What size is the O-ring on my power steering pressure hose??

[4mulas]

Anyone know the size of o-ring that goes on the hose, The part that goes into the box. This is on a 74 A body but I imagine all 73 and up boxes are probably the same. (maybe even 71 and up)
It’s a Saginaw pump if that matter.

This is the o-ring included when you buy a new pressure hose like the one pictured

Yeah, they usually come with the o-ring.

Should be 3/8". Take an open end wrench and measure where the o ring goes.

It’s the other end, more like 5/16 probably even a 1/4” as the tube where is slide over is .265”. Was just hoping some had been through this before and had the magic sauce recommend. I will try a few

5/16 is .3125 and 1/4 is .250 so 1/4 would do it.
