Assembly and Fitting Instructions
Designed to be fitted to oxygen and acet/fuel gas regulator outlets. Each con-
tains a sintered steel flame barrier and a spring-loaded reverse flow check valve.
In the event of a flashback, the barrier will stop the flame from reaching the
check valve and regulator. The check valve will prevent one gas from flowing
into the other regulator. A check valve alone will not stop a flashback.
