Type 1 / QCC1 and POL propane tank connectors compared

QCC1 typically tightens over the outside of a modern cylinder valve. POL uses the internal valve thread and a left-hand fuel-gas thread. Neither tank end establishes the appliance-side requirements.

This page coversIdentification comparison only. Confirm the tank valve, regulator, pressure, and appliance end from current documentation.

A picture can help identify the connector family. It cannot measure a thread, establish pressure, or prove that a part belongs on your appliance. Manufacturer references are linked below each example.

Confirm every one of these

  • The cylinder valve and appliance instructions name the same connector family.
  • The regulator pressure and flow match the appliance.
  • The appliance-end fitting, hose length, routing, and safety listing also match.
