Copper Reducing FNPT Adapter

This 2" x 1-1/2" copper adapter connects a copper pipe to a female NPT thread in residential plumbing. It suits installers who need a reliable reducing transition between dissimilar pipe sizes. The transparent finish allows visual confirmation of solder flow during assembly.

Sustained joint integrity

The copper construction resists corrosion and handles continuous water pressure without degradation. It maintains a leak-free seal through thermal cycling and vibration typical in supply lines. No maintenance is required after proper installation.

Reducing C x FNPT configuration

This fitting only works where a 2" copper pipe must step down to a 1-1/2" female thread. It cannot join two copper pipes directly or connect to a male thread. Verify both diameters before purchase.

Questions about this item

Will this adapter generate any noise or heat during continuous plumbing use?

As a passive copper fitting with no moving parts or electrical components, it produces no operational noise or heat.

What existing pipe and thread types must I already have for this 2" x 1-1/2" C x FNPT adapter to connect?

You need a 2-1/8" OD copper pipe for the sweat end and a 1-1/2" male NPT threaded fitting for the female threaded end.

Can this reducing adapter join older copper pipe with existing 1-1/2" NPT threaded components?

Yes, the sweat end accepts 2" nominal copper tube and the FNPT end mates with standard 1-1/2" NPT threads on legacy fittings.
