Not a great design... October 11, 2017
Reviewer: Justin A. from Guelph, ON  
The lock nut in this package is not grooved to hold the silicone o-ring nor does it have a large surface area, nor is a washer provided. As such it is a very delicate balance to tighten this without the o-ring being pushed out. Once this balance has been achieved, you may find this bulk head provides less support than what you had hoped since it can not be tightened very much. A second o-ring provides some leak insurance on the outside of the vessel, but shouldn't be necessary if the design were more reliable. If possible I suggest you trying to use a close nipple threaded into a ball valve (or whatever) with a grooved lock-nut and o-ring on the inside of your vessel, which should work a lot better. Lastly, I may be wrong, but at the time of writing this I think it's actually cheaper to buy the individual components here -
3/4" MPT x 1/2" FPT Reducer Bushing
3/4" NPT Lock Nut
Silicone O-Ring

Great bulkhead June 13, 2014
Reviewer: Adrian McManus from Hamilton, ON Canada  
I used this to finally replace the last piece of brass on my cooler mash tun. I already had a 1-1/8" hole drilled though it so the other weldless bulkheads sold by OBK left too much of a space. I got away with this one, even though it is designed for a 1" hole.

Excellent product April 22, 2014
Reviewer: Lorant Marton from Calgary, AB Canada  
This product fits a 1" diameter hole perfectly. it provides internal threads so you can fit an internal attachment and an external attachment.

I had a situation where I acquired two kegs that already had 1" holes drilled into it.
