Cleaned and Bagged Solder-Connect Fittings for Copper Tubing
- For Use With: Drinking Water
- Temperature Range: 32° to 200° F
- Tubing: Use with K, M, L copper
- Specifications Met: ASME B16.22, MSS-SP104, NSF/ANSI 61
When cleanliness is crucial to your application, choose these fittings that are individually cleaned and bagged to prevent contamination. Solder the socket end 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. They meet NSF/ANSI 61 safety standards for use with drinking water systems.
Copper tube size is the accepted designation of the copper tubing industry, not the actual tube OD.
