Nibco B03110L – Frequently Asked Questions
1) How does the Nibco 704-LF male adapter connect on each end?
One end is a solder cup that sweats onto copper tube, the other is a male NPT thread. It is the fitting you use to take a soldered copper run into threaded equipment, a valve, or a threaded nipple. The threaded end is male, so it screws into a female thread.
2) What size is the Nibco 704-LF C x M adapter?
It is offered in 3/4 inch by 1-1/4 inch, which makes it a reducing adapter rather than a straight size-for-size fitting. Check both numbers against your copper tube and your threaded port before ordering, since the two ends are not the same size.
3) Can I use a Nibco 704-LF bronze adapter on a heating or fire protection line, or is it potable water only?
Nibco lists it for commercial plumbing, fire protection, heating, HVAC, industrial, irrigation, and residential plumbing. It is a general purpose solder pressure adapter, not restricted to potable water.
4) What design standard does the Nibco 704-LF copper adapter meet?
It is built to ASME B16.18, the standard for cast copper alloy solder joint pressure fittings, so it mates with standard copper tube solder joints. Manufactured in an ISO 9001 certified facility.
5) Why choose a bronze male adapter instead of a wrought copper one for a threaded connection?
Threads take wrench torque, and the cast silicon bronze body handles that better than thin wrought copper. The Performance Bronze alloy is also dezincification resistant, which matters where water chemistry attacks brass threads over time.
6) Do I solder the Nibco 704-LF adapter before or after threading it in?
Solder the copper cup first with the fitting off the threaded connection wherever you can. Heat carried into an assembled joint can damage thread sealant or nearby valve seats. Nibco publishes copper fittings installation instructions covering joint prep and heating; follow those for the solder end.
