Nibco, Inc. C601 1 in copper coupling without stop

SKU CH-N50P-2WWJ9 MPN C601

A 1-inch wrot-copper drain coupling without a stop, rated to 494 psi at 100 degrees F and compliant with ASME/ANSI B 16.22

  • TypeDrain Components
  • Wrought copper construction resists corrosion for long service life
  • Stop-free design allows full flow through the joint
  • Rated 494 psi at 100 degrees F for high-pressure systems
  • Operates from -20 to 400 degrees F across wide temperature range
  • Meets ASME/ANSI B 16.22 standard for reliable installation

Copper coupling for 1 in tube

The Nibco C601 is a wrot copper coupling designed to join two lengths of 1 in copper tubing in plumbing and drainage systems. It serves installers who need a straight, solder-type connection without an internal stop so tubes can pass completely through the fitting.

C x C solder connection without stop

The fitting uses a C x C connection type, meaning both ends accept copper tube for sweat soldering and there is no centre stop to limit insertion depth. This single specification determines whether the part matches the joint design required on the job.

Pressure and temperature performance

The coupling is rated for a maximum working pressure of 494 psi at 100 degrees F and operates continuously across a temperature range of -20 degrees to 400 degrees F. These limits define its behaviour under sustained system load rather than a brief test spike.

Questions about this item

How does the 494 psi pressure rating hold up once the coupling is installed in a live plumbing system?

The coupling is rated for 494 psi at 100 °F, so it will handle typical residential and commercial water pressures well within that limit.

What does the ASME/ANSI B 16.22 standard cap in practice for this copper coupling?

ASME/ANSI B 16.22 governs dimensions and tolerances for wrought copper solder-joint fittings, ensuring the 1 in tube size and 1-1/8 in outside diameter match compatible piping.

What pipe size and clearance does this coupling need to fit and mount correctly?

It fits 1 in nominal copper tube with a 1-1/8 in outside diameter and uses a straight C x C solder connection, so allow enough straight pipe length for proper joint insertion.
