Help!

Can you identify these retracts


I need to replace the o rings in these retracts. Any idea what they are? They belong to a 94" P-47.
Alternatively, where can I source the rings?
Thanks

Hardware store is going to be the most economical. Bring the old ones and your gear. Use some sort of compatible lube/hydraulic oil.

Bearing supply places are also a good place for o-rings and seals, if you have one nearby.

Are the O rings physically damaged? tears or chunks out of them? if not just soak them in type F trans fluid..most of the time they will get soft in a day or 2

Those look pretty bad in your picture. Could be my eyes.

The one that seals the screw on cap is pretty bad. I placed the cylinder and rod ones in transmission fluid and will try tomorrow to install them and see if
they still leak. The one on the screw on cap should be the easiest to replace, as it does not need to slide...

Just look for a place that rebuilds hydraulic cylinders and hoses, they will have them. If not send them to me in an envelope i can get you a set.

Thanks for the offer. I managed to find some o rings that fit, and so far they are holding pressure all right.
