SKU 43421_RJIRO
This shower cartridge acts as a repair kit for single handle 13/14 series bathtub and shower faucets, compatible with select rough-in models. It features pressure balance technology to keep water temperature within a safe ±2°C range, shielding users from sudden shifts in hot or cold water pressure that could cause uncomfortable or unsafe conditions. Crafted from durable plastic, it extends the product’s service life while helping conserve water and cut down on long-term repair costs. Installation is straightforward, needing only basic tools and no wall demolition; users simply need to clear away contaminants from the area around the old cartridge before fitting the new part. Before purchasing, confirm your faucet’s model and manufacturing year—units made before 2016 are blue, while those from 2016 onward are off-white, and this part is not compatible with 1300/1400 series or dual-handle fixtures.
