    Solved our leaking problem!

I just changed the cartridge recently but our kitchen faucet was still leaking. Then I bought this and it solved our problem!

    Perfect replacement for original Bonnet Nut.
  

*by L***N on Reviewed in the United States on March 8, 2023*

I had to replace a leaky diamond seal cartridge on my delta faucet and noticed that the bonnet nut looked like it also needed replacing.  Purchased this and it worked perfect.  One word of advice, when screwing the bonnet on, push down on the rubber part so it fits inside the faucet housing.  I didn't do this at first and the rubber part was sticking up so far, the bonnet wouldn't line up with the threads.  Pushing down on the rubber part helped push it down to where it needed to be and then the bonnet screwed on easily.  Faucet works perfectly now with no leaks!
