## Overview

The Blue Viega ManaBloc Stems (3-pack) are authentic OEM components made in the USA, crafted from durable diamond material with NPT threading. Designed to reduce flow noise, these compact stems measure 6 x 1.5 x 1 inches and come in a convenient triple pack, perfect for professional-grade plumbing installations.

## 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.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Original Quality and Fit
*by C***C on June 22, 2025*

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.

### ⭐⭐⭐⭐⭐ Worked great, easy to replace.
*by A***R on March 31, 2025*

Worked great on my mana block system manufactured in 1999/2000 to replace broken stems that I could not turn off.

### ⭐⭐⭐⭐⭐ Perfect fit
*by A***R on November 21, 2024*

I recently installed the Blue Viega ManaBloc Stems in my plumbing system, and I couldn’t be more pleased with the results. The installation process was a breeze. Each stem fit perfectly into the manifold, allowing for a seamless connection that felt secure and reliable.Overall, I highly recommend Blue Viega ManaBloc Stems to anyone looking to upgrade their plumbing system. They are a perfect fit for the manifold, easy to install, and built to last. This product truly exemplifies quality craftsmanship and functionality.
