FOXX Counter Pressure Filler Description Here is a general description of how a Foxx style Counter Pressure Filler is made for those of you who do not have the ability to observe one. The filler is generally T shaped with the bottom of the T dipping down into the bottle and the horizontal top of the T attaching to inputs. The horizontal part of the T consists of two valves on either side of a brass 1/4" NPT T, comprising gas and liquid in. In the bottom of the top T, is a 1/4" MNPT x 1/4" compression fitting. Into the compression fitting is a length of 1/4" OD SS rigid tubing, about 12" long (YMMV depending on bottles used, cut it longer and later have to trim, rather than being too short). Now construct the bottle adapter part. Take a 1/4" brass T and turn it on its side with the former bottom pointing to your right. Into what is now the top, insert a 1/4" MNPT x 1/4" compression fitting. Into what is now the bottom, insert a 1/4" MNPT x 3/8" compression fitting. Get a 2" piece of 3/8" copper tubing and insert it into the compression fitting and tighten down. In the right side of the T (formerly the bottom) insert a 1/4" MNPT x 1/4" compression right angle needle valve. Into the 1/4" compression, insert a 2" length of copper tubing and secure. While still holding the bottom assembly with needle valve on the right, pick up the top assembly and slide the SS tubing down through the 1/4" compression fitting in the bottom assembly, and slide the bottom assembly all the way up to rest against the compression fitting of the top assembly. With the whole thing laying on a flat surface, tighten the last compression fitting, keeping the assembly planar. Take a rubber stopper the right size for a bottle and with a 3/8" hole in the center and slip it up over the SS tube and then over the copper tubing. The wide part should be towards the top of the filler. Attach a "waste" hose of clear vinyl tubing to the copper stub coming out of the needle valve.
