I need to find the size of the o ring on the power steering 90 degree joint. I know it's 5/8" OD x 1/2" ID x 1/16 but that's american, anyone translate that into UK for me?

Is it R-06 1/2" x 1/16" on here?

 

That looks like the right thing.

5/8 is about 15.9mm
1/2 is about 12.7mm
1/16 is about 1.6mm

 

I take it you have a fluid leak after all?

 

No but was told the o ring is letting air in which makes sense as when it heats up after a few min it expands and blocks it, so no, fluids are all fine, but think the o ring just needs swapping out and seems to be quite a common thing.

Gonna flush it all out, refresh it, change o ring, and job should be a good one

Thanks for the sizes, still cant find any o rings of those exact sizes.

 

Give import car parts a ring , rather than guessing the size

 

The o-ring you've found on eBay is exactly the thing you need. Going by the measurements you've already found and posted up.

 

the same guy has a listing in mm
