The \u003cstrong\u003eMiller Smith H753 Combination Flashback Arrestors\/Check Valves\u003c\/strong\u003e are regulator-mounted safety devices sold as a pair, designed for oxy-fuel cutting and welding systems. These units combine two critical functions in a single device: extinguishing flashback fires and stopping reverse gas flow. Mount them between the regulator and the hose for protection at the source.\u003c\/p\u003e\u003cp\u003eFlashback arrestors are an essential safety component in any oxy-fuel setup. A flashback occurs when mixed gases ignite within the system, potentially sending a flame back toward the gas supply. The H753 units extinguish that flame before it can travel further. The integrated check valve adds a second layer of protection by shutting off gas flow when back pressure drops below ½ psi and requires a minimum of 2 psi to open and allow gas to flow through.\u003c\/p\u003e\u003cp\u003eUnderstanding the difference between a check valve and a flashback arrestor is important: a check valve stops reverse gas flow, while a flashback arrestor extinguishes a flashback fire. The H753 does both. Mixed gas explosions and flashback fires can result in equipment damage, severe personal injury, or death, which makes these combination units a critical part of any safe oxy-fuel workstation.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eCombines flashback arrestor and check valve in a single unit\u003c\/li\u003e\n\u003cli\u003eRegulator-mounted design installs between the regulator and the hose\u003c\/li\u003e\n\u003cli\u003eExtinguishes flashback fires caused by ignition of mixed gases in oxy-fuel systems\u003c\/li\u003e\n\u003cli\u003eIntegrated check valve shuts off gas flow when back pressure drops below ½ psi\u003c\/li\u003e\n\u003cli\u003eMinimum of 2 psi required to open the check valve and allow gas flow\u003c\/li\u003e\n\u003cli\u003e9\/16\" connections (18 STD.
