So I came across some money to spend and I'm ready to order a pump. I know what to buy there, but I also want to try to cover all the QD's that I'll need. Here are my thoughts:

Male QD straight through coupling insert, 1/2" MPT, (Item #60796), permanently attached - 7 total:

BK out
CFC in
MLT out
Pump in
Pump out
HERMS in (future)
HERMS out (future)

Hoses w/ female QD straight through hose barb bodies (Item #60674) on both ends - 4 total (8 QD's)

Does this look reasonable, or am I missing an insert or two or are 4 hoses not enough? Also, what is the proper hose to buy for the hose assemblies? Is Norprene the good stuff I recall people talking about? $2.89/ft seems awfully expensive. This silicone tubing would be much easier on the wallet at $1.10/ft. I assume it would also be acceptable?

I realize this stuff has all been asked before, but when I searched I got a bunch of threads that talked about all kinds of different stuff, so I wanted to try to catch it in one thread.

Your estimate seems good to me, Mike. I would use reinforced vinyl tubing for everything but the hoses from the kettle to the pump and on to the chiller. For those I would use silicone; the Norprene tubing is very nice but overkill. I've never had any problem with the braided vinyl seriously deforming at mash temperatures. As I see it, that means you could use two reinforced vinyl hoses and two of silicone.

At least that's how I see it. However, as Dan L. says, I could be all wet.

Make sure you get the polysulfone QD's because of the higher temp rating. Also I think it best to avoid the QD's with shutoffs as they restrict the flow with a pump. Think I remember that from Moving Brews info. Some of the fittings will have a X in the opening that most folks cut out to avoid getting grain or hops particles caught in them and restricting the flow.

They're not cheap but you will be happy you have them.

Good call Bill, saves even more money. Thanks!

Vance, the item #'s that I referred to are the polysulfone ones, I remembered those conversations.

I would recommend thicker-walled silicone tubing. I use 1/2" ID, 3/4" OD which works well. Tom

Mike,

Think carefully about your hoses. You probably don't want a QD directly attached to the pump. Instead, the pump has barb fittings attached, which connect to the hoses. Then, at the end of the hoses, you put FEMALE(qd end) x BARBED (hose end) QDs (shutoff QDs here are nice).

So all of your vessels have male qd X male pipe thread, and the two hoses for the pump terminate in female QDs.

Don't forget chiller hookups, which means at least one more male qd X [whatever you do to attach to the chiller input].

Just be absolutely sure you get all the connections figured out perfectly before you order. Then order one extra of each kind.

Joseph, let me make sure I'm following you here regarding your first paragraph. You are saying instead of having male QD inserts attached to the pump, you would use regular hose barbs and permanently attach hoses to the inlet and the outlet of the pump with female QD's at each end? I guess that makes sense, but if you use shutoff QD's at the end of the hoses how do you prime the pump? There isn't anywhere for the air to go? Or would you use a diverter valve of some sort at the pump exit instead of just a regular ball valve?

RE: your second paragraph - that was my plan.

RE: your third paragraph - I listed the CFC input under my list of male QD x MPT connectors.

Good, one of the links you posted had the specs for polyproplene and polysulfone QD's.

Also I found some descrepancies between the USP website and their catelog with the part #'s when I got ready to order. I called them to place the order to make sure I got the right things. Don't remember which place was right or wrong. And after counting and counting again I came up one fitting short.

The only input I can offer is to use the reinforced tubing. On my system I tend to run into problems where the tubing gets warm and flexible and kinks - restricting flow. Also - order more than you think you need. Unless you have the perfect layout (which I don't yet) you end up bending the hoses more than you'd like which can make kinking worse. Of course, that said, the more hose you have, the more head loss you have and more wort left in the system (and this also affects dough-in volumes).

I think I understand what Joe is getting at...it's an interesting idea.

Will do Elk. I'm going to get it all from either B3 or NB, because once I tallied up all the connectors at USP the shipping was going to be $22, which ate up all the savings on the price of the parts. I'll probably order from NB because the pump is a wee bit cheaper than at B3 and shipping from the Twin Cities to here is cheap. After I order I'll post the list.

I ordered from NB. Here is the list:

Qty 1 P/N 7351 - March 809-PL-HS Pump
Qty 8 P/N P016 - CPC Fem Disc 1/2" Barb
Qty 7 P/N P017 - CPC Male Disc 1/2" MPT
Qty 10 P/N 7128 - 1/2" Thermoplastic Tubing

They don't carry silicone tubing so I got the high-temp thermoplastic instead. I bought 7 male disconnects so even if I don't use them on the pump I will have a couple to use elsewhere in the future. They are the cheap part of the QD's anyway.

Total with shipping to eastern WI: *gulp* ~$285. B3 would have been about $295.

*edited to add NB part numbers*

Joseph,
My pump has threads on it to which I have used couplers to screw in the male QD's. Are you saying I should replace this with barb fittings? If so, why? I really want to disconnect these fittings between brew sessions to allow the interior of the tubing to air dry.

Also, I have read here that I need to remove the X inside the QD's. What is the best method to accomplish this? I have concerns that should I not get a good clean cut it would be a place to harbor gunk and bacteria.

Thanks.

Well you do plan on cleaning after you brew, right? :-) Regardless, this area will be cleaned of bacteria during recirculation. And if that doesn't do the job, pumping 200F wort through will.

This is the first I've heard about removing the X inside the QD. Must investigate...

Elk, I only ordered 10' of that hose because I only plan on using it for the boiling temp transfers. That will give me two 5' hoses. I plan on making the other hoses (MLT exit,etc) out of the braided vinyl stuff that I buy locally. I hope it's enough for two hoses, otherwise I guess I'll have an excuse for another order.
