They're a fantastic way of supercharging your radiator valves and making them look even more stylish. A sleeve is a section of pipe that is placed in a wall or partition for the passage of piping. As the pipe expands and contracts in its thermal cycle, the purpose is to protect the pipe and insulation from chafing. The sleeve operates by putting gentle pressure on the outer skin surface. This has the effect of subtly increasing blood pressure in the arms, which helps increase the flow of blood throughout the body.
