Description
3/4" FIP x 3/4" PEX Copper Corrugated Connector
Charman Inc Copper Corrugated Water Heater Connectors provide a flexible transition between a 3/4" female iron pipe connection and a 3/4" PEX connection. The corrugated copper tube helps accommodate alignment between water heater and piping connection points while maintaining a compact, flexible installation.
This connector family combines a copper corrugated tube, brass-plated brass fittings, machine solid brass nuts, and a high-quality EPDM gasket. It is rated for working pressures up to 125 PSIG, intermittent impulse pressures up to 180 PSIG, and temperatures from -40°F to 180°F. Available 18" and 24" lengths allow the connector to be matched to the required installation distance.

Corrugated Copper Construction
The corrugated copper tube provides flexibility between fixed connection points, helping accommodate positioning and alignment during water heater and plumbing installations. Its corrugated design allows controlled routing while the 2.5" minimum bend radius helps define the amount of curvature appropriate for installation.
The connector incorporates brass-plated brass fittings, machine solid brass nuts, and an EPDM gasket to create a complete water-connection assembly.

Understanding the Connections
3/4" FIP Connection
The 3/4" FIP end provides a female threaded pipe connection and is designed to mate with a compatible 3/4" male threaded connection.
3/4" PEX Connection
The opposite end provides a 3/4" PEX connection for integration with a compatible PEX piping system. Confirm compatibility with the PEX connection method and components used in the installation.
Common Applications
Water Heater Connections
- Water heater installations
- Water heater replacements
- Hot water connections
- Cold water connections
- Equipment connection updates
Plumbing Connections
- PEX-to-threaded plumbing transitions
- Flexible equipment connections
- Residential plumbing installations
- Commercial plumbing installations
- Repair and maintenance applications
Choosing the Correct Length
Measure the distance and planned routing between the water heater or equipment connection and the PEX piping before selecting a connector. Choose an 18" or 24" length that provides adequate routing without placing excessive tension, compression, or distortion on the corrugated tube.
Maintain at least the specified 2.5" minimum bend radius and avoid sharp bends, kinks, crushing, or twisting during installation.

Installation & Selection Guidance
- Confirm that the required connection configuration is 3/4" FIP x 3/4" PEX.
- Verify compatibility with the PEX piping and connection system being used.
- Confirm the threaded connection mates with a compatible 3/4" male pipe thread.
- Select the 18" or 24" length appropriate for the installation.
- Maintain a minimum bend radius of 2.5".
- Do not sharply bend, kink, crush, or twist the corrugated copper tube.
- Inspect the connector, fittings, nuts, and gasket before installation.
- Do not install components that are visibly damaged.
- Align threaded connections carefully to avoid cross-threading.
- Use sealing practices appropriate for the threaded plumbing connection.
- Do not exceed the 125 PSIG working-pressure rating.
- Use only within the specified -40°F to 180°F temperature range.
- Check completed connections for leaks before placing the system into service.
- Follow applicable plumbing codes, equipment instructions, and local requirements.
- Installation should be performed by qualified personnel.
Product Selection Considerations
Connection Compatibility
Confirm that the installation requires a 3/4" female threaded connection on one end and a compatible 3/4" PEX connection on the other. Connection type should be verified before ordering.
Length & Routing
Choose between the 18" and 24" variants according to the required distance and routing. Maintain the 2.5" minimum bend radius and avoid unnecessary stress on the connector.
