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

Exactly what I needed.

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.

Is very useful , is the exactly solution

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 drainsNeed to install these ABOVE the p-trap, and helps if your sink has PVC (not metal) tail drain.

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!

Looks awesome but did not silence my drain noise or make it quieter at all. *UPDATE* after messing with the position of the coupler I was able to silence my drain by about 90 percent. Huge improvement from a drain saddle (which goes against codes)
