In the response from"DeltaFaucet2" posted 5 years ago, Marc, Thank you for your question. I have attached the breakdown of the cache aerator to the smallest level that we have. Thanks, Dave --> what is the item number for the part #1 in diagram?

Asked by: needapart
Thank you for your question, ! Although we were able to provide a closer breakdown of this aerator, unfortunately RP54977 does not have individual parts available for order and a new aerator will need to be purchased. Best regards, Edward

Size of aerator o-ring

The o-ring on my Aerator broke when I removed it to clean. What size of o-ring do I need to get to replace it without replacing the entire aerator.
Asked by: Mark
Hi Mark, Thank you for your question. The gasket for your aerator measures .591" ID x .693" OD x .10" thickness. Best regards, Jon

do you make a aerator that is 2.0 gpm

Delta 3538-MPU-DST need a 2 gpm aerator for my tankless water heater to operate.
Asked by: Tom
Hi Tom, Thank you for your question! We do not manufacture a 2.0 gpm aerator for the 3538-MPU-DST. However, I can provide the thread size of the aerator the faucet uses which is 13/16"-27 male. Best regards, Brandis

Need aerator wrench for delta lahara wide spread 2 handle faucet

The part number listed on parts diagram list part number rp54977. Which indicate the wrench and aerator together. I bought rp52216, it works on my single handle faucets, but is too large for the 2 handle faucet. I need the wrench for the 2 handle faucet, as well as replacement aerators. The house was built in 2010, and the plumbers did not leave any of the wrenches.
Asked by: Andy
Thank you for your question. Delta Faucet model # RP54977 will use wrench model # RP60730 which can be purchased from your local wholesaler or retailer.
