SHIYO OXYGEN / ACETYLENE HOSE CHECK VALVE

Features :
 

These are not flashback arrestors and should not be used as a standalone defense against flashbacks.

They are check valves that should be used in combination with flashback arrestors. They are only part of a flashback prevention system. Check valves are a first line of defense against flashbacks.

Installed at the torch, they are meant to protect your hoses and provide some protection against flashbacks. Flashback arrestors must also be installed at the regulators in combination with these check valves.
