Nibco B035650 – Frequently Asked Questions
1) What kind of connection does the Nibco 704-2-H hose adapter make?
It goes from a solder joint to a hose thread. The 704-2-H has a male solder (fitting/street) end that slips inside a copper fitting socket, and a male hose thread on the other end, so you can run a garden hose or washing machine hose off a copper line. End connection type is Ftg x Hose.
2) Does the Nibco 704-2-H solder into a copper fitting or over the pipe?
Into the fitting. It's a fitting end (street), meaning that end is sized like the outside of copper tube and drops into the socket of an elbow, tee, or valve. It will not slip over the end of a pipe. If you need to join onto a cut pipe end instead, you want a C x Hose adapter rather than an Ftg x Hose.
3) Can I use the Nibco 704-2-H on a drinking water line?
No. Use of this fitting in U.S. potable drinking water applications is prohibited after January 3, 2014. It is a C84400 bronze body, which is not a lead-free alloy. Keep it to non-potable duty, hose bibb service off a non-potable line, irrigation, HVAC, or industrial. For potable work you need a lead-free alloy adapter.
4) What size is the Nibco 704-2-H hose adapter?
3/4 inch, MPN B035650. That is the solder side. It's also catalogued as a reducing-size adapter, so the solder end and the hose thread end are not the same nominal size.
5) What systems is the Nibco Ftg x Hose bronze adapter approved for?
Nibco lists it for commercial plumbing, fire protection, heating, HVAC, industrial, irrigation, and residential plumbing. The one hard exclusion is U.S. potable drinking water after January 3, 2014.
6) Does the hose end on the Nibco 704-2-H need a washer or tape?
It's a male hose thread, so it seals on a gasket, not on the threads. The hose or the female fitting you screw onto it carries the washer. Tape on a hose thread does nothing. The solder end is a sweat joint, so you'll want flux and solder for that side.
7) Will the Nibco 704-2-H stand up to water that eats up brass fittings?
The bronze body is dezincification resistant, which is the failure mode that cracks ordinary high-zinc brass in aggressive or chlorinated water. Alloy is ASTM B584 C84400, with material and workmanship to ASME B16.18.
8) Is the Nibco 704-2-H a wrought or cast fitting?
Cast bronze, not wrought copper. That matters on a hose adapter because the hose end takes wrenching and side load from a coupled hose, and a cast bronze body handles that better than a thin wrought copper wall. It's poured to ASTM B584 C84400.
