This complete replacement cartridge kit is designed for common single-handle shower faucet maintenance, delivering all necessary parts to resolve issues like dripping, unstable water temperature and abnormal water output. The main cartridge is built with a solid brass core, which effectively reduces the risk of leakage by half compared to old plastic core alternatives, extending the service life of the repaired faucet. The included dedicated cartridge puller lets users take out the worn old cartridge without scratching or damaging the connected plumbing pipes, no extra destructive disassembly is needed. The supporting lubricating grease, metal adapter, temperature limit stop and retainer clip ensure every worn component can be swapped out to bring the faucet back to brand new working condition. The built-in pressure balance structure automatically adjusts water pressure to avoid sudden scalding or cold shocks when other water fixtures are turned on elsewhere in the space, creating a safe and comfortable shower experience for all users. It works for most posi-temp single-handle shower faucets, suitable for both residential home renovation and commercial public restroom repair projects. Color: Silver.
