Check valves provide protection against reverse flow of gases, but not flame flashback. Uniweld’s check valves conform to OSHA safety standards, (*UL Listed). They’re easy to install, test and service. Color coded, Green: Oxygen and Red: Fuel Gas.

Flashback arrestors installed at the torch help protect the technician and at the regulator, help protect the equipment.
