Mcmaster's pages are not linkable, search for:

6739K59
Straight Through Coolant Hose Coupling Plug, 1/2" NPTF Male, 3/8" Coupling Size
In stock at $1.75 Each

6739K64
Straight Through Coolant Hose Coupling Sleeve-Lck Sckt X Barb for 1/2" Hose ID, 3/8" Cplg Sz
In stock at $6.01 Each


If you're into all stainless and higher flow (the nipples have 1/2" ID instead of 3/8" like the ones above:

6543K45
High Flow Straight Through Hose Coupling 303 SS Plug, 1/2" NPTF Male, 1/2" Coupling Size
In stock at $20.63 Each

6543K35
High Flow Straight Through Hose Coupling 303 SS Sleeve-Lck Socket, 1/2" NPTF Fem, 1/2" Cplg Sz
In stock at $44.57 Each

Way too pricey for those though.

These are what I used in my system

6739K59 1/2" NPTF male pipe thread coolant hose quick disconnect 1.75(Page 277) #3
6739K64 1/2" NPTF female coolant hose quick disconnect (straight) 6.01 (Page 277) #1
6739K68 1/2" NPTF female coolant hose quick disconnect (90 degree) 7.44 (page 277) #1

Just go to McMaster.com and put in the part number in the search, that'll get you to the right page.

I've bought both the 673K59 and 673K64 QDs as well. It is the connection between the kettle and the T in Lonnie's Brutus 10 I'm trying to solve. (Lonnie went with female QDs on the kettle and I went the reverse with the female QDs on the hoses.) I need a male 1/2" NPT into the kettle and T and this stainless fits the bill perfectly other than the cost. A brass alternative should be in the ten buck range if I could find one.

Look for Pressure Washing Suppliers. We use those things daily in steel, brass, and SS. Available in 1/4, 3/8, and 1/2". We use Viton O rings for 220°F at 300psi, so they should suffice for any beer service.

Budget QC's at PressureTek
Budget in SS
Budget in brass


Better quality QC's at PressureTek
Better in SS
Better in Brass

Yes, but they are less commonly available. Ask for a Double Shut Off QC.

$10.00?!?. I'd keep looking or adapt down to 3/8". A 3/8" female brass QC will only cost cost you about $2 in brass and $3.75 in stainless.

Does anyone know whether McMaster part no 6543K45 would be compatible with the Morebeer quick disconnects linked above? I bought some from Morebeer and I need some more. They sure look like the high flow couplings. But Morebeer says they are 304 SS not 303.

I need to replace the o-ring in one of my disconnect sleeves. Anyone got an idea where to order them? I didn't see any specific information on McMaster's website, but I may give them a call.

Lil' Sparky, those disconnects from MC are compatible with Parker Moldmate series. You might check with Parker (I found them via google) to see if replacement o-rings are available. I bet they are.

Meanwhile, can anyone tell me if the barb fitting at the back of the female disconnects can be removed? For example, on 6739K64 1/2" NPTF female coolant hose quick disconnect (straight), is it possible to unscrew the barb off of the disconnect? And is it 1/2 inch NPT or NPTF if so?

Finally, has anyone tried using the high flow parts like these? The plugs and the sockets come in male and female genders so you can adapt easily to whatever you have, male or female NPT fittings, without additional connectors. You can add the brass barbs. It works out to be about twice as expensive as the other fittings that everyone is using, but it has some advantages. They seals are Buna-N and are only rated to 250 degrees, not as good as the silicone seals in the coolant disconnects, but still usable.

5346K25 Brass Barbed Hose Fitting Barb X Male Pipe for 1/2" Hose ID, 1/2" Pipe
6537K93 High Flow Straight Through Hose Coupling Brass Plug, 1/2" NPTF Male, 1/2" Coupling Size
6537K13 High Flow Straight Through Hose Coupling Brass Plug, 1/2" NPTF Female, 1/2" Coupling Size
6537K65 High Flow Straight Through Hose Coupling Brass Sleeve-Lck Socket, 1/2" NPTF Male, 1/2" Cplg Sz
6537K75 High Flow Straight Through Hose Coupling Brass Sleeve-Lck Socket, 1/2" NPTF Fem, 1/2" Cplg Sz

I have never tried unthreading the barbs but I THINK the do come out. Sparky, have you tried a keg post Oring in the fitting? I have some #111 rings in silicone if the size is right.

A note on the high flow thing... I don't know of any operation in brewing that requires such a high flow. Liquid moves so fast that I usually have to throttle it back. During chilling, the CFC/Plate chiller is always going to be the restrictive point. Get the cheaper QDs.
