Understanding the QCC1 Connector
Understanding the QCC-1 Connector
The QCC-1 connector is a modern, user-friendly connection system for propane cylinders. Often called the "new style" connector,
it replaces older POL connections with improved safety and convenience.
Design and Compatibility
The QCC-1 uses a nut-and-nipple assembly and is easily recognized by the large, external right-hand threads on the cylinder valve.
Its patented nut is designed for tool-free connection—simply hand-tighten to secure. For added versatility, the nut also features
internal left-hand threads, allowing compatibility with appliances that still use traditional POL connections. Additionally, this design
enables LP suppliers to refill cylinders without needing a separate adapter.
Safety Advantages
The QCC-1 system offers several safety features not found on most POL connections:
Flow Limiting Device: Located in the nipple, this patented mechanism shuts off gas flow if a leak occurs between the regulator and the appliance burner valve.
The device resets each time the cylinder valve is opened—but only if the appliance is turned off. If the appliance is left on when the valve is opened,
the device will restrict gas flow and fail to reset.
Heat-Sensitive Shutoff: The connector is designed to automatically stop gas flow if exposed to temperatures between 240°F and 300°F,
providing an added layer of protection in fire-related scenarios.
for modern propane systems.
Understanding the POL Connector
The POL (Prest-O-Lite) connector is a traditional brass nut-and-nipple fitting commonly used for propane cylinders.
It features left-hand threads and requires a wrench for proper tightening.
Often referred to as the "old style" connection, the POL remains widely recognized in the propane industry.
