Understanding the Connection Configuration
1-1/4" FIP Connection
One end provides a 1-1/4" female threaded pipe connection designed to mate with a compatible 1-1/4" male threaded connection.
1" FIP Connection
The opposite end provides a 1" female threaded pipe connection designed to mate with a compatible 1" male threaded connection.
Available Connector Lengths
- 18" - SKU 173718
- 24" - SKU 173724
Both variants use the same 1-1/4" FIP x 1" FIP connection configuration. Select the required length according to the installation distance and routing requirements.
Choosing the Correct Length
Measure the required connection path before selecting a connector. Choose an 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.

Installation & Selection Guidance
- Confirm that the required configuration is 1-1/4" FIP x 1" FIP.
- Verify that the 1-1/4" FIP end mates with a compatible 1-1/4" male threaded connection.
- Verify that the 1" FIP end mates with a compatible 1" male threaded connection.
- Select the appropriate 18" or 24" connector length.
- Maintain a minimum bend radius of 2.5".
- Do not sharply bend, kink, crush, or twist the corrugated tube.
- Inspect the connector, fittings, threads, and gasket before installation.
- Align threaded connections carefully to avoid cross-threading.
- 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.
