REGO A7537N4 Excess Flow Half Coupling 2” MNPT In x 2” M & 1-1/4” F Out

REGO A7537N4 Excess Flow Half Coupling – 2” MNPT In x 2” M & 1-1/4” F OutThe REGO A7537N4 Excess Flow Half Coupling is an OEM safety component designed for threaded container installations in propane systems. This excess flow device provides automatic shut-off in the event of a downstream line failure while maintaining exceptionally low pressure drop, making it ideal for pump suction lines and high-flow applications.This half coupling may be used for filling, liquid withdrawal, or vapor equalizing applications. When installed with a riser pipe to the vapor space, the riser pipe inside diameter must be at least two times the valve thread size to avoid flow restriction to the side inlet ports.Key Benefits:Genuine REGO OEM excess flow coupling2” MNPT inlet2” Male & 1-1/4” Female NPT outletsAutomatic excess flow shut-off for safetyLow pressure drop designIdeal for container and bulk tank installationsTypical Applications:Propane container installationsBulk tank filling and withdrawal linesPump suction pipingVapor equalization systemsREGO excess flow devices are trusted throughout the propane industry for safety, reliability, and long-term performance.
