Copper Cap Trap for 1-1/4" Tube
The Nibco C617 is a wrot copper cap fitting designed to terminate a 1-1/4 inch tube in plumbing systems. It provides a permanent or temporary closure for drain, waste or vent lines during installation or repair. The fitting uses a standard copper connection method suitable for soldering or brazing. It meets ASME/ANSI B 16.22 dimensional and material standards.
Pressure Rating and Temperature Range
The cap withstands a maximum working pressure of 439 psi at 100 degrees Fahrenheit. It operates continuously across a temperature range from -20 degrees to 400 degrees Fahrenheit. Copper construction resists corrosion and handles thermal cycling without degradation. No moving parts or seals eliminate noise and leakage points under normal conditions.
Standards Compliance and Use Cases
Conformance to ASME/ANSI B 16.22 ensures dimensional compatibility with other standard copper fittings and tubing. The fitting simplifies system pressure testing by sealing open ends without additional components. It is not intended for applications exceeding the rated pressure or temperature limits. Installers requiring different tube sizes must select the corresponding model.

Questions about this item
How is the 1-1/4 in wrot copper cap installed on the tube, and what step do people often miss?
Clean the tube end and fitting socket, apply flux, insert the tube fully, then heat the joint evenly until solder flows completely around the cup; skipping the full insertion or uneven heating causes leaks.
What maintenance or replacement will the copper cap need over time?
The copper cap itself requires no scheduled maintenance; inspect solder joints periodically for corrosion or stress cracks and replace the fitting only if a joint fails or the system is altered.
What is the first limit reached under sustained high-temperature use?
The temperature ceiling of 400 degrees F is reached before the 439 psi pressure rating at 100 degrees F, so thermal limits govern sustained hot-water or steam service.
