Charlotte Pipe nh-18 No-hub Long Sweep 4 Inch Cast Iron Dwv 1/4 Bend Fitting

Product Description

The Charlotte Pipe NH-18 is a no-hub long sweep 1/4 bend fitting designed for 4-inch diameter drain, waste, and vent systems. It is made from cast iron and built to handle the demands of both sanitary and storm drainage applications. HVAC technicians, plumbers, and contractors rely on cast iron DWV fittings like this one for their durability, noise reduction, and long service life in residential and commercial installations.

The long sweep design gives this 1/4 bend a gradual change in direction, which reduces flow resistance and minimizes the chance of clogs compared to short-turn fittings. This makes it a preferred choice wherever smooth, unobstructed flow is a priority. The no-hub end style allows for quick, secure connections using standard no-hub couplings and band clamps, making installation faster and more straightforward than traditional hub-and-spigot joints.

Cast iron pipe fittings have been a standard in the plumbing industry for generations. They resist fire, dampen sound, and hold up under high-temperature and high-load conditions. This fitting meets multiple industry standards, including ASTM A74, CISPI 301, CSA Certification, and NSF Approval, so it is accepted in code-compliant installations across North America. It is also domestically manufactured, which is important for projects with Buy American requirements.

At approximately 4-13/16 inches tall, 3-7/8 inches wide, and 2 inches deep, this fitting fits standard 4-inch no-hub drain line configurations. It is a reliable, code-compliant component for new construction, renovation, and repair work in residential, commercial, and light industrial plumbing systems.
