Nibco B036500 – Frequently Asked Questions
1) What does the Nibco 704-H hose adapter connect to on each end?
One end is a solder cup that sweats onto copper tube, the other is 3/4 inch male hose thread. That is the whole point of the 704-H: it takes a soldered copper line and turns it into a garden-hose thread connection for a hose bibb outlet, drain point, or temporary hose hookup. The end configuration is C x Hose.
2) Can I use the Nibco 704-H on a potable drinking water line?
No. Use of this fitting in U.S. drinking water applications is prohibited after January 3, 2014. It is a cast bronze body to ASTM B584 Alloy C84400, which is not a lead-free potable alloy under current rules. Keep it to non-potable duty such as irrigation, HVAC and heating drops, industrial service, or fire protection. For a potable hose connection you need a lead-free rated adapter instead.
3) Is the Nibco 704-H made of copper or bronze, and does that matter for well or irrigation water?
It is cast bronze, not wrought copper. The alloy is ASTM B584 C84400 and it is dezincification resistant, which matters on irrigation and raw water systems where aggressive water can leach zinc out of ordinary brass and leave a porous, leaking fitting. Material and workmanship follow ASME B16.18.
4) Do I solder the 704-H adapter or thread it in?
Both, one end each. The copper side is a sweat joint, so it gets fluxed and soldered like any pressure fitting, and the hose side is threaded male hose thread that a hose, cap, or female hose swivel screws onto. Solder the joint first, before you hang anything with a gasket on the hose end, so you are not putting torch heat near a washer.
5) What jobs is the Nibco 704-H hose adapter typically used on?
Commercial and residential plumbing, heating and HVAC, industrial piping, irrigation, and fire protection systems, subject to the non-potable restriction. Common uses are hose-thread drain or fill points on boilers and hydronic loops, mechanical room flush connections, and irrigation hose takeoffs off a 1/2 inch copper line.
6) Is the 704-H a straight-size adapter or a reducer?
It is classed as a straight size threaded hose adapter, meaning the nominal tube size is not stepped at the solder cup. The 3/4 inch hose thread is simply the standard garden hose thread size, not a bushing or reduction in the copper line.
7) What is the Nibco part number for the 1/2 inch 704-H hose adapter?
The 1/2 inch cast bronze 704-H C x Hose adapter carries Nibco part number B036500. Quote that number if you are standardizing a mechanical room or matching fittings already installed.
