304 Stainless Steel CSST Construction
The corrugated tube is constructed from 304 stainless steel to ASTM A240. Its corrugated design provides flexibility between fixed connection points, helping accommodate positioning and alignment during water heater and plumbing installations.
Chrome-plated brass HPb58-3 fittings and a high-quality EPDM gasket complete the connector assembly. The connector is designed to maintain controlled flexibility while observing the specified 2.5" minimum bend radius.

All four variants use the same 3/4" FIP x 3/4" FIP connection configuration. Select the required connector according to the installation distance and routing requirements.
Understanding the Connection Configuration
This connector has 3/4" FIP connections on both ends. Each female threaded pipe connection is designed to mate with a compatible 3/4" male threaded connection.
Because the connection configuration remains the same across the family, the primary difference between the four variants is overall connector length.
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 stainless steel tube.
Maintain the specified 2.5" minimum bend radius and avoid sharp bends, kinks, crushing, or twisting during installation.

Review the Stainless Steel Water Heater Connector specification sheet for product, pressure, temperature, and dimensional information, or use the Charman Inc catalog to compare available connector sizes, lengths, and configurations before ordering.
Installation & Selection Guidance
- Confirm that the required connection configuration is 3/4" FIP x 3/4" FIP.
- Verify that both FIP connections mate with compatible 3/4" male threaded connections.
- 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 stainless steel tube.
- Inspect the connector, fittings, threads, 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 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
Both ends use 3/4" FIP connections. Confirm that both mating connections provide compatible 3/4" male pipe threads before ordering.
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.
