I have a New Holland with a 665TL loader on it that I am having issues getting the hydraulic connections to stop leaking hydraulic oil. I have tried both SAE (A111 7/16"X5/8"X3/32") and Metric (P11 10.8 X 2.4mm) O-rings in them but they always seem to leak. I attempted to look on the New Holland parts website to see if I was using the incorrect size but from what I can tell it does not show the O-rings just the hydraulic lines. The coupler says "Made in Italy" on them and I assume this type of connection is used in multiple applications across the CNH lineup. So anyone on here have any experience in getting these to now leak? Thanks!
