## Overview

The K-Musculo Oxy Hydrogen Flashback Arrestor is a commercial-grade safety device engineered to prevent flashbacks in hydrogen-oxygen systems. Featuring a high flow rate of 116 liters per minute, an internal check valve, and robust brass housing, it ensures maximum protection and durability.

## Description

The biggest safety concern when using hydrogen flashback arrestors is the chance of exceeding the volume rating of the arrestor. Many flashback arrestors are only rated at 10 liters per minute. If you exceed that volume, and a flashback occurs, these low volume arrestors may not stop the flashback. This is why we sell only high volume commercial quality flashback arrestors, with the added protection of an internal check valve. For your safety, it is best not to take a chance on low volume arrestors. Only high volume arrestors will offer you the safety that you need to be assured you and your system are protected.
