I modified both of mine with no problem, I used a 1" hole saw and used a block of wood inside. The spigot screws in with no leaks I highly recommend this

If anyone does modify there keg and by chance screws it up don't throw it away you can use an epoxy putty to repair the keg. My brother gave me his old mr. beer keg because the plastic below the spigot broke(he's not real gentle) had it fixed in a couple of hours and a few cleaning and rinses

It took a long time but I found what I was looking for. This gasket has an inner diameter just under one inch but it still works if you attempt to modify your keg and you have a leak. I ended up finding a couple of leaks on two of my kegs and this gaskets will work great. I picked them up at Home Depot in the plumbing section. Here is the link: Home Depot

think you bought them all AJC16 they are outta stock

I was wondering how these spigots are working for those of you that have made the conversion. I really like the idea. I am thinking about doing it to my 4 fermenters. I do indeed brew a lot. And making the modification would be a real blessing on bottling day. I may have missed mention of a rubber washer for a seal. You do have 1” rubber washer to put on it. Drilling that hope would be breeze. Just would have to get the parts. Anything that makes all of this much easier is just fine with me.

Paul...the one I got from my LHBS had two washers (one for each side).
I have done 6 batches with this mod and it makes bottling day much easier. JMHO

I've done a transfer to a secondary (2nd keg) and a bottling with 2 modified kegs. Everything went well and the beer turned out great.

I would recommend a hose clamp to be used around the hose and spigot. I sprung a leak and mentioned it in a different thread.

I would also recommend that there are no rough edges where the rubber washer contacts the keg. I had to make sure it was nice and clean in order to stop minor leak. I did my modification a little more crudely, using a razor blade and rasp, but she works.

Today I converted all 4 of my Fermenters. I plan to use them next week. At this point they look very promising. I am not sure who came up with this conversion, yet I sure would like to say thank you. You all know what a pain in the butt it has been to have to keep the spigot depressed while you are filling your bottles. I have days that I can bottle 2 or 3 cases back to back. All I need now is a bottling wand, and a short piece of siphon hose. I can get all of that at my Brew Store.

Did your valve come with a nut? I ordered four valves but none came with plastic nuts.

Welcome zzyzx
The spigots I've seen at my LHBS all come with the nuts and gaskets.
