Asc Engineered Solutions 8700158259 Black Iron Coupling

Product Description

The ASC Engineered Solutions 8700158259 is a 1-1/2 inch malleable black iron merchant coupling designed for straight pipe-to-pipe connections in low-pressure piping systems. Built from malleable iron with a black finish, this standard coupling provides a reliable threaded joint in lines carrying water, oil, air, or gas. Plumbers, pipefitters, and mechanical contractors install this fitting where a simple inline connection is needed without directional change. Its malleable iron construction allows it to withstand moderate mechanical stress and vibration better than brittle cast iron, making it a practical choice for service and repair work as well as new installation.

This merchant coupling is suited for residential and light commercial piping applications where low-pressure service conditions apply. Typical uses include water supply lines, compressed air distribution, oil lines, and low-pressure gas piping. The 1-1/2 inch size fits standard NPT threaded pipe of the same nominal diameter. It is sold individually and is a common stock fitting for service vans and supply houses alike.

Key Features

• Malleable black iron construction for improved toughness compared to standard cast iron
• 1-1/2 inch nominal size with standard NPT threads for compatibility with common threaded pipe
• Straight inline coupling design connects pipe section to pipe section without directional change
• Suitable for low-pressure water, oil, air, and gas piping applications
• Sold individually — quantity of one per unit

Compatibility

Designed as an OEM-style replacement and standard-stock fitting for 1-1/2 inch NPT threaded black iron piping systems in low-pressure service applications.

Installation Notes

Installation is typically performed by a licensed plumber or pipefitter following applicable IPC or IFGC code requirements for the service medium. Shut off and depressurize the line completely before removing or installing any threaded fitting. Apply appropriate thread sealant or PTFE tape to NPT threads before assembly, and tighten to a snug, leak-free fit using pipe wrenches — do not overtighten malleable iron fittings. Pressure-test the completed assembly before returning the system to service.
