Straight Copper Adapter for 1-1/2 in Tubing

This NIBCO 90127 straight adapter joins 1-1/2 inch copper tube using a FTG connection on one end and a solder-joint connection on the other. It is built from wrot copper and rated for air or potable water systems. The fitting meets ASME B16.29, ASTM B75 and ISO 9001 standards.

Verify Tube Size and Joint Type Before Installing

Confirm that both pipe ends measure 1-1/2 inch copper tube size with a 1-5/8 inch outer diameter. One side requires a FTG fit while the other needs a solder joint, so prepare flux and solder for the SJ end. The maximum operating pressure is only 5 psi, so ensure the system design stays within that limit.

Rated for Continuous Heat Up to 400 Degrees F

The adapter handles sustained temperatures up to 400 degrees Fahrenheit without degrading. At the low 5 psi pressure rating it remains stable during long heating cycles typical of hydronic or low-pressure steam lines. Wrot copper construction resists corrosion over extended service life.

Questions about this item

Does the 90127 adapter include solder or flux, or must they be purchased separately?

The box contains only the straight adapter; solder, flux and any pipe preparation materials are sold separately.

Is the 1 1/2 inch copper straight adapter the only size offered under this part number?

Yes, part 90127 is a single straight adapter with 1 1/2 inch copper tube size on both the FTG and SJ ends.

What does the 5 psi maximum operating pressure mean for a typical residential water line?

The 5 psi rating limits this fitting to very low pressure applications such as drainage or vent lines, not standard household water supply.
