Charlotte Pipe nh-4 Cast Iron 90 Degree No-hub Bend 4 Inches X 4 Inches

Product Description

The Charlotte Pipe nh-4 is a 4 inch by 4 inch cast iron 90 degree no-hub bend designed for use in drain, waste, and vent systems. This fitting is built for sanitary and storm drain applications where durability and long-term performance are required. Cast iron has been the standard material for DWV piping for hundreds of years, and this bend continues that tradition with a reliable, heavy-duty construction suited for both residential and commercial projects. The no-hub connection type on both ends makes installation straightforward. A no-hub coupling and clamp are used to secure the fitting to the adjoining pipe, eliminating the need for hub-and-spigot or threaded connections. This simplifies rough-in work and speeds up installations for professional plumbers working on new construction or renovation jobs. The nh-4 is rated for temperatures up to 212 degrees Fahrenheit, making it appropriate for standard sanitary drain systems. Cast iron offers a level of crush strength and physical durability that plastic alternatives cannot match. It performs well in high-traffic areas, under concrete slabs, and in multi-story buildings where pipe deflection or impact resistance matters. One of the most recognized advantages of cast iron DWV pipe and fittings is sound attenuation. Cast iron significantly reduces the noise of draining water compared to PVC or ABS systems, which is an important consideration in hotels, apartment buildings, offices, and healthcare facilities. The gray color is standard for cast iron no-hub fittings and is consistent with Charlotte Pipe product lines used in commercial plumbing. Charlotte Pipe is a well-known manufacturer in the plumbing trade, producing cast iron soil pipe and fittings that meet industry standards for drainage systems. The nh-4 90 degree bend is a core fitting type used wherever a plumbing run needs to change direction by 90 degrees, such as transitioning from a vertical stack to a horizontal drain line.
