Frequently Asked Questions
What is a copper x female NPT reducing adapter used for?
It connects copper tube to a different-size male-threaded pipe, valve, fitting, equipment connection, or other compatible component.
How are the sizes listed?
The first size is the copper sweat connection, and the second size is the female NPT threaded connection.
Which end connects to copper tube?
The copper sweat socket fits over properly sized copper tube and is soldered in place.
What connects to the threaded end?
The female NPT end accepts a compatible male NPT pipe, nipple, valve, fitting, or equipment connection.
Can the female NPT connection be larger than the copper connection?
Yes. Several available configurations have a female NPT connection that is larger than the copper sweat connection. Confirm both connection sizes before ordering.
How is this adapter installed?
The copper end is soldered to prepared copper tube. The threaded end is assembled with a compatible male NPT component using an approved thread sealant.
Should the threaded joint be assembled before soldering?
The installation sequence depends on the application. Avoid overheating thread sealants, valves, seals, equipment, or other temperature-sensitive components during soldering.
Is this a domestic copper fitting?
Yes. This product is listed as a domestic wrot copper pressure fitting.
Who manufactures this adapter?
This product is manufactured by Cello Products.
Can this adapter be used in potable-water systems?
It may be used in compatible potable-water systems when installed according to applicable codes, standards, manufacturer requirements, and approved joining procedures.
Is this the same as a male adapter?
No. This product has internal female NPT threads. A copper male adapter has external male NPT threads.
