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.

- For Use With: Air, Water, Oil, Natural Gas
- Max.Temperature: 180° F
High-Pressure Brass Threaded Pipe Fittings
These fittings have the strength to handle high-pressure applications. They are brass for good corrosion resistance.
Union connectors separate into three pieces so you can access your line without unthreading pipe connections.
NPTF (Dryseal) threads are compatible with NPT threads.

High-Pressure Brass Threaded Pipe Fittings for Drinking Water
Use these heavy duty fittings for high-pressure drinking water applications. They are brass which has good corrosion resistance. They meet NSF/ANSI 61 safety standards for use with drinking water systems.
Union connectors separate into three pieces so you can access your line without unthreading pipe connections.
NPTF (Dryseal) threads are compatible with NPT threads.

Low-Pressure Brass and Bronze Threaded Pipe Fittings
Use these fittings in low-pressure flow applications. They have good corrosion resistance. Fittings rated for use with drinking water meet NSF/ANSI 61 safety standards.
Union connectors separate into three pieces so you can access your line without unthreading pipe connections.

Low-Pressure Plated Brass Threaded Pipe Fittings
Used in low-pressure pipe lines, these brass fittings have a plating that makes them shiny and improves corrosion resistance.
Chrome-plated brass fittings are shinier and withstand corrosion better than nickel-plated brass fittings.
Union connectors separate into three pieces so you can access your line without unthreading pipe connections.
