  • Handles high-pressure lines with a 577 psi rating at 200°F
  • Withstands hot-water systems up to 400°F maximum temperature
  • Connects 1/2 in copper tube to 1/2 in male pipe threads
  • Wrot copper construction resists corrosion in potable water and gas lines
  • Straight adapter shape simplifies in-line sweat joint installation

Copper Sweat Adapter

The Nibco 6042 is a straight sweat fitting adapter that joins a 1/2 in copper tube to a 1/2 in male NPT thread. It is intended for plumbers and maintenance crews working with air, gases or potable water systems where a secure copper-to-threaded transition is required.

Wrot Copper Construction

The wrot copper body provides corrosion resistance and complies with potable water standards. This material choice means the fitting can handle the chemical demands of drinking water lines and the thermal cycling of hot water or gas distribution without degrading.

Pressure and Temperature Limits

Rated for 577 psi at 200 Degrees F and a maximum operating temperature of 400 Degrees F, the adapter suits high-pressure hot water or steam applications. The straight profile and matching 5/8 in outer diameters on both ends simplify alignment during soldering and threading, reducing joint stress in daily service.

Questions about this item

Will the wrot-copper body need replacement if the joint is heated above 400 Degrees F?

The fitting is rated to 400 Degrees F maximum operating temperature; exceeding that limit can degrade the copper and require replacement.

What pressure limit is reached first during sustained high-temperature service?

At 200 Degrees F the maximum operating pressure is 577 psi, so that pressure ceiling appears before the 400 Degrees F temperature ceiling.

How much heat does the adapter add to the line when water circulates all day?

The copper construction adds no active heat; it simply conducts the fluid temperature, staying within the 400 Degrees F rating during continuous operation.
