I need to order disconnects. I already oredered 1/2" ID silicone hoses. I was looking at #'s 6739k68 and 6739k59, are those going to create a restriction in flow? It looks like I will be choking down the 1/2" ID line.
Mcmaster Disconnect ?

Meh, I use those. You won't get 100% flow, but for 5 and 10 gallon batches their fine for me. My march pumps prime and work fine with them as well.

Whirlpooling is similar to snipe hunting. Actually I don't whirlpool, so I can't answer it.
I see no reason you couldn't, it still has decent flow.

I can and do every time I brew.

Cam Locks will give you better flow and hell yeah they whirlpool.

Cam Locks aren't in the budget. As long as the mcmaster disconnects can whirlpool well I will be happy. I ordered a pump so that I could whirlpool and so I didn't have to carry buckets of hot liquids.

Aren't those brass? You could go with aluminum Cam Locks for almost the same price.
Actaully, that 6739k68 is 8 bucks per?!?!? You would save money going with Aluminum Cam Locks.

Before you order, look into the Street Elbow option. I don't suggest the Cam Locks with hose barbs.

I was just looking at those and I just don't understand what parts I would need. What pieces would keep everything at least 1/2" ID? When you remove a camlock does the flow get stopped like with a disconnect? I'm lost, I have never used a camlock or disconnect.
The Mcmaster QD's you posted do not have a valve and the flow will not stop when you disconnect them unless you have a seperate (ball) valve.

No the flow does not stop. You attach them to ball valves.
Type B for the Female end. That attaches to a Street Elbow. I grind down the other threads on the elbow and slip the hose over the now smooth 'threads'.
For the Male it is type A or F depending on what you are putting it on.

Thank you! I just watched bobbys video, that helped alot too. I forgot that I would have valves to stop the flow, duh.

I think I could put the short nipples in my mini lathe and turn them down real easy. I wish you guys would stop changing my plans on me, I'm never going to finish this project
bargianfittings.com has the stainless for 3-6 bucks a piece, depending on which fitting. And super fast shipping (I order last friday and had them at my door this monday). and 5 dollars flat shipping.

I poached that picture. I do have have clamps on mine although I don't think they are necessary. I bought some so I used them. Some guys don't though.
This is where you can get the 1/2" NPT camlocks from Proflow Dynamics:
http://store.proflowdynamics.com/modules/store/-Couplings-for-Homebrewers-_C12074.cfm
These are all stainless, which are preferable to aluminum for easier cleanability. I was able to get everything I needed for $60 for my full all-grain system. At the moment, morebeer has the 1/2" street elbows in brass for cheap in their clearance section, so that's a possibility. I have also recently found that Home Depot carries Lead-free brass 1/2" NPT ball valves for $7.50 apiece. If you're on a budget then those are some ways to go easier on the pocket book.
You'll then need some silicone o-rings instead of the ones they come with. McMaster-Carr has them with part #: 9396K31. It's a pack of 50, but you can use these o-rings in conjunction with a lot of the weldless fittings out there as well, so it's nice to have backups.

I have to give a thumbs up to proflow, I ordered the camlocks the morning of the 26th. I forgot to order the food grade gaskets so I called them later that afternoon and even though the package was ready to be shipped they opened it and added them for me. I got the package in the mail yesterday, it was less than 2 days for regular shipping. These things are really cool and I can't wait to use them.

Their hose barbs look nearly full port - are they? Those might be nicer than the bargain fittings version. Can you tell if these are interchangeable with the ones provided by BF?

I'm 95% done with my single tier and I'm doing a test run with just cold water. I bought the wrong size clamps and have the silicone hose showed over the stainless street elbow threads. So far it's working without any leaks. I know others do this, does it seem to hold when using hot water? I'm a little nervous trying it with hot water.
I don't actually know, but I am using a setup identical to BobbyM's where you use a street elbow with a male NPT camlock and use the threaded end as the barbs. In fact, I put a ball valve on one end of each hose so I am guaranteed always to have a shutoff, not matter what I'm doing.
The only time you need a clamp is post pump where you might forget to open a downstream valve. Without any backpressure, it won't leak at all.
The pics of the barbed version are misleading. I don't know where that pic came from but NONE of the camlocks I've ever seen have a barb that is as big as that picture suggests. Nope, they are all less than 3/8" ID.

You are correct, I could see the water wind it's way up the threads whenever I closed the valve or created significant back pressure. It's not bad though, usually just a drip. I'm going to find some clamps today.
I ran the system this morning with hot water and a small amount of grain to see if everything works with a homemade false bottom made from a colander. It seemed to work ok and should be much better with a full grain bill. I love having the pump and the camlocks are extremely cool.
