Product Benefits Restore smoother control to a worn or dripping mixer tap with this QZKJQDD tap cartridge replacement set. The pack contains separate hot and cold valves, identified by red and blue rings to help reduce installation mistakes. Each valve uses a quarter-turn ceramic disc mechanism for convenient 90-degree operation. The brass body, reinforced thread and sealing O-ring provide a stable fit when matched with a compatible tap. Suitable for repairing compatible bathroom basin taps, kitchen sink taps, vanity taps and utility sink mixers. Replacing the internal valve can provide a practical alternative to changing the complete tap assembly.

This product is a complete valve cartridge kit rather than a packet of loose tap washers. It will not fit every mixer tap model. Always shut off the water supply before removal or installation.
