radiator o'ring

Hi, I just finished installing the radiator of my 1995 ext. cab 5.7 truck. I took it to correct a leak & flush. While connecting the lines from the engine oil cooler I realized that when I disconnected they were worn out, so I had to install the lines with out a flat o ring, I should say that one of them doesnt leak, but the other does. I went to local parts store and said dont have it. Does anyone know a manufacturer and part number. I tried to find then in the doorman products page, but couldnt seem to find it. Would appreciate any help.

I would bring the o-ring from the other line into the parts store and match something up.

Most parts stores sell an o-ring kit that contains various sizes for pretty cheap. I am putting a new engine in my truck and that's what I am going to pickup. Otherwise I think that Rock Auto has them onlide for $.75 plus shipping.

thanks for reply, yes I have seen this kits, but the problem is that they are round o rings, the o rings on my truck are flat. I tried the round ones, but when thighting the line nut, they get damaged and fail.

I agree with bringing the one you have to your local autozone, these are pretty cheap....
