Safety Bump cam lock plugs provide a handle for the operator to lift and drag the hose assembly from. They incorporate an over-sized body that protects the coupling from damage when it is dropped or knocked into. When the hose is dropped on the ground the Safety bump cap or plug makes contact rather than the hose coupling. This also protects the hose tray of a tank hauler as the plastic makes contact and not the metal coupling or loose cam arm. Safety Bumps cap off your hose assemblies just like a standard dust cap or plug to prevent leaks and drips when a hose is in transport or storage.
