Help - looking for a fresh O ring for the tcase input...anyone know this part# and vendor? I’ve searched and just can’t ID a replacement?

Thanks,
Dave

Used to be available at JBG. Don't know if they still are.

Thought we had them too, but I don't see it.
If I'm looking at the correct seal, the part number is either #49302 for one that is 2.627" diameter, or #47583 for the one that is 2.762" diameter.

Seems like that needs a bigger one, so measure yours just to see if it falls into that category.

Thanks guys - the O ring is 4” id. I installed it 9 years ago when I lived in your town Viper. Just thought it should be replaced while I’m “in there”, but current one is smooth and no rotting so I may just re-use it. If I pick one up from Home Depot will it have the same resistance to petroleum products or will they be different material?

I think you'd have to read the details at the point of purchase. Some might be just for water filter housings or something like that, and not be resistant to petroleum.
But I bet they have some that are oil resistant.

Too bad every town doesn't have an "O-Ring Depot" too!

try your local napa.

My search comes up 568-240 Which is 3.734 I.D. by .139 diameter makes 4.012 O.D.

But I can't verify and I haven't bought them.

Have you tried Advance Adapters? You'd think they'd have it since that's one of their adapters.

And they still sell and base a bunch of their adapters for the D20 off that design.
