Z32 PWR.STRG.H.P. SENSOR SWITCH O-RINGS

What are the dimensions of the o-rings for this unit ?

 

Assuming I deciphered your bunch of letters correctly.
CZP sells a replacement, "CZP Replacement O-Ring for Power Steering High Pressure Sensor Switch for the Nissan 300ZX Z32. Nissan doesn't sell the O-ring as a separate part so we took measurements of the OEM O-ring taken off of a pressure switch and sourced these identical replacements." maybe they will tell you.

 

Thanks N185. Have already written to CZP - havn't had a reply yet but hoping !

 

You did. I'm impressed, I couldn't make head nor tail of the thread title mate
