ZF 4HP22E O rings

Would anyone have the correct size for the cooler line O ring into the trans body please?

Mario is getting me some genuine ones but I want to swap one out ASAP.

Cheers.

It’s either BS111 or BS112 - it won’t be metric.

That’s 11.11x2.62 or 12.2x2.62mm

Thanks Mike, that surprises me but I'll try and get one of each.

German “metric” is usually just Imperial Sizing converted.

Go for Viton [emoji41]

I have ERR1594 spares in my garage and measured one with caliper when i saw your post hence my reply so might be some micrones difference but IMO even 11.5 x 2.5 orings should be up to the job

They don’t make them [emoji41]

100% on the Viton.

If I hadn't lost my massive HNBR auto AC kit I'm sure there would've been one in there that fitted, and HNBR is pretty bloody good for temp and mineral/PAG/POE/PAO oil resistance too.

Ouch. Not a cheap kit to lose either.

I did wonder, i've never seen a standard half size metric O ring in a catalogue or kit either, but there's some weird stuff around too.

That's the first hit on my google search: FKM O-ring 11.5 x 2.5mm Minimum 5 pcs - OringsandMore (https://www.oringsandmore.com/fkm-o-ring-11-5-x-2-5mm-minimum-5-pcs/) available all over Europe too but can't see in Australia [bighmmm]

The joys of working out of a ute with boxes not quite big enough to take everything you feel you need.
I would've taken it out while shuffling crap around on site and sat it in the tray.
You can guess the rest.

I'll pop into the engineering supplies/bearing service tomorrow and hit them up for all three sizes.
One will fit! [thumbsupbig]

I want to do a dump and refill plus filter change on the weekend and take an oil sample after losing nearly 6 litres when the fitting came loose last weekend.
