Kubota LA463 quick connect O ring and backup ring size and availabilty?

[Ampped]

I need to get replacement o rings and backup rings for the quick connects on my Kubota LA463. I could only find one thread that referenced durometer of the o rings but not size. I cannot verify brand of the connector but the number on it is hnv38nptf-09n0 and made in Italy. I can "match" the size at the local parts store for the o ring but they don't have the plastic backup ring. I know I could probably make the trek to the Kubota dealer but I'd like an aftermarket solution as I seem to loose these occasionally when disconnecting the loader. Any help finding these online or a cross reference for a part number that I might find locally would be greatly appreciated. Thanks!

Any advice on finding these online or otherwise would be appreciated. Thanks!

The only ones I know of made in Italy are stucchi

Those are Faster quick connects. Made in Italy.

Any hydraulic shop should be able to help you with the O-rings and backing rings going with just the size.

Thank you for the link. Those appear to be correct. Two questions: What order does the backup ring and o ring install? O ring closer to fitting end or vise versa? Is there a single seal that replaces both?

I was just looking exactly at the female quick connects on my loader the other day and for the life of me I can't remember the order now. I'm pretty sure it's the backup ring first, then the O-ring. Maybe you can look at the others ones to compare.

I'll take a look one of these days, if the rain finally stops that is.

Anyways, found this close up picture:
