Description
 
These 304 SS hex nipples are machined out of hex bar stock rather than cast blanks. The result is a much smoother fit and finish including the interior bore which is more sanitary than our budget cast hex nipples. We also cut our threads at a slightly smaller diameter than the NPT standard specifies which allows for a more full meshing with the female threaded counterparts. This exposes less internal threads to your liquid flow and overall makes for a more compact assembly once everything is threaded together. Please be aware that due to this undersizing of the tapered threads, the fit in SOME female threaded fittings may be a touch looser than you would expect where the hex makes contact with the female fitting just prior to the threads tightly meshing. In those cases, sealing will require one or two extra wraps of teflon tape than you would typically use on standard NPT fittings but it WILL seal. This occasional loose fit is a compromise in the design and not considered a defect. It is also possible to roll an oring down the threads to sit on the hex to provide a gasketed seal to the adjacent female threaded fitting if you would like to make these connections seal "hand tight" for regular cleaning break down.

Lastly, the end surfaces are broad and smooth which is important if you plan to use the Blichmann style hose QDs on them.

Not For Mounting Ball Valves January 30, 2019
Reviewer: Greg from Palm City, FL United States  
Because the threads were undersized, they wouldn't tighten enough to secure the ball valve in the proper position before bottoming out on the hex head. I used tons of teflon to eventually get it fairly tight but over time they all loosened again. As advertised, the finish is good and they do seal fine with enough teflon tape. Just be aware that in an instance where you want to be able to snug the fitting enough to securely orient something like a ball valve, the standard nipple is a much better choice.

Problem solved! October 18, 2018
Reviewer: Amando Cardenas from ESCONDIDO, CA United States  
This is Bobby's "shtick" offering product that solves problems. Just like he suggest, run a lil extra Teflon or use the thicker stuff & it will not leak!
