## Overview

The K-Musculo Oxy Hydrogen Flashback Arrestor is a commercial-grade safety device engineered to prevent dangerous flashbacks in hydrogen-oxygen systems. Featuring a high flow rate of 116 liters per minute, an internal check valve, and a porous metal shield housed in durable brass, it supports pressures up to 140 PSI and fits 1/4" ID hoses. Designed for professionals demanding uncompromising safety and performance in industrial environments.

## 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.
