What type of threads are found on the POL valve?

  1. Right-handed threads

  2. Left-handed threads

  3. Standard threads

  4. Pipe threads

The correct answer is: Left-handed threads

The POL (Prest-O-Lite) valve, commonly used in propane tanks, is designed with left-handed threads. This particular threading is intentionally implemented to mitigate the risk of accidental disconnection from other fittings or connections that use standard right-handed threads. By using left-handed threads, the POL valve effectively ensures that the connection can only be tightened or released in one specific orientation, which enhances safety during propane use. Understanding the threading type is crucial for RV technicians, as it affects how connections are made and the compatibility with various equipment. When doing maintenance or repairs, recognizing that POL valves employ left-handed threads helps prevent mishaps that could arise from incorrect installations or attempts to connect fittings improperly.
