1 of 5 poor thread count May 5, 2021
Reviewer: Mike from BC  
I fount the 3/4 NPT eternal threads to work on about 50% of the ones I ordered. The ones that did not work could not thread onto any other 3/4 NPT fitting I have, and I have a lot! I made do by going out to the local plumbing supply and buying a cheap brass equivalent. Won't be buying any more.

2 of 5 Only good for light duty upper ports October 25, 2020
Reviewer: Jake Stinn from Lake Country  
Like said in another review, this would work better if the nut had a larger contact surface and was grooved. I used one on my HLT recirculation port and its quite temperamental to get to the right tightness to not wobble around. For that reason I will not use this on lower ports.

I have already bought 2 more I was going to use on the outlet of my mash tun and for a thermometer on my boil kettle, but I will be using a 1/2" Male NPT close nipple with a grooved nut and o-ring instead and selling these.

2 of 5 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

5 of 5 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.
