is this spit size 5/16, 3/8, or 1/2 inch?

5/16". I'll finish my rating by saying that Char Broil did replace the entire rotisserie attachment. Motor, mounts, rod and all. It does take several phone calls and the copying of 3 year warranty off the side of the box and sending it to them (email). It would seem that they are unaware of the 3 year warranty on the box and the first four calls I was told that there was a 30 day warranty and that was only if I had purchased it from Char Broil direct. On the fifth call I was sent to a supervisor who had me send the copy of the 3 year warranty off the box again and I had a new rotisserie within a week. If your having problems with something from Char Broil be persistent. It seems they have a script to work from and you don't get kicked upstairs until they decide that you're not going away.

Mine that I bought is 3 3/16". It fits my Kitchen Aid blender perfectly and it works great. I hope that helps.

5/8". If that works for you I have the 2 I opened that I can not use or return.

I think its 5/8 The end is tapered and rubber so it fits in the aqua stop valve for the Canister. Only reason I bought this one was to relocate my canister. Other wise it's pretty useless to hook up anything else.

Mine was 3/4" and it fit beautifully. There are also fittings that will adapt to several different diameters, as mentioned previously.

I've measured it at 2 9/16" OD and 1 15/16" ID with 1/8" thickness. This is for the 3-cup gaskets. (edited, because I realized Amazon wasn't associating this with the product I actually purchased)

The nipple is 3/16 bore. I've managed to fit a 1/4" vinyl line on, but a 3/8" fits nice.

Sorry I didn't see this until today. The smaller part is 1-15/16" the larger end is 2-1/8". Useful for almost any little coffee maker filter.

1.5" is the ID of the pipe so you insert that on the inside and the 2" is the OD of fitting so it fits over the outside of the opening. Therefore it works for both size pipe dimensions.

This is not 5/8 inch or 0.710 as in first question. It is 6/8" = 3/4" = 0.750 inch, I had order three of them and had to return because they were too big.

It will fit either size, it has an adapter sleeve in it to fit the 1/2 or remove it to fit 5/8 Mike G.

Sorry.. It was quite sometime ago I purchased this. I don't really remember if it was 5/8" OD or ID.

The actual size is .5" from outside thread to outside thread. So it is indeed the 1/2".

JC, I measured it before responding to your original post. Mine measures exactly 1/2"

I would use 3/8". You will need to purchase a barbed tube fitting 3/8" tube x 1/2 npt
