  • Potable water approved for safe supply systems
  • Wrot copper construction resists corrosion and scaling
  • 494 psi rating handles high-pressure demands
  • 250 °F tolerance suits hot water lines
  • Straight adapter connects 1" tube to 1" FPT thread

Copper Adapter for Potable Water Systems

The Streamline W 01563 adapter connects a one-inch copper tube to a one-inch female pipe thread using a sweat fitting. It is intended for plumbers and contractors installing or repairing potable water lines in residential or commercial buildings. The wrot copper construction provides corrosion resistance for long service life.

Pressure and Temperature Performance

The fitting withstands a maximum operating pressure of 494 psi at 100 degrees Fahrenheit and a maximum operating temperature of 250 degrees Fahrenheit. These ratings support sustained hot water circulation and high-pressure supply lines without deformation or leakage. The straight adapter shape maintains consistent flow through the joint.

Thermal Stability and Installation

Wrot copper handles repeated thermal cycling from cold supply to hot water temperatures up to the rated limit. The sweat connection requires standard soldering technique with no center stop to interfere with tube insertion depth. The material does not degrade under normal potable water chemistry.

Questions about this item

How much heat can the 1" copper adapter handle during continuous potable-water service?

The wrot-copper body is rated for a maximum operating temperature of 250 Degrees F, so it remains stable in hot-water lines running all day.

What pipe and tube sizes must already be in place for this straight adapter to connect?

You need a 1 in copper tube (1 1/8 in OD) for the sweat end and a 1 in female NPT threaded pipe for the other side.

Will the 494 psi pressure rating hold when joining this adapter to older 1" copper piping?

Yes, the 494 psi @ 100 Degrees F rating applies to the wrot-copper fitting itself, matching standard 1" copper tube used in existing installations.
