3. 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

Brass should not be used for work requiring temperatures above 550 F.
The brass used in valves is similar to that used in brass pipe and contains 5 some tin and lead as well as copper and zinc.

All dimensions given in inches.
* Actual diameter is same for sizes 1 to 12 in. and is $4 in. less than nominal for sizes 14 to 24 in.
sizes 2 in. and below. A flaring tool flares the tube end, and a ring nut pulls theflared 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.
