The ASC Engineered Solutions 8700158150 is a 1-inch malleable black iron standard merchant coupling designed for straight pipe-to-pipe connections in low-pressure piping systems. This fitting joins two sections of straight pipe along a common centerline and is suited for use in water, oil, compressed air, and gas distribution lines. The malleable iron construction provides reliable mechanical strength for general-purpose piping work. Licensed plumbers and pipefitters typically install this fitting during new construction, retrofit, or maintenance of low-pressure service lines.
This merchant coupling is applied in residential and light commercial plumbing, HVAC condensate and process piping, and industrial utility lines where low-pressure service conditions are present. Its standard 1-inch thread size makes it a common choice across a wide range of pipe assemblies involving black iron or compatible steel pipe. It is sold individually and is appropriate for any trade application requiring a straightforward inline pipe coupling at this pipe size.
Designed as an OEM-style replacement or new-installation fitting for standard 1-inch NPT black iron or steel pipe systems used in low-pressure plumbing, HVAC, and utility piping applications.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off and depressurize the line before disassembling or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly. Do not overtighten — hand-tighten and then use a pipe wrench for final make-up to avoid cracking the fitting.
