Need source for brass fitting

Don't know if this will help or not, G 1/4 with a couple wraps of teflon works fine with 3/8 NPT

Thanks for your reply delluser1

Right now, the oil cooler has 1/2 tygon clamped to the copper tubes, but it's really ugly!


I think I'm gonna try and drill out the male threads on this extention fitting, clean off the finish to bare brass and solder two of them to
the 1/2OD tubes of the oil cooler, then of course paint it all black again.

With the female threads in place, I can then just screw in some 90 degree elbows to point towards
the bottom of the case. I'm working on sleeving & re-wiring the whole case right now, my orders should
arrive tomorrow. Once the wiring is done, I'll order the extensions and post pics of results

Inside the valleys of the G1/4 thread measures .473".
Don't see that working unless you cut off the male threads completely, drill into the female threads and use the extension as a sweat to IP coupling.

Or, I'm all screwed up and that's what you meant.

OP...looks almost identical to an oil cooler I ran for a while before I went with my dual rads. To be honest, adding my dual MCR320's actually cool much better than that oil cooler, and here's why:

Most watercooling rads use thing, oval/thin rectangular tubes in parallel runs down each side of the rad. I'd estimate 8-10 tubes per side of rad, each direction. In those oil coolers, you have a single, 1/2" tube that runs between 6-10 runs throughout the entire cooler. Now, that being said, the tubes inside a radiator have more surface area for the water to contact the walls of the cooler directly, where as the oil cooler has perfectly round tubes; most of the water runs through the middle of the tube. You'd have less surface area for your water to make contact in that oil cooler as it moves through the entire run, vs that of a traditional WC rad.

Don't get me wrong...I like your idea (mostly because I also had one almost identical to that). But, you'll see better performance with other options. You also might want to consider looking inside the tubing of that cooler, mine had a long strip of aluminum inside that was meant to help the flow of oil/coolant...you'll definitely want to remove this...aluminium and copper do not play well in a watercooling environment.

Oil cooler (also a Derale, like yours)


Current rad setup

That's my plan delluser 1, cutting off the male threads should allow me to put the extension in a drill press and drill out a nice tight socket
about 1/4" deep, for the copper tubes to be sweat soldered up & painted black  



Thanks rubix, the aluminum thing will be checked out asap. As far as performance goes, my rig needs to be quiet before all else.
I went to water to get rid of as many fans as possible. My son OCs this rig while gaming on it (multiple BIOS), but it also runs an entertainment
center on a 46" flat screen.
