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.

- 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.
