L322 4.4 m62 gearbox cooler o rings

Morning , does anyone know what the size o rings on the trans cooler Hose push fit connectors , got leak on fitting , I’ve watched YouTube vid but his measurement were vague , thanks Johnny

Assuming that they’re a standard metric size, I would say that the two O-rings on each pipe are ‘113’ size i.e. with a cross-sectional diameter of ø2.62 and an I/D of ø13.94. The pipe from the cooler has an O/D of ø14.2. The two O-rings each have a back-up ring and, in addition, there’s a formed seal at the end.
