List of "O" rings for Yong Heng

[johnf1966]

Hi all, from the UK here.

Does anyone have a list of the sizes for the "O" rings for the Yong heng and its hybrids. 

Green O rings are made of FKM and are for high temperature and working stress. The black O Rings are EPDM. just might be easier to buy them off ebay in bulk instead of waiting weeks for delivery from China. Appearently the bleed valve O rings tend to go most often.

BTW first post and time to visit Airgun Nation. Some great posts and sensible advice.



TIA

I have a yh almost 3 years now, the only orings to go bad so far have been the ones inside the female quick connects.

My bleed valve orings have not gone.

The second stage high pressure plastic piston rings started getting worn and I recently changed them.

They are tricky and a pain to change without damaging them but I was able to and I find my unit is actually working better than when new.

btw the yh comes with a full set of spare orings.

It is also not expensive to just buy the complete piston with rings already installed instead of going through the trouble of changing them.

they cost about $25.
