5 of 5 A little tight but that's never a bad thing!!! September 15, 2023
Reviewer: Rumpleicious Brewing from NC  
Had orings starting to leak and deform.  Read from others that these were a tight fit...and they are.  Put outer ring on and pulled outer edges while pushing down to seat.  Seemed that screwing the inner seal onto the post (after you pry it on) works best.  Keep turning until it is realatively close to the kettle walls.  I hand tightened the nut as much as possible and gave it about another turn with a large wrench.
Filled pots up for testing and noticed 1. no leaks even while moving the valve around to simulate usage and 2. MUCH more stable feel to the valve.  Was kinda loose feeling before because the orings are so soft and you cant tighten them much w/o deforming the oring.  I put a fair bit of torque on these and NO deforming!  I ordered extra in case the tight fit causes wear but I'll take that thight fit over leaks on boil day anyday!

5 of 5 Seem very nice, a hair tight. May 16, 2017
Reviewer: Josh G. from Upstate, NY United States  
I bought one to try out, they are well made but are a hair tight on the tapered 1/2" NPT fittings I have. They do fit but they'll probably get torn up after a while. I'm still going to buy more as the seal they make is far better than an o-ring. I'll just be sure to grab some spares.

5 of 5 Great for self build bulkheads. March 31, 2016
Reviewer: John Anderson from Pasadena, TX United States  
Had to build a few irregular bulkheads when installing a recir. loop in my HLT and these fit the bill. They seal up everything just fine.
