Securing Hydraulic Lines

Mike058 · Jan 5, 2022

I have to take a cylinder from my grapple in and have my dealer fix a pinhole leak. Getting it off looks pretty straight forward, but I'm wondering what I need to do to the open ends of the hydraulic lines. I don't know how long they'll keep it and I don't want water, dirt, bugs or whatever getting in while the lines are disconnected.
Thanks

I just put plastic sandwich baggies over the ends and secure them.

The best solution, especially for longer term, is to buy hydraulic fitting plugs to seal off the open fittings. Starting at CDN$2.99 you won't break the bank and you can keep them in y tool box for when you need them later.

Your local hydraulic shop can help you.

If you are in the habit of buying hydraulic cylinders and hoses often they will come with plastic plugs you can re-use. I tend to save them and keep them in a fittings drawer for such times when I need something.
