Aftercooler pressure tester

[worldcatlemon]

So after cleaning the aftercooler core I wanted to pressure test it for leaks before assembling the aftercooler. I saw a picture of the way Seaboard tests them but I wanted something I could hook up quickly since I have 2 aftercoolers to test.

I thought I would share my cheap and easy design . ABS 4″ pipe with a 5″x4″ reducer, end caps, with one end tapped with a female air fitting and valve so I can regulate the air pressure.

It took about 20 minutes to build but I can look for leaks before going through the process of reassembly.

Rubber reducer is 5″ ID on one end and 4″ID on the other. Rubber reducer doesn’t touch the fins but seals on the outer copper ring and seals on the ABS.

I understand now forgot about the core-ring. What size is the rubber coupling?

Thanks for sharing.

Looks great. What does the end of the core seal against up end the rubber pipe coupling, also coupling size? The outer rubber does not clampdown tight are it would damage the fins correct and not seal?

I Like it–in fact I like it a lot if it works and the ends do not side of at 20 PSI or so…

Thanks for sharing..
