Value Collection 410S03 Black Iron Coupling 3/8 in Threaded

Product Description

The VALUE COLLECTION 410S03 is a straight threaded coupling for 3/8-inch NPS pipe, manufactured from malleable iron with a black finish. Rated Class 150 and conforming to ASTM standards, this fitting connects two lengths of pipe in a straight run and handles liquid and gas service up to 300 psi. The threaded end connections accept standard NPS fittings on both sides. Plumbers, pipefitters, and mechanical contractors use this coupling in low-pressure gas lines, water supply systems, and general-purpose piping applications where a durable iron fitting is required.

This coupling is suited for residential and light commercial piping installations. It is a standard straight fitting used wherever two threaded pipe segments must be joined without a change in direction or diameter. Typical applications include natural gas distribution piping, steam systems, compressed air lines, and water supply runs. The black finish distinguishes it from galvanized fittings and is standard practice for gas piping in many jurisdictions.

Key Features

• Malleable iron construction rated for 300 psi liquid and gas pressure service
• Class 150 classification per ASTM standards
• NPS threaded end connections on both ends for standard pipe compatibility
• Straight coupling profile for in-line pipe joins without direction change
• Black finish suitable for gas piping installations per common code requirements

Compatibility

Designed as an OEM-style replacement and standard-stock fitting for 3/8-inch NPS threaded malleable iron pipe systems rated at Class 150.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the IPC or IFGC. Shut off and depressurize the pipe system completely before removing or installing any fitting. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly, and tighten to a firm engagement without over-torquing the fitting. Pressure-test the system after installation to confirm a leak-free joint before returning it to service.
