What's the 250z probe oring size?

Not seeing the probe on the exploded views I have...

Just had to replace mine. Had to search thru all the o-rings to find one that fit and didn't blow out. Didn't measure it so I'm not much help. The drawing and parts list aren't very helpful either.

I believe it has the o ring on or in the intake sleeve or thimble,, #17 5.5x1.5 #18 10x1.5.

Trouble I'm having, is where ever I remove the barrel assembly I find the the large O-rings were softer and swelled enough, that they wouldn't go back into the action block. I'm using Silicone grease on them when replacing them. These are the O-rings I purchased from Barra.

I wish there was a much clearer Diagram of the parts. Try this.

Got a response from Barra. 1.5mm x 4.5mm.

There are no 4.5mm orings on that chart.
