march pump quick disconnect
 
Tried to search through some forums but couldn't find a direct answer. I am trying to finish up my pump disconnects but can't figure out what quick disconnect to put on the "in" side of the pump since it needs a 1/2" female connector. I have a ball valve on the "out" side so putting a quick disconnect on it was easy. Does anyone know the part number for the female 1/2" connector at McMaster Carr or for the poly high temp quick disconnects or am I just missing something very simple in all this. Thanks for the help...

Just use a 1/2" coupling with female ends on both sides between the QD and the pump.

Thanks. I figured it would be something easy I was missing. My brain must not have been working late at night.

Most of us use male qd's on all the equipment....then have a female on either end of the tubing. Works great....and it's cheaper to buy lots of male qd's vs. female.

I had the same thing happen to me when I was looking for parts until it hit me that I overlooked something simple, so it wasn't just you :)

I just settled on using QDs on the kettle and mash tun, and used Blichmann QuickConnectors on the ends connecting to the pump since I'll never be in a rush to change hoses on the pump itself in my setup. I will need to swap lines on the kettle and mash tun fairly quickly (and metal connectors would be hot at the time) so I used the polysulfone QDs on those.

The only reason I put QDs on the pump end of the hoses is so I can disconnect and do an oxyclean soak. The outside of the tubing gets sticky too after a few batches.

I wanna see some close ups of some good QDs o a march pump here if possible please. Just for a good reference for the future. Not just equipment porn for me, honest. :)

it's not at the march pump, because I don't need to spend another $40 for QD's when I can just slip the hose on and off the barbs at the pump easily. But at the recirc arm of my whirlpool IC, I did put one, so that I can quickly disconnect it and re-route it to the fermenter once the wort is at pitching temp. This is the polysulfone (CPC) model. Works great in water tests so far, will put it into its first real brew action tomorrow.

Ah!! Thanks evan!(!) just as I suspected, everyone is gonna have a different looking thingy. So I guess I just gotta look and see what is in my local area. :)

I use the male and female brass Quick Disconnects from McMaster. I've selected the 90deg female QD as this helps reduce any kinking. Here are the part numbers:

6739K59: http://www.mcmaster.com/nav/enter.asp?partnum=6739K59

My connection to pump (1/2" ball valve on pump, 1/2" full coupler on input side):
