VIEW SPEC SHEET
USAGE
Fire Threaded Fittings are mainly used to connect to fire hydrants, fire hoses, reduce or increase thread sizes and convert from one thread type to another.
TERMINOLOGY
Fire Threaded Fittings can also be referred to as Double Females, Doubles Males, Reducers, Increasers, Caps and Plugs. On both the female and male ends, NFC supplies all threaded fittings with a higbee cut, which makes them thread much smoother and without the possibility of cross-threading. A higbee is also known as a quick start thread and indicates the start of the fire thread. The start of the higbee cut thread will also line up with the notch found on the outside of the rocker lug on fittings.
Forging is a manufacturing process involving the shaping of metal using localized compressive forces. The blows are delivered with a hammer (often a power hammer) or a die.
MATERIAL
Made from forged 6061-T6 lightweight aluminum alloy. NFC offers top quality Hard Black Anodized Threaded Fittings ranging from 1 ½” to 6”. The finished product is laser engraved with a clear understanding of the thread type and size produced. Swivel sizes ranging from 1 1⁄2” to 3” are attached using Stainless Steel ball bearings. Swivel sizes ranging from 4” to 6” are attached using aluminum roller bearings.
THREADS
NFC stocks all Canadian Provincial Fire Threads. Standard threads include BAT, WCT, CSA, QST, NSZ1, NH, NPSH.

INSTRUCTIONS FOR MEASURING THREADS
If a thread gauge and caliper are not available, and a sample cannot be sent, the following method can be used to obtain the correct outside diameter and pitch of the thread needed.
- Cut a strip of paper about 1"(25mm) wide, long enough to wrap tightly around the circumference of the male thread and overlap at the ends.
- With a pin, pierce through both layers of the paper (fig.1).
- Press your thumb firmly against the thread hard enough to make a thread impression on the strip (fig. 2).
- Remove the strip and circle the pin holes on the strip with a pencil (fig. 3).
- Divide the distance between the pin holes by 3.1416. The result is the ODM (outside diameter of the male).
It is important that both the ODM and threads per inch (pitch) of the male part are given when ordering. Always include the paper strip with your correspondence. If not specified, "V" sharp thread will be furnished.
GASKETS
High quality swivel gaskets are lathe cut ozone free EPDM.
