10” BUBBLER/SCRUBBER 12" tall slim Filter clear/purple acrylic filter housing. 4-3/8" wide white plastic cap with 'o' ring. Comes with SS bracket & 4 ss tap screws. Can also be used as a 10" Hydroxy Dryer as well. You decide below, in drop down menu. Choose either a dryer/filter or the PEX bubbler tube. The IN becomes the OUTlet when used as a bubbler. You choose a 11" piece of .5" Aqua-PEX tubing or a poly spun 10" filter, in the drop down menu below. The Aqua-PEX tube fits snug without gluing in. Has 1/4" NPT ports on both the IN and OUT. Drill a few 1/8" holes in the tube near the bottome and your good to bubble. Scrubbing meaning it takes the electrolyte off the hydroxy gas and leaves it in the water. Also works as a safety flash back arrestor, as a flash back (spark) cannot travel though the bubbler to your cell. Drill any size holes into the tube. We use a 1/8" drill bit. Another view of the bubbler in action. 10" is the filter size that fits inside 2" x 9.75" filters. We reverse the OUT to be the IN, when we have this housing a bubbler, as the out takes the center tube down to the bottom of the container. The IN is now the out gas. These acrylic ( lye proof) bubblers NEVER have a leak issue, as the poly water tank lids can have.
