A method for manufacturing a tube fitting includes steps of: preparing the tube fitting; and forming a resin coating layer upon a coated region provided upon the surface of the tube fitting. Forming the resin coating layer includes: dipping the tube fitting into a coating material that includes as components a polyethylene based substance, a lubricant, and solid particles and having viscosity within a range of 4.24 to 5.27 mPa.Math.s at 25? C., and adhering the coating material to the coated region; and, drying the coating material which is adhered to the coated region of the tube fitting. In the dipping step, the mass per unit area w is controlled within a range 0.79<w<10.07 by dipping the tube fitting while regulating a temperature of the coating material within a range of 30? C. to 40? C.

Provided are a gas processing system, a control method thereof, and an electrical device. The gas processing system includes: a gas storage container, a controller, and a switch component. The gas storage container has a first gas flow branch configured for communicating with a battery box and supplies a dry gas to the battery box. The controller can acquire a state parameter of a gas in the battery box. The switch component is arranged on the first gas flow branch and can switched between a first state, in which the first gas flow branch is turned on, and a second state, in which the first gas flow branch is blocked. The controller is in communication connection with the switch component, and can control the switch component to be switched from the second state to the first state when the state parameter of the gas acquired satisfies a preset condition.

The invention relates to a system (400) comprising a vehicle (402), an arm assembly (408), first and second cable portions (410a, 410b), at least one cable actuator (406), and an air supply line. The vehicle has a pneumatic source of pressurized air. The arm assembly has an end effector releasably coupled to an end of an axially-extendable arm coupled to the vehicle. The end effector has a gladhand coupling portion. The air supply line can be coupled to the end effector and can deliver pressurized air from the pneumatic source to a braking system of the trailer when the gladhand coupling portion is coupled to the gladhand receptacle of a trailer. After coupling to the gladhand receptacle, the end effector can be disconnected from the arm assembly to allow the remainder of the arm assembly to be stowed.

A brake system for actuating front and rear wheel brakes includes a reservoir and a master cylinder operable during a manual push-through mode by actuation of a brake pedal to generate brake actuating pressure at a first output for hydraulically actuating the pair of front wheel brakes. A power transmission unit is configured for selectively providing pressurized hydraulic fluid for actuating the pair of front wheel brakes and the pair of rear wheel brakes during a braking event. First and second two-position three-way valves are provided. Each three-way valve is hydraulically connected with the master cylinder, the power transmission unit, and a selected one of the front wheel brakes. Each of the first and second three-way valves selectively controls hydraulic fluid flow from a chosen one of the master cylinder and the power transmission unit to the selected one of the pair of front wheel brakes.
