HN TS100A hydraulic o-ring and washer install

[Jamie McAdams]

This is my first time on this forum. I need to install new o-rings on the hydraulic quick connects on my NH TS100A and I'm not sure about the order in which the washer and o-rings go. Does the o-ring go in first and the washer acts as a retention ring? The washer and o-ring look like the one in the pic.

O-ring is towards the pressure side, back-up ring goes towards low pressure side. This allows the O-ring to seal and the back-up prevents the seal from extruding

Makes sense. Thank you.
