Hi, On my 1 year old ZL-20 FEL, the hydraulic lines attach to the hydraulic valve with washers with attached rubber o-rings. Most of these are crushed and oozing out of the connector as they have been since the day I have received the tractor. I'm finally going to fix the leaks. I understand these are called bonded seals and and keywords like dowty also help in the internet search. I took guess based on measurements that I need a M14 seals for the ZL-20 Valve. I am not sure. Please help me clarify. I also have a ZL-30 will these be different? how about any bonded seals for the ZW-6 backhoe?
So in summary, my immediate need is to ensure I get the right part for the ZL-20 but I would just as well understand any other size bonded seal used for other Jinma hydraulic connections and I will order a set of everything. Thanks!

Well I should have listened. I read somewhere that I was supposed to measure the bonded seal from the ID of the rubber part. So I ordered 10 14mm parts. to be safe I ordered 12mm and 16mm parts also. the 16mm parts were still too small. Now I am re-ordering 18mm washers. Its funny I was in a napa store in Hillsboro OR last week asking about these. They had no clue what I was talking about. They were convincing me I had some very specialized piece of machinery. I didn't elaborate and let them continue to think I had a very high end machine.
