Nibco, Inc. 601 2 1/2 Copper Coupling Trap

SKU CH-S4J6-1STTM MPN 601

A 2-1/2 inch wrot copper coupling joins tubes without an internal stop and handles up to 336 psi at 100 degrees Fahrenheit

  • Product typeDrain Components
  • Wrot copper construction resists corrosion for long service life
  • Coupling without stop allows straight-through flow in drain lines
  • Rated to 336 psi at 100 degrees F for reliable pressure handling
  • Operates from -20 to 400 degrees F across wide temperature range
  • Meets ASME/ANSI B 16.22 standard for code-compliant installations

Copper Coupling 2-1/2 Inch

This wrot-copper coupling joins two 2-1/2 inch tubes in a straight C x C connection without an internal stop. It is intended for plumbing professionals and installers who need a permanent sweat joint in copper drainage systems. The fitting meets ASME/ANSI B 16.22 standards for material and dimensions.

Stop-Free Design

Because the coupling lacks a centre stop, the two tubes can slide fully through each other before soldering, giving the installer flexibility to adjust insertion depth on site. This simplifies repairs where exact pipe lengths are difficult to pre-measure and speeds up assembly in tight spaces.

Pressure Rating 336 psi at 100 Degrees F

The fitting is rated for a maximum working pressure of 336 psi at 100 degrees Fahrenheit and a continuous temperature range of -20 to 400 degrees Fahrenheit. Systems operating above these limits require a different component.

Questions about this item

Will the wrot copper coupling need replacement if the system pressure exceeds 336 psi at 100 Degrees F?

The coupling is rated for a maximum of 336 psi at 100 Degrees F; sustained pressure above that limit can cause failure and would require replacement of the fitting.

What is the first limit reached when the fitting runs continuously at the top of its temperature range?

The temperature ceiling is 400 Degrees F; at that point the pressure rating drops and the copper approaches its thermal limit, so temperature is the governing constraint.

Does the 2-1/2 inch copper coupling generate noise or heat when water flows through it all day?

The fitting has no moving parts and adds no measurable noise; it simply conducts the fluid temperature, so heat output matches the water temperature up to 400 Degrees F.
