Medium-Pressure Pipe Fittings for Joining Dissimilar Metals
Use these unions to connect different metals in a piping or plumbing system. They have a plastic sleeve that inhibits destructive corrosion. Use them for connections that must be electrically insulated. Unions separate into three pieces for access to your line.
Copper tube size is the accepted designation of the copper tubing industry, not the actual tube OD.

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.

- For Use With: Drinking Water
- Tubing: Use with K, M, L copper
- Specifications Met: See table

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.
