Helhom Shower Faucet Cartridge Assembly, Single Handle Tub and Shower Replacement Parts, Equipped with Bonnet Nut

This precision replacement part is tailored for single-handle tub and shower valves from the 1300 and 1400 series, compatible exclusively with pre-2007 models and not suitable for post-2007 universal valves. It delivers reliable pressure-balanced performance that keeps water temperature within a narrow range, stopping unexpected hot or cold shifts that can disrupt or endanger showers. Built with a sturdy brass core and reinforced plastic components, it ensures long-term use without leaks while capping maximum hot water flow to mitigate scalding risks. An integrated hot water limiter further enhances safety by blocking excessive water heating. Installation is straightforward and tool-free, as the part drops directly into place without needing to fully remove the existing valve, though users should clean the old valve seat prior to setup for optimal fit.

• Built-in hot water limiter prevents overheating
• Brass core and reinforced plastic ensure leakproof operation
• Drop-In Replacement design for tool-free setup
