Seeking O-Ring Specs for Trans Cooler-to-Heat Exchnger Quick Connect Fitting

[SCurley]

Gents/Ladies -
I have a 2005, 3500SRW 4x4, Quad Cab, with 48RE trans. There's a leak at the quick connect/disconnect fitting between trans cooler flex line and the trans cooler heat exchanger. Hard lines and flex lines are fine. Just want to swap in new O-rings inside the QD fittings. Anyone know spec's and/or part # for those o-rings?

The parts catalog does not list them separate. I guess you get them free with a $200 hose. I would try a good Napa store.

Sag2, Thanks for taking the time to check. If no one else has already pulled one and measured/matched to an existing Dorman/NAPA/Dodge part#, I'll do it.

My 2003 kept leaking in -0 temps I removed it went to My O-Ring kit Nitrile 70/90 and Viton and replace it leak fixed, that was 10 Years ago, the factory buna will leak-0

Viton Your best O-ring for that fitting. Napa may have it otherwise its Hercules or Seal masters once you know the size or send it to Me and I will match it up for free.
