## Overview

The K-Musculo Oxy Hydrogen Flashback Arrestor is a commercial-grade safety device designed to prevent dangerous flashbacks in hydrogen-oxygen systems. Featuring a high flow rate of 116 liters per minute and an internal check valve combined with a porous metal shield, it ensures maximum protection. Constructed with durable brass housing and rated for pressures up to 140 PSI, it fits standard 1/4" ID hoses, making it the trusted choice for professionals demanding reliable, high-volume safety.

## 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.
