Rated 4 out of 5 by from Coordinated with New Faucet I had chrome and replaced with this to match new faucet. Not a perfect match but very close. I had to replace the previous base with the one Delta provided. A very simple task, taking less than 10mins.

Rated 1 out of 5 by from water all over counter I bought the air gap and cover to replace one that the builder had literally left under the sink. I have run the dishwasher 2x's and each time, water bubbles out of the air gap onto my counters.... The plumbers were out today to make sure that no lines were clogged: they weren't. They disconnected and reconnected the lines: tested it again....water all over the counters. There is a flaw in the design of the plastic air gap...have to go to a plumbing store to get a new plastic air gap... (The cover is far.)

Rated 1 out of 5 by from Amazon sends unbranded boxes The only place I could find to buy the "SS" color to match the faucet finish we want was amazon. Ordered 2 (we're getting 2 dishwashers!), and received two boxes from them, neither identifies as being a "Delta" product as the description indicated. Not sure where else to find them as none of the authorized dealers carry this finish. Can't order them from here because Delta doesn't personally sell their own products. Disappointed my faucet I was so excited to get back (I had a Touch2O at my last house that I sold) might have to go back for a brand that offers matching code required accessories :(

Rated 5 out of 5 by from Quality Air Gap This is a quality air gap from Delta. It's much better than the cheap ones you'd buy at the home improvement stores. The Delta air gap has thicker metal and better looking chrome than the others. The trick to installing this is to set the plastic mounting assembly at the correct height- if it's set too high then the chrome cap won't cover it entirely. When you've got it set just right the chrome cap comes all the way down to sit right on the sink surface.

Rated 5 out of 5 by from Matches the faucet perfectly We replaced the satin finish faucet in the kitchen and this was the only website I could find a Venetian Bronze Air Gap. Delivered quickly and fits perfectly.

I want to buy a replacement cap only for my kitchen air gap (part #72020-SS.)  What is the part # for the cap only? Also, my new faucet is a Delta in Arctic Stainless but my sink is older and brushed stainless.  Would you suggest SS or AR for the cap?

Asked by: C1DonnaC
Thank you for your question, C1DonnaC! This Delta Air gap does not break down into individual repair or replacement parts and the cap is not available separately. Best regards, Edward

I am trying to match Kitchen Air Gap to the Owendale 19875Z-SPSD-DST, which is the recommended match, Artic Stainless or Stainless on the 72020?

Asked by: Jeannine
Hi Jeannine, Thank you for your question. The Delta Air Gap 72020-SS model would be the closest matching finish to the Delta Owendale Kitchen Pull-Down 19875Z-SPSD-DST faucet. Best regards, Tanya

I am looking at 599-SSMPU-DST versus the 699-SS-DST faucets for undermount sinks in the bathroom. Do you recommend one over the other in this application?

Asked by: Kaybob
Thank you for your question, Kaybob! The model 699-SS-DST has a taller spout and is designed for vessel sinks. It also does not include a pop-up drain assembly. If you do not have a vessel sink, the 599-SSMPU-DST would be recommended but it depends on your personal preference as either could be used. Best regards, Jon
