Pipe sleeves are <strong>a metal covering that fit over your copper pipes that comes out of the floor and go into your radiator</strong>. 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 <strong>to protect the pipe and insulation from chafing</strong>. The sleeve operates by putting gentle pressure on the outer skin surface. This has the effect of <strong>subtly increasing blood pressure in the arms, which helps increase the flow of blood throughout the body</strong>.
