37-Pack Cup Seal & Diverter Gate – Compatible With Moen 3800 Tub Spout Replacement Parts

About This Product

If your Moen 3800 tub spout is leaking or the diverter isn't switching smoothly, this replacement kit is exactly what you need.
You get six rubber cup seals and six plastic diverter gates – enough to do multiple repairs or keep spares on hand.

The cup seal diameter is 2.

54cm (about 1 inch), and the plastic gate is 3.
05cm long.
They're made from good quality rubber and hard plastic, so they hold up to daily use and hot water without deteriorating quickly.

Installation is DIY-friendly: use a small screwdriver to separate the locking lugs on the lifting bar, remove the old diverter gate assembly, slide the new gate with the rubber gasket into the spout, and put the lifting bar back.

That's it.
No special tools or plumber needed.

These parts effectively prevent leaks and restore smooth water flow, helping you switch between tub and shower effortlessly.
Perfect for homeowners who want a quick fix without replacing the whole spout.
