The ASC Engineered Solutions 8700158556 is a standard merchant galvanized steel coupling designed to connect two straight pipe segments using female pipe thread (FPT) connections on both ends. At 1/4 inch on each port, this fitting is suited for low-pressure piping systems carrying water, oil, air, or gas. The galvanized steel construction provides corrosion resistance for general-purpose plumbing and mechanical applications. Plumbers, pipefitters, and mechanical contractors install this type of coupling where a reliable, code-compliant inline connection is required without directional change.
This coupling is commonly used in residential and light commercial piping installations. Typical applications include potable water distribution, compressed air lines, fuel oil supply lines, and low-pressure gas piping. Its standard merchant profile means it conforms to widely accepted dimensional standards, making it straightforward to source and install as a direct replacement or new-construction fitting in a variety of pipe assemblies.
Designed as a standard-thread galvanized steel coupling for use with 1/4 inch female pipe thread connections in low-pressure water, oil, air, and gas 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) or International Fuel Gas Code (IFGC) where relevant. Shut off supply pressure and depressurize the line before removing or installing any fitting. Apply appropriate thread sealant or PTFE tape to male threads before engagement. Do not overtighten, as this can crack fittings or distort threads.
