This fitting is a BrewHardware.com exclusive. One side is a standard 3/8" tube compression fitting and the other has a nice flanged surface to either weld or silver solder into your tanks, pots, lids, fermenters, etc.
Note that the fitting is bore through, meaning the 3/8" tubing will pass all the way through the fitting.
You'll need to drill a 1/2" hole in the pot or surface.
We also stock this fitting in 1/4 and 1/2" tube compression sizes.
OPTIONS:
Besides the tube size option, we also offer a choice between stainless and nylon compression rings/sleeves.
Stainless Ferrule: This is a set of rings/sleeves/ferrules that slip over the tubing, but behind the compression nut that get squeezed onto the tubing when you lock the nut down TIGHT for the first time. This process permanently crimps the rings to the tubing though you can still remove the compression nut and tubing (though the nut is now captured). This option is more difficult to use and requires a lot of torque to set, however it is the better mechanical option where a lot of stress is put on the connection.
Nylon (AKA Delrin) Sleeve RECOMMENDED!!!!: This option replaces the pair of stainless rings with a one-piece wedge ferrule made of a tough, high temp, food grade plastic. It seals well with minimal tightening on the nut (hand tight plus a quarter turn), never attaches itself to the tubing permanently. Although it is plastic, it does allow for many disconnection cycles without wearing out. The only down side is that it doesn't offer the same mechanical strength as the SS version in cases where a LOT of stress is put on the connection.
