Harden seat and Barrel for single handle tub shower valves.
Finally! It’s been driving us crazy having to tell customers that no parts were available for their Harden tub/shower Single lever control valve. So, we convinced an aftermarket manufacturer to start making them! Theses are the seat and barrel for cartridge #86-5111 which is 6” long, and can be shortened. It is recommended to swap out seat, barrel, and cartridge when servicing these valves.
