Brazing Ends: These ends are available on brass valves. The ends have a special shape to facilitate use of brazing alloys. These valves are used for higher tempera tures than solder end valves. 4. Solder Ends: For use with copper tubing in plumbing, heating and air condi tioning. Should not be used at high temperatures. 5. Flared Ends: For use with light wall tubing--either metal or plastic--and for Table 11.

The brass used in valves is similar to that used in brass pipe and contains some tin and lead as well as copper and zinc. Table 11.

A flaring tool flares the tube end, and a ring nut pulls the flared tubing up against a seat on the valve. This makes a lap joint. 6. Hub Ends: Generally used for water supply and sewage piping. This type joint is used with cast iron pipe. The joint is a socket type made by inserting the pipe in the hub, then caulking with oakum. After caulking, the joint is sealed with molten lead. Valves are made of brass, iron, steel, and to some extent malleable iron. Cast iron is generally provided in some alloying state, especially in the larger sizes. Cast iron is not suitable for service (above 450 F). Malleable iron, which is a cast iron heat treated to provide some ductil ity, is used to some extent, primarily in place of cast iron. Steel is used either in the cast or forged state'. For corrosive service, alloy and stainless steel are used. Steel is used for high temperature--high
