Delta Faucet RP51503 Bonnet Nut

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

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!

One of the parts needed to repair leak in kitchen faucet. Exact replacement part.

When I replaced the control valve I replaced the bonnet nut. Logical thing to do. The bonnet nut was an exact fit.

Worked

Well made replacement part. Old bonnet nut was stuck because the previous one was installed without any grease. Carefully cut old one off with a dremel tool without cutting into faucet base. Pried apart with large screw driver and removed. No more leaking faucet.

Replaced the valve cartridge today with the new one. The steps to do it are simple but the actual removal of the old parts took more time because apparently our water left deposits on the bonnet cap and brass bonnet nut that made it more difficult to remove them. Had to gently use adjustable pliers, which I really didn't want to do. Luckily I had decided to also order the new bonnet nut too. The new parts fit and look just like the originals and the faucet works like new with no drips.

it fit

This is an original product that works as you should. No manufacturing defects or anything, its just as it should be. Watch your wet hands on the sharp new threads. I got sliced up a bit, but that's just any new threaded fitting.
