP British Straight Pipe. I have run into those once or twice. Sometimes it uses a copper sealing washer. Other times it uses a seal that looks like a copper washer except it has a thin rubber ring on the inside. Using the wrong one can make it leak. Don't ask me how I figured that out.

Discounthydraulichose.com has the copper sealing washers in BSP and metric sizes.
Surpluscenter.com has the composite copper-rubber seals in inch sizes.

An option to consider, as already mentioned, would be to get adapter fittings that take you from BSP to JIC and then not deal with the banjo fitting.

You may check with napa, they should have a assortment , those are used on hydraulic brake lines, or other places that handle brake parts for larger trucks.

If you contact Agristore, I bet that they will send you replacements at no cost to you.

Huh - learn something new every day. Never heard of a sealing system using copper crush washers.

NAPA, other auto stores, Ace Hardware...nobody has anything this size. Called Agristore they said they have never had a failure like this that they know of. They said they would give me one but I live 2 hours away. Just so haplens my wife is in Indy on business so I had her stop by. The price is only about .15 so even though they said they would give me one I told her to get half dozen for insurance.

Who hoo...the wife got home with my new washers. They gave all 6 to her...saved 90 cents....but still nice of them.
