Drain Line Adapter (DLA) with 1/4-inch Quick Connect Fitting for Reverse Osmosis filter (ET112-001, 12-25QC, DLA-12)

Easy to install, leak free. I’m using it horizontally on the non garbage disposal side of double basin sink.

Awesome design, Much more secure than the sale style. really liked how easy it was to install. In my situation I was literally able to just cut across where I drilled the hole for the saddle style to install and put one piece on either side and that was pretty much it. But that's been my case in another situation it may no work. Verify if it'll work for you. Price in my opinion is a bit steep but it worked so can't complain about that. It fit my application at 1-1/2" pipe just right. Too maybe 5 minutes to install. The was used on my aqua true system.

Fit great and does not leak, fixed my ro problem

While a bit on pricy side, these are a REAL RO drain solution. I wish iSpring and other RO MFGs would include these with their systems, instead of the leak prone saddle valve type drains Need to install these ABOVE the p-trap, and helps if your sink has PVC (not metal) tail drain.

When I was looking to install my undersink reverse osmosis system, I noticed that many people mentioned the saddle connector supplied by the mfg for connecting the drain line wasn't always acceptable to code, and it meant drilling a hole in my current drain pipe. This seemed a lot simpler and more robust. I haven't had any problems with it. I'm happy I went with this. I'd buy it again if I needed to do something similar.

While trying to replace our current RO system with the new system/collar for the drain line, we realized that in order to use the collar we would have to replace all the plumbing under the sink. Luckily, Amazon carried the 1/4" drain line adapter and the seller had the part here the next afternoon. The DLA hooked right up , drain line went in, and even had the notch on the adapter for the blue clips to secure the tube. We have had it up and running for about a day and no leaks from installation. I would highly recommend this product as it is easy to install. We actually split a pipe trying to drill a hole for the collar version. This product made installation easy and hassle free.

All the above. All was good. I would buy it again n again.

I received the package and the 1/4” locking clip was not even included! I’m very disappointed with the seller! I had to contact Amazon customer service and Amazon refunded the full amount. I am very happy with Amazon’s customer service, but not happy at all with the seller sending me the product without the locking clip! If I could, I would give Airgap International ZERO STARS! I had to buy a separate locking clip off of Amazon from another seller, which set me back from being able to install the adapter even further! Buyers Beware! You might pay for the adapter from Airgap International and not receive what you paid for!
