Question about some barbs

Stiffler · 01-23-2004, 12:45 AM

This Swiftech block as 1/2" barbs:

Does that mean my flow is limited to 1/4" or 3/8"? I heard that's how it works. If this is true, then my entire 1/2" setup is being very limited...

Resistances are additive, so every little bit helps. My suggestion would be to use a nylon 5/8" barb on the outlet and try something like this:

for the inlet. Might be counterintuitive to add a restriction to improve performance, but it will substantially increase turbulence where you want it.

So I just got the block in the mail, and I found that the barbs are not permenantly on there, and that they are 1/2" OD barbs. So, couldn't I go to the hardware store and get 3/4" OD barbs, which should be 1/2"ID, and that would significantly increase my performance?

I got 3/4"OD barbs for all my fittings and 5/8"OD tubing. This will give me 1/2" flow through out my entire system. Will the block be able to handle this? Also, the instructions that came with the pump said to never use teflon to seal the threads, but instead to use silicon. What exactly should I use? I don't want to seal the threads permanently, just create a leakproof seal.

One more question. I got steel barbs and am using a heatercore from a Ford with a Swiftech block. The heatercore is most likely a brass/aluminum mix. What kind of additive should I use since I'm mixing all these different metals?
