Mezvion 1222 Cartridge Kit for Moen Posi-Temp – Includes 104421 Puller & 116653 Adapter

Mezvion 1222 Cartridge Kit for Moen Posi-Temp

Upgrade your single-handle Moen Posi-Temp tub and shower with the Mezvion 1222 cartridge kit. This thoughtfully engineered package combines rugged materials with a design that supports precise control and easier service in busy bathrooms. The centerpiece is an upgraded stainless steel sleeve that replaces common plastic components, delivering superior rigidity and resistance to corrosion and lime buildup in humid spaces. The result is a firmer handle feel and reduced wobble, making daily showers feel more predictable and comfortable.

Inside the cartridge, a brass core works with premium rubber seals to create a reliable seal and stable water flow. The integrated pressure-balancing mechanism helps maintain a consistent temperature as supply conditions change, providing a smoother shower experience without dramatic temperature swings. This direct-fit replacement respects the original Moen 1222 system, helping restore smooth operation and dependable performance without replacing the entire valve.

Direct compatibility and complete repair kit

This kit is designed as a direct replacement for the Moen 1222 cartridge, ideal for Moen Posi-Temp single-handle fixtures where the cartridge is worn or leaking. It includes everything you need for a full repair: the 1222 replacement cartridge, the 104421 cartridge puller for safe removal, the 116653 metal adapter for handle compatibility, a temperature limit stop, a retainer clip, and lubricating grease for a smooth installation. The puller is specifically designed to help you execute a quick, low-risk replacement without risking damage to the plumbing.
