Rexarc liquid flashback arresters are designed to operate in medium pressure fuel gas piping systems. Arresters protect the main gas supply from dangers of reverse flow and flashbacks.

To service your Rexarc liquid flashback arrester, or to check its liquid level, close the shut-off valves on both the inlet and outlet. Relieve pressure by operating the pressure relief valve. Installation should comply with National Fire Protection Association Booklet #51 and local codes.

Pressure relief valves are required in fuel gas systems to prevent excessive pressure build-up within the system. Rexarc fuel gas relief valves will vent automatically at preset pressures or may be manually operated to relieve pressure within the system. Pressure relief valves are required in oxygen, inert gas systems to prevent excessive build-up within the system. The Rexarc oxygen, inert gas relief valve will vent automatically at preset pressure.
