McMaster-Carr, p/n 71445T84

I just looked it up and was wrong. Max operating temp is 300.

wow I was thinking of making a top manifold out of copper 1/2 inch. with a connector in at one end in middle where my hot water can just flow with a bunch of holes under for the sparge arm. almost like a manifold home built but for the top on a rectangular cooler sit on top.

Man, I just hooked up a barbed fitting to the end of a street elbow through the lid. On the end of the barb (pointing down into the MLT), I have either a short piece of tubing hooked up to a siphon sprayer for 10 gal batches, or a long piece of tubing hooked up to a siphon sprayer for 5 gal batches. Total outlay for the siphon sprayer was $2? Including the rest of the hardware, maybe total out of pocket was $12?

I like the copper tubing approach.

I almost went down the rotating arm build but decided on simplicity. I figured pointing the holes up would prevent channels from formaing. The only drawback in this design so far is if I open the pump valve too high. The wort splashes off the inside of the cooler lid and leaks down the outside.

The tubing I had was too big for the copper so I just clamped down with a stainless hose clamp. To stop up the end I just pinched it with pilars and folded over.
really liking this cheap DIY for fly sparging. You said you thought you drilled too many holes. What do you think the optimal number or distance between holes should be?

*edit* just realized this was over a year old. Hopefully, he's still around
