Hey guys, I found what appears to be a dried out seal inside my heater inlet/outlet pipe. I am wondering if there is a Dorman equivilant for the seal or do I have to purchase the entire assembly from the dealer? The GM PArts east catalog indicates that it'* "part of 4,7" meaning the adapters but purchasing both would run me almost $50.

If I have to get the entire adapter assembly, is there a good aftermarket product for that as well?

What I found:

Take a look at rockauto.com, Dorman part number 47065HP. $6.10 for new aluminum elbows and o-rings.

So I think the Dorman coolant elbow you listed is part #10 in the diagram I have posted.

I am talking about part 6/4 and part 7/4, the heater inlet and outlet

And I know all about the aluminum coolant elbows
