I'm doing a build and looking at the best way to put a valve on the outside of a pot, so I need a bulkhead. I would also like it to be cheap.

Is there a less expensive way to get a short straight piece of threaded pipe and two locknuts & gaskets other than site sponsors/retail etc ?

Or another solution that works well that I haven't thought of?


For one of them (where a female thread is preferable to a male thread (return to the top of the pot for whirlpooling) I'm thinking I will try using:

I haven't found the silicon o-rings yet (any links?)

Dont know if you have looked, but HERE.
Nev
I've sourced and made up a few of these and $18.95 + postage is a very good price. Other plus of going with someone like Nev (or other site sponsor) is he's a trusted source so you know what you are buying is what you want/need. I've had some problems with plumbing parts of ebay before.

If you're not 100% sure you know what you are doing, the Gryphon Brewing bulkhead fitting will do you. looks good.
Otherwise a 1/2 inch BSP nipple, 2 x 1/2 inch BSP washers, 1/2 inch BSP locknut, and you can make a couple of washers from silicon bakeware. Drill a hole and tighten up.
If you add up the cost for the above bits and pieces, the Gryphon Brewing bulkhead looks a goer.

Try a 1/2" in compression fitting with 1/2" BSP thread and your choice of copper or stainless tube.
clever. does it matter what the compression fitting is made from?

nice

any idea on whether those fittings would work?
I've never tried that way, my concern would be there is not enough of the male thread sticking out to be useful. All mine have a length of 1/2" threaded pipe with a nut either side of the pot's wall. I've got some detail on my website qldkev.net under howto and fit a tap.

Oh, I think the 1/2" is the female inside, the outside is 3/4". So - use a male-male connector / threaded 1/2" elbow for pickup inside the pot?

I have used the ones from gryphon brewing, and its fantastic. Have a look at the ball valves they are cheaper then other places and you can combine postage :)
