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.
- For Use With: Drinking Water
- Tubing: Use with K, M, L copper
- Specifications Met: ASME B16.22, MSS-SP104, NSF/ANSI 61
