Solder-Connect Fittings for Copper Tubing

Temperature Range: 32° to 200° F

Solder these fittings to copper tubing or the tube end of another fitting for a permanent, leak-tight connection. They are also known as sweat fittings. Fittings have good corrosion resistance. To adhere to safety standards for drinking water systems, use fittings that meet NSF/ANSI 61 or EN 1057.

Copper tube size is the accepted designation of the copper tubing industry, not the actual tube OD.
