Frequently Asked Questions

What is a NIBCO 617 1 wrot copper cap used for?

A NIBCO 617 1 wrot copper cap seals the end of 1-inch CTS copper tubing in plumbing, HVAC, and refrigeration systems. It provides a permanent, leak-proof closure for water, gas, or steam lines, ensuring system integrity during maintenance or dead-end terminations.

What are the specifications of the NIBCO 617 1 cap?

The NIBCO 617 1 is a 1-inch CTS cup-type wrot copper cap, part number 617 1. It is designed for sweat/solder connections and meets ASTM B88 standards for copper tube fittings. The wrot copper construction offers corrosion resistance and durability in industrial piping systems.
