Dick: here is the part #

Dick,

It is 3M Strip-Calk.The number is 051135-08578 ,I think you just need to provide the last five digits after the dash when ordering , those are the large printed numbers on the box not the first six.I believe it also comes in gray but my stuff is black and is labeled as such on box. I am linking photo. Craig

The "dum-dum" or 3M strip-caulk is not what you want. The moldable tape-like material you want is available at any good auto parts store in a blister-pack in the A/C section, usually called "Cool-Aid Insulation Tape". Or, at any shop that services A/C systems.

There's also....

die-cut foam rubber seals surrounding the evap inlet and outlet pipes to seal the entry of the firewall mounted Harrison air box from invasion of under-hood hot air flow. These are sold separately by Dr. Rebuild and called out as seals 'C' and 'D' in his 68-82 air conditioning seal kit diagram.

You can also 'make' one by pirating a similar foam rubber seal from an A/C equipped scrap yard Chevy pass car of the era and modifying its ID/OD shape with a pair sissors. The pass car foam won't be the exact same shape as Corvette, but once it's press-fit installed around the inlet/outlet pipe, you'll never notice the subtile difference + hand modifications.

Thanks, I checked out Dr Rebuild's catalog and it looks like the right stuff.

Better Take A Look At...

John Hinckley's post below, Dick. Unless I have totally misunderstood what you are asking about, that material is NOT a sealant like 3M Strip Calk although it may look like that product. It's an insulation wrap provided to insure the capiliary tube to the expansion valve is getting an good reading on the evaporator tube temperature. John gave you an specialty product name, and I gave you a source for NOS; ball's in your court.

Re: Better Take A Look At...

Chuck I think you got it right. Reading Dr Rebuilds description and looking at the ASM I think it is the tape that wraps around the top tube and the expansion valve sensor. I had previously replaced all the other seals on the evaporator.
