Aro-tek hydraulic cylinder

I need an O ring for the top of an Aro-tek hydraulic cylinder for a 360 nose gear. Any ideas?
It looks like you are missing the shaft seal.

Note that I now use ball cylinder hones on cylinders.
The seals are available from many outlets. I have used www.theoringstore.com
The part numbers vary by source, but tend to identify seal type and size: ID, OD and thickness.
Note that main cylinders also have a sealing washer under the piston nut.
Also, note that early cylinders used a simple washer under the snap ring. Newer cylinders use a machined endcap that physically trap the snap ring so that it cannot slip out.
