Sweat Adapter for Air, Gases and Water

This NIBCO 6042 straight adapter joins a 3/4 inch copper tube to a 3/4 inch male pipe thread. The wrot copper body handles potable water, air and gas lines in residential and light commercial plumbing systems.

Replaces Separate Fitting Combinations

A single straight adapter removes the need for a separate coupling and threaded nipple when transitioning from sweat to MNPT connections. The jump is worth it whenever a leak-free, one-piece joint speeds up installation and reduces potential failure points.

Suits Installers Needing 466 psi at 200°F

Plumbers and HVAC technicians who require a pressure rating of 466 psi at 200 degrees Fahrenheit and a maximum temperature of 400 degrees Fahrenheit will find this fitting appropriate. Builders who need a different connection type, a reducing size or a non-copper material should look at other fittings.

Questions about this item

Will the 3/4" FTG sweat end accept a 7/8" OD copper tube?

Yes, the fitting side A is sized for 3/4" copper tube which has a 7/8" outer diameter.

How do I correctly solder the FTG end to copper pipe?

Clean both surfaces, apply flux, insert the tube fully into the fitting socket, then heat evenly and feed solder until the joint is filled.

When should I replace this adapter in a potable water system?
