2" Extra Heavy 300 Malleable Iron Black Coupling Fittings 69418

Features:
• The elbow is made from galvanized steel, which means it has a protective zinc coating. This coating helps prevent rust and corrosion, making it suitable for use in environments where the pipe might be exposed to moisture or corrosive substances.

Threaded Interior: The interior of the coupling shows threading, which allows it to be screwed onto male threads of two separate pipes, thereby joining them. The threads are precision-cut to ensure a tight and secure fit.

Center Stop: There's often a ridge or a center stop inside the coupling to ensure that both pipes being connected are aligned properly and have equal insertion depth on either side.

Markings on the Exterior: The exterior of the coupling often contains various markings. These can include the manufacturer's mark, size specifications, pressure ratings, and material identifiers. For example, "150" might indicate a pressure rating, and "M" could be a manufacturer's initial.

Hexagonal Shape: The coupling often has a hexagonal shape on the outside to accommodate a wrench, making it easier to tighten or loosen when installing or removing.

Galvanized Finish: The grayish, rough surface texture is characteristic of galvanization. This zinc coating is applied to prevent corrosion and extend the life of the coupling, especially in environments where moisture is present.

Size Indication: There may be a number indicating the nominal size of the coupling, which corresponds to the internal diameter of the pipes it is designed to connect

• This is a 3/4” taper per foot. A pipe is visually inspected for roundness of threads and other visual faults as it is removed from the threading machine
