The Foster \u003cstrong\u003e3L54\u003c\/strong\u003e is a 3\/8\" plug from the 3FRL Series, which interchanges with Hansen 3\/8\" 3RL couplers. It uses an automatic push-to-connect ring-lock design with high flow capacity — and critically, will not disconnect when the hose is dragged across the ground.
