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.

A computer controlled brake that can selectively operate the 13 control portion exhaust magnet valve to couple the 13 pipe to atmosphere and the 20 control portion lead/trail magnet valve to pressurize the 20 pipe pressure of a trail locomotive in response to consist swap mode enabled while switching ends of a locomotive consist. The computer controlled brake is also configured to operate 13 control portion exhaust magnet valve to disconnect the source of 13 pipe pressure from atmosphere and to de-energize 20 control portion lead/trail magnet valve to stop pressurizing the source of 20 pipe pressure in response to sensing a rise in brake pipe from a newly established lead locomotive disabling consist swap mode.

Apparatus for guiding air toward a wheel brake of a motor vehicle. The apparatus includes an air guide element, which can be displaced between a retracted rest position, in which the same is retracted in relation to an undercarriage of the motor vehicle, and an extended operating position, in which the same is extended in relation to the undercarriage. The air guide element can be displaced, via a hydraulic adjustment mechanism between the rest position and the operating position. The hydraulic adjustment mechanism includes a hydraulic cylinder and a return element. In the presence of brake actuation, the hydraulic cylinder can be filled with brake fluid in order to displace the air guide element from the rest position to the operating position. In the absence of brake actuation, the return element displaces the air guide element from the operating position to the rest position.

A brake control system includes a trailer brake valve fluidly interposed between a vehicle brake assembly and a trailer brake assembly. A brake module is operably coupled with the vehicle brake assembly and configured to provide a first signal to the trailer brake valve. A control valve is configured to provide a second signal to the trailer brake valve. The trailer brake valve is operated based on the first signal when the vehicle is operated in a first mode and operated based on the second signal when the vehicle is operated in a second mode.
