8 Pieces Rp25513 Faucet Stem Assembly Replacement Repair Kit for Two Handle Faucet Cartridge Replacement Parts with Rp4993 Rubber Seat and Spring for Kitchen Bathroom Outdoor Faucet

Easy to replace, plastic blocks must be in correct location for hot and cold. Work perfectly, only thing I’ve noticed is a reduction in water compared to the originals.

The kit include seats and springs and it is very good quality. Will buy it again.

I ordered this 8-pack because I had several faucets that were dripping and I wanted to replace the cartridges in both hot and cold at the same time, They went in fine, fit okay but the water pressure is now much lower than before, The faucets work but definitely not like before. I would not purchase these again

Muy bien

These are an excellent replacement for the OEM Delta cartridges. They are almost 70% less in cost, based on the quantity you purchase.Several reviews indicate that water flow is diminished with these cartridges. As you can see in the photo, the flow control plate on the bottom of the right replacement cartridge, has a smaller opening for water flow. (Cartridge on left is the original Delta cartridge, and cartridge on the right is the after-market cartridge purchased on Amazon)In order to circumvent the loss in water flow, remove the flow control plate from the original Delta cartridge. Use a 2mm screwdriver to gently lift the tabbed edge from the side of the cartridge as in the next photo. No need to bend it fully outward, but barely enough to just release it from the original cartridge.Do NOT use the screwdriver on the bottom of either cartridge as shown in the 3rd photo. This will damage the bottom of the cartridge, as the plastic is rather soft.Next. remove the flow control plate from your new cartridge and replace it with the original Delta plate. Make sure you’re putting it on in the correct position. Once replaced, use the tip of the screwdriver to gently press the tabbed edges securely into place.When it comes to fixing plumbing issues, I specialize in making everything leak worse than when I started. (I’m horrible at fixing plumbing!) But in the case of these cartridges, I left the faucet handle covers off for a few days to see if they might leak. But they never leaked. So I would def recommend these cartridges.

It fits delta faucets and doesn’t leak. Serves well for the purpose!

Fit was good. Had to replace 2 of them. Wouldn’t seal

I fixed all my delta faucets around the house. The handles operate so smooth now! No leaks anywhere! Good quality, get them... you won't be disappointed!
