The ASC Engineered Solutions 8700158754 is a 1-inch female pipe thread (FPT) standard merchant galvanized coupling used to join two straight sections of pipe in low-pressure service lines. Constructed from galvanized steel, this coupling provides corrosion resistance suited for water, oil, air, and gas distribution systems. The merchant-pattern design offers a shorter end-to-end length compared to full-pattern couplings, making it a practical choice for tight-space installations. Licensed plumbers and pipefitters typically install this fitting in residential and light commercial mechanical systems where threaded iron or steel pipe is specified.
This coupling is commonly found in water supply, compressed air, fuel oil, and natural gas distribution lines operating at low pressure. The 1-inch FPT thread pattern on both ends accommodates standard NPT male-threaded pipe or fittings. It is well suited for maintenance repairs, new rough-in work, and retrofit piping runs where a straight inline connection is needed between two threaded pipe segments.
Designed as an OEM-style threaded fitting for use with standard 1-inch NPT steel or iron pipe in low-pressure residential and commercial piping systems.
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 supply line completely before disassembling or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the male NPT threads before assembly. Do not over-tighten threaded connections, as this can crack fittings or damage threads.
