Product Questions

I use the standard 1/4" PUSH CONNECT BULKHEAD TANK ADAPTER for current dosing set up, so I can have lids on my dosing containers. I realize the DOS line is larger in diameter than that. Is there a replacement bulkhead that BRS sells so I can either swap out my bulkheads or convert the DOS line to the 1/4" rigid air line / clear acrylic tubing?

Great question!
Unfortunately the Bulkhead tank adapter will require firm Polyethylene tubing which the DOS tubing will not work with. You may be able to try 1/4" RO tubing to attach the to DOS however this will not be a guaranteed fit.
