Review on Manchester Tank S33250: Durable Plastic POL Plug for Propane Gas Tanks by John Akins

Doesn't fit. I have used POL threaded propane for many years. This connector just doesn't fit. It crosses threads easily and is small, making it difficult or impossible to make gas tight. It just doesn't work as intended and the seller should destroy the whole lot as I feel they pose a security risk. I've attached a picture of another POL fork for comparison. Blue fits, red doesn't. You can see the difference. It also costs more than it should. Some propane vendors will provide you with a matching bottle free of charge. I have requested and received a refund.
