Charlotte Pipe nh-12 No-hub Cast Iron Edge Hp Long 1/8 Bend 45 Degree 4 Inches X 4 Inches

Product Description

The Charlotte Pipe nh-12 is a No-Hub Cast Iron Edge HP Long 1/8 Bend designed for use in sanitary drain, waste, and vent (DWV) systems, as well as sewer and storm drainage applications. This fitting delivers a 45-degree directional change in cast iron drain lines where a gradual, long-radius turn is required. It is a go-to choice for licensed plumbers, drain contractors, and mechanical trade professionals working on commercial and residential below-grade or above-grade drainage systems. The nominal pipe size is 4 inches on both ends, making it compatible with standard 4-inch no-hub cast iron pipe and fittings. The no-hub connection style means it joins to mating pipe and fittings using no-hub couplings with stainless steel bands and neoprene gaskets, allowing fast and secure field assembly without the need for lead and oakum or hub-and-spigot jointing. Cast iron is the preferred material for drain, waste, and vent piping in multi-story buildings, hotels, hospitals, and schools because it resists corrosion, deadens sound compared to plastic pipe, and handles high temperatures. This fitting carries a maximum temperature rating of 212 degrees Fahrenheit, covering standard hot-water drainage and steam condensate service. It meets ASTM 888 and CISPI Standard 301, which are the governing standards for hubless cast iron soil pipe and fittings. It is also NSF Certified and manufactured under an ISO 9001:2015 quality management system, confirming consistent dimensional accuracy and material quality. The black finish is standard for cast iron soil fittings. The long 1/8 bend configuration provides a smoother flow path than a short-radius bend, reducing the risk of solids buildup and blockage in waste lines carrying heavier drainage loads. Plumbers specify long-radius bends in horizontal-to-vertical transitions and in locations where flow characteristics are critical to system performance.

• 45-degree long-radius 1/8 bend for smooth directional changes in cast iron DWV and sewer drain lines
• No-hub end connections for fast, tool-assisted coupling installation with standard no-hub bands
• Meets ASTM 888, CISPI 301, and NSF Certification requirements for cast iron soil pipe fittings
