Description
3/4" Sweat x 3/4" FIP Copper Corrugated Connector
Charman Inc Copper Corrugated Water Heater Connectors provide a flexible transition between a 3/4" sweat connection and a 3/4" female iron pipe connection. The corrugated copper tube helps accommodate alignment between water heater and plumbing connection points while providing a compact, flexible alternative to rigid piping.
This connector family combines a copper corrugated tube, brass-plated brass HPb58-3 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 lengths are 12", 15", 18", and 24".

Corrugated Copper Construction
The corrugated copper tube provides flexibility between fixed connection points, helping accommodate positioning and alignment during water heater and plumbing installations. The connector transitions from a 3/4" sweat connection to a 3/4" FIP connection while maintaining a 2.5" minimum bend radius.
Brass-plated brass fittings, machine solid brass nuts, and an EPDM gasket complete the connector assembly.

All four variants use the same 3/4" Sweat x 3/4" FIP connection configuration. Select the required connector according to the installation distance and routing requirements.
Understanding the Connection Configuration
3/4" Sweat Connection
The sweat end is designed for joining to compatible 3/4" copper tubing using an appropriate soldered connection method.
3/4" FIP Connection
The FIP end provides a 3/4" female threaded pipe connection designed to mate with a compatible 3/4" male pipe thread.
Choosing the Correct Length
Measure the distance and planned routing between connection points before selecting a connector. Choose a 12", 15", 18", or 24" length that provides adequate routing without placing excessive tension, compression, or distortion on the corrugated tube.
Maintain 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" Sweat x 3/4" FIP.
- Verify that the sweat end is compatible with the copper tubing being installed.
- Verify that the FIP connection mates with a compatible 3/4" male threaded connection.
- Select the appropriate connector length for the installation distance and routing.
- 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.
- Protect the connector and surrounding components from excessive installation heat.
- Align threaded connections carefully to avoid cross-threading.
- Use sealing practices appropriate for threaded plumbing connections.
- 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" sweat connection on one end and a 3/4" female pipe-thread connection on the other.
Length & Routing
Select the 12", 15", 18", or 24" variant according to the required installation distance. Maintain the 2.5" minimum bend radius and avoid unnecessary stress on the connector.
