Steering rack O-ring kit. Which goes where? Transit 2013

[U-P]

Hi

I have annoying problem with 2013 2.2 d Transit Custom project..

I have a new o-ring kit for power steering rack hoses....

All the rings are different...
Two black with round form (cross-section)
One green with round form (cross-section)
One black with flat form (cross-section)

And I don't have the old ones where to compare.... So....

Which one goes where?

Help!!

There are no clues in the parts diagrams

The colours from google ..
Light Green (HNBR / High-Saturation Nitrile): This is typically used for the high-pressure line connections (e.g., where the pressure hose fits into the power steering pump or steering rack). Light green HNBR rubber is specifically formulated to withstand the intense heat, fluctuating stress, and chemical degradation of synthetic power steering fluid or ATF.

Dark Green (FKM / Viton): Often used for power steering pressure switch/sensor seals or heavy-duty connections. It provides maximum chemical resistance to keep fluid from leaking past electrical sensors

Black (Standard NBR / Nitrile): Typically used on the low-pressure return lines, reservoir connections, or cooling lines. Standard black O-rings are cost-effective for generic sealing but will degrade prematurely if forced into the high-heat, ultra-high-pressure side of the system.

Grey / White Teflon: These are not standard rubber O-rings, but rather rigid Teflon sealing rings. They fit into a specific groove on the metal high-pressure line nut just behind the rubber O-ring to provide a crush-seal backing that locks the high-pressure fitting.

I suppose after the above advice its down to size and fit. and the grey are a rubber substance not stuff as google i think suggests

I put the part number of the kit .. which btw only contains 2 o-rings . into ebay .. and found dark green and light green sets and of black and grey sets

hope the above is of some use as a Guide

n all the best.mark
