About Pipe and Fittings

Measure your pipe and fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.

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.

Straight Connectors with Center Stop, Female Socket-Connect Tube

For Use With: Drinking Water
Tubing: See table
Specifications Met: See table

Fittings with center stop have a small internal ridge that prevents the tubing from sliding all the way through the fitting.

Fittings that meet ASTM B379 comply with international standards for tube fitting specifications.
