Product Questions

Would I be able to use this with the DOS air line tubing?
Question by: Alvin Alejandro on May 23, 2016 6:27:00 PM
Great question! Unfortunately the DOS tubing will not be an exact fit.

What size drill bit do you need to install these?
Question by: Ryan Rhatican on Apr 14, 2016 8:53:00 AM
Great question!
These will need a hole size of 3/4" for installation. Feel free to let us know if you have any further questions!

Do you think this would this work to convert a bottle (e.g., of NO3:PO4-X) to a dosing container, by drilling the lid to accommodate this bulkhead, and attaching a 1/4" Clear Acrylic Tube (your SKU: 207841) of the appropriate length to dangle inside the bottle (also assuming the lid is drilled to allow air in)?

Get this be used for a wet application if I use a gasket?
Question by: 402jasonn on Nov 8, 2013 2:20:00 PM
Good question. Unfortunately it cannot be as water would still travel through different parts of the fitting. Its meant for non-submerged applications like running a tube through a cabinet, etc.

  • Good as long as you take the time to make sure it's setup properly. By Chris on 6/23/2016

    I bought two of these for my dosing pumps and containers with the intention of using them with the 1/4" rigid acrylic tube into the top of my dosing container. when I first hooked these up they both leaked pretty bad and wouldn't reliably dose my 2-part. For one the acrylic tubing is extremely tight and difficult to insert and remove. I ended up fixing the leaks by making sure my end on the acrylic was exactly flat and I used a small piece of sandpaper to make sure it was absolutely flat and smooth. I then removed the collar on the side opposite of where I put the acrylic and then inserted the acrylic tubing making sure it was completely seated and I couldn't see any of the two O-rings from the top. Similarly I used the tubing cutter available on BRS to make sure the tubing was completely straight. Overall this is a great product for a clean install as long as you are very careful when attaching the tubing especially the rigid acrylic. BTW I had better luck with the clear tubing in the dosing pump rather than the translucent ro tubing.
  • a must have By chris on 4/27/2016

    Bought 2 for 2 part dosing system, 1 is leaking, trying to figure a way to seal it without ordering another, don't want to wait for shipping.
  • Just right By Saltchip on 4/15/2016

    They work perfectly. 3/4" step bit hole is just right. Will buy more. I am getting the elbows to go with them.
  • Awesome By Randy on 4/13/2016

    These worked amazing when I converted the OXO Flip Lock Containers to hold everything I dose.
  • Perfect By Ken on 9/16/2015

    It's solid and well built. It keeps an airtight seal, not only at the screw-tight bulkhead, but between the two 1/4" lines. I'm using it on my ATO reservoir and it works perfectly. The pump does not suck any air up with the water and is able to hold that vacuum when the pump stops. Perfectly airtight. I'm ordering more for my Cal and Alk 2-part jugs.
  • Works Great By Terri on 5/16/2015

    I have 3 for the alk dosing containers. Bought 3 more and the acrylic tubes so the alk and ca containers are all taken car of! No more worries about the tubing curling up and not getting the solution drawn up and into the sumps. Definitely a must have:0)
  • Awesome By Mack1969 on 4/6/2015

    This is my 3rd bulk head I broyght for my containers! It makes it easy to disconnect and connect! A must have for dosing!
  • Great product By Phil on 2/4/2015

    Fits perfectly in the opening of an Oberweis milk bottle. Great for DIY dosing systems.
  • Great product By Phil on 2/4/2015

    I bought these to used with my diy dosing containers. When I got them I ended up using oberweis milk bottles instead because this bulkhead fit perfectly in the opening. I works Well with airing tubing as well.
  • 1/4 push connect bulk head, as advertised By charles on 1/6/2015

    You don't need the rigid air line to use this. I used 1/4" OD Vinyl ice machine water line from local hardware store. $1.98 for 10 foot .Cut to length to put the soft line in to a corner and cut to fit. The top side i connected tot he BRS 1.1 mill/min dosser pumps.
  • Great product By Chad on 11/2/2014

    I used this as the connector into my RODI barrel and it works perfectly for that. no leaks so far and allows the other connectors to work perfectly.
  • Great for dosing. By Steven on 5/14/2014

    This is great to add to any jug or container you are going to dose with. Gives your container a professional look, no longer need the tacky hose just shoved into the opening and hanging there. Also allows you to refill set container without disconnecting.
