Flush 4" (101.6 mm) NPT x 3" (76.2 mm) NYFD x 3" (76.2 mm) NYFD Cast Brass "Standpipe" Fire Department Connection (FDC) saves lives and property when closed valves, natural disasters, pressure loss, or other problems interrupt the supply of water to standpipe systems. With a double-clapper design, cast brass finish, and solid brass components, this UL & ULC-listed FDC supports firefighting efforts by providing local fire officials with inlets used to pump water to fire sprinklers or in-building hose connections when primary water sources, such as a water supply tank, are exhausted.
Each Flush 4" (101.6 mm) NPT x 3" (76.2 mm) NYFD x 3" (76.2 mm) NYFD Cast Brass FDC is sold as a kit containing an NPT x NPT body (NPT inlets with an NPT outlet), two open adapters with 2 1/2" (63.5 mm) rigid NPT x 3" (76.2 mm) NYFD hose thread, two NYFD-threaded brass plug and chain assemblies, and a polished brass "Standpipe" identification plate. Inlet swivels utilize National Standard Thread (NST) and connect easily to fire hose connections throughout much of the United States.
This Flush 4" (101.6 mm) NPT x 3" (76.2 mm) NYFD x 3" (76.2 mm) NYFD Cast Brass "Standpipe" FDC is available in a straight (back outlet) orientation or in a 90-degree angled orientation (bottom/top outlet) for easy connection to existing piping. The bulk of a flush fire department connection typically installs behind an exterior wall, providing a lower-profile design than that of an exposed or freestanding connection. The National Pipe Thread (NPT) outlet installs to a wide range of plumbing and pipe fittings across the United States to streamline replacement of a broken, corroded, or unserviceable FDC.
When ordered with a Back Outlet (angled) orientation, this FDC's body is 11.81" (30 cm) wide, 5.19" (13.1 cm) tall, and 7.63" (19.4 cm) deep. When ordered with a Top/Bottom orientation, this FDC's body is 11.81" (30 cm) wide, 7.06" (18 cm) tall, and 6.25" (15.9 cm) deep. These dimensions apply to the body only and are not an accurate indication product's full size after the installation of open adapters, plug and chain assemblies, and the identification plate.
This Flush 4" (101.6 mm) NPT x 3" (76.2 mm) NYFD x 3" (76.2 mm) NYFD Cast Brass "Standpipe" FDC is ready for use with sprinkler systems in schools, high-rise buildings, apartment complexes, manufacturing facilities, and a wide range of other NFPA-compliant buildings. "Standpipe" signage suitably marks this FDC for use with standpipe systems designed and installed in accordance with NFPA 13 and NFPA 14. The accompanying identification plate is 15" (38.1 cm) wide, 9" (22.86 cm) tall, and 4 1/2" (11.43 cm) from inlet hole center to plate top, with letters 1" (25mm) or larger cast on the polished-brass plate.
Each 3" (76.2 mm) inlet can supply up to 250 gallons per minute (GPM), allowing this Flush 4" (101.6 mm) NPT x 3" (76.2 mm) NYFD x 3" (76.2 mm) NYFD Cast Brass "Standpipe" FDC to deliver a total supply of up to 500 GPM.Two independent, self-closing brass clapper valves prevent backflow while allowing water to flow in from both inlets simultaneously.
This Flush 4" (101.6 mm) NPT x 3" (76.2 mm) NYFD x 3" (76.2 mm) NYFD Cast Brass "Standpipe" Fire Department Connection is also suitable for use with Class I automatic wet standpipes and Class III standpipe systems, found in underground buildings, concert halls, malls, marinas, and other structures. Buildings requiring flows greater than 500 gallons per minute in accordance with NFPA 13 and NFPA 14 will need additional inlets, provided by additional single or double-inlet FDCs, or by installing a three-way, four-way, or six-way FDC.
