So I'm sitting here trying to figure out what parts I need to connect my 30' 1/2" HERMS coil to my HLT. I have 1/2" SS couplers welded into place, so should I be using a 1/2" CxM Copper union?

A couple of pictures would help. But you can go many different ways, hard pipe to soft or start off with soft. Union's yes if you want to take it a part. Dominus VobiscumSwagman :lol:

It kind of sounds to me we want to connect the coil to the HLT? Usually you just put the coil in the tank. Need more info.On mine, I run a 1/2 ID hose from my pump to the coil, the out the coil to the MLT. On the coil I sweated 1/2-inch female pipe fittings, and use Swag's tri-clovers.

Oh, I get it now. You already have the couplers installed? Otherwise, I'd suggest making it like an immersion chiller and just come up the top. $0.02.

Hey Swagman -Are you still selling those tri-clovers? If so, you might want to post in the new classifieds. Someday, when I finally get around to building that dream system that we all have in the back of our heads, I'd like to go tri-clover thoughout.sorry for the hijack, too.

Looks to me like that would work fine. You priced unions recently, though. *whew*

In 1/2" the CxM are $5.91. The CxC are $3.39. The CxF are $7.48.I'm going to use CxC w/ my bazooka T in my boil kettle and the CxM in the HLT for the HERMS coil.

I like the idea of a union so that you can easily remove the coil. My HERMS coil uses compression fittings with o-rings instead of the brass compression ring. It makes it easy to remove to clean either the keg or the outside of the coil. Yes, I know that theoretically you should not need to remove it, but I seem to always find a way to make it necessary. Usually through some screw up on my part.

I was planning to just use 1/2" MPT to 1/2" compression fitting adapters.Although the idea of soldering a union on would probably make removal a bit easier.

Not Swag, but those look like "my" QD's which are called 'Brass Coolant Hose Couplings.' Male connectors (p/n 6739K59) and female hose connectors (p/n 6739K64).

+1.If your coil is soft copper use a 1/2" MPT to 1/2" compression fitting. They're just as easy, if not easier to remove than unions. Probably more expensive, but the better solution IMO. I prefer Swagelok (or the McMaster version 'Yor-Lok'). Looks like it's $8.26 for brass (5272K199) and $17.49 for stainless (5182K135). Either one will work with the copper tubing.

I have the full couplers welded to the keg and attach HERMS with a 1/2" male adapter. The HERMS itself is soldered to the adapter so no removing it unless I de-solder the fittings. Hopefully I wont have to but you never know.
