T & T Replacement Cartridge Compatible With Delta Peerless RP70538 – Single-Function Mixing Valve, 3-1/8″ Height, 40mm Width, Brass Broach

About This Product

This replacement cartridge from T & T is a solid drop-in alternative for the Delta/Peerless RP70538 valve, and it also fits a bunch of other brands including Glacier Bay, Pegasus, Aquasource, Baypointe, and Homepointe.

It's a single-function mixing cartridge that balances hot and cold water pressure so your shower temperature stays steady—no sudden scalding or freezing when someone flushes a toilet.

Dimensions are 3-1/8 inches in height and 40mm wide, so it matches the original specs.

The brass broach design is compatible with Delta, Peerless, and Glacier Bay handles, and the threaded insert works with handle screws.

Installation is pretty DIY-friendly: shut off water, remove the handle, pull the old cartridge, grease and insert this one, then reassemble.

It's a much cheaper fix than replacing the whole valve body.

Made by Byson International in Taiwan, so you're getting a quality aftermarket part that's been tested to hold up.

Great for homeowners or plumbers who want an affordable, reliable repair solution.
