Review on 🍺 OneBom Weldless Bulkhead Fitting Brewing: Durable and Efficient Solution for Brewing Enthusiasts by Jim Bethea

That would be a good product at a good price. 5 star rating. But unfortunately the seller carelessly chose the wrong set of rivets for this product. As you can clearly see in the picture, the fitting is stamped "1/2 x 12". That means the NPT thread is 1/2" (good) and the burr is 12mm (bad). If you put a 1/2" pipe on it, it will just fall off. 1/2" = 12.7mm, so it's not surprising that a 12mm router won't work with 1/2" tubing, which is what most people will use in their homebrew setups. When I contacted the seller they tried to tell me that the size was correct and that I should use a clamp to hold the hose! I tried to explain again (which must have been an obvious mistake on their part) and then they said to try a smaller pipe! So the product is wrong and the seller doesn't want to fix it. All the makings of a solid 1 star rating. Too bad. Recommend buying from someone else.
