Marshall Excelsior Type 1 QQC Connector ME518

Marshall Type 1 Qqc Connector ME518

The Marshall Excelsior ME518 Type 1 Qqc Connector is an essential component for safe and efficient propane gas usage. It features a 5/16" Female Acme Inlet with a 100 SCFH Air/200,000 BTUH Flow Capacity, providing reliable and high-performance gas flow.

Key features include:

• Built-in Excess Flow Feature: The connector is designed with a built-in excess flow feature, ensuring that gas will not flow until the connector is fully engaged, enhancing safety and preventing gas leaks.
• Positive Shutoff: This connector incorporates a positive shutoff mechanism that prevents gas from flowing until fully engaged, adding an extra layer of safety and control.
• Thermal Protection: In the event of a fire, the built-in thermal protection melts, allowing the nipple to disengage from the tank connection and stop the flow of propane, providing crucial safety measures.
• Positive Back Check Seal: The QCC connector provides a positive back check seal at disconnect, preventing the release of propane into the atmosphere, promoting environmental responsibility.
• Thread Replacement: The Type 1 (QCC) thread replaces the POL connection on 40 pound or less DOT propane cylinders, offering versatility and compatibility.

Important Note: An excess flow valve will not activate if there is a break or leak downstream of the valve that does not equal or exceed the closing flow of the valve or if the excess flow valve installed exceeds the flow capacity of the system.

Warning: It's crucial to ensure proper installation and understanding of the system to maximize safety and efficiency.
