## Overview

The Blue Viega ManaBloc Stems (3-pack) are original OEM replacement parts made in the USA, designed to fit older Manabloc systems. Featuring a redesigned larger diamond pin for enhanced durability and reduced flow noise, these stems ensure reliable ¼ turn on/off operation with full 360° rotation compatibility. Ideal for professionals and homeowners seeking a precise, long-lasting plumbing repair solution.

## Description

Replacement stems for older Manabloc systems that originally had black stems. The older black stems with a smaller diamond pin are no longer manufactured. There was trouble with the black diamond pin breaking off so they redesigned the stem, changing them to red or blue color and increasing the size of the diamond pin to resist breaking. If your existing ManaBloc stems are black, red, or blue and turn 360 degrees this is the correct product for your system. Stem turns ¼ turn to off or on, but will turn 360 degrees around. This newer stem uses the red T-handle (50601) which has a larger diamond slot.

Review: Original Quality and Fit - The work and fit as they should. I don't particularly like Manabloc but the house came with it. If you got hard water, buy extras cause even with a water softener, every time you turn these things they leak. Its like if you turn it, replace it. Put a bit extra silicone grease when you install them to "help" with future service.
Review: Worked great, easy to replace. - Worked great on my mana block system manufactured in 1999/2000 to replace broken stems that I could not turn off.
