Msi Products Inc A293081208 Malleable Iron Reducing Coupling

Product Description

The MSI PRODUCTS INC A293081208 is a 300 lb black malleable iron reducing coupling designed to connect two sections of threaded pipe of different diameters in a straight inline transition. Sized at 3/4 inches by 1/2 inches, it handles working pressures from 350 to 600 psi, making it suitable for higher-pressure piping systems. The black finish is standard for natural gas and other non-potable applications. Plumbers and pipefitters install this fitting where a pipe run must step down or step up in diameter without introducing additional intermediate fittings. Full lot traceability is maintained, with material test reports available on request to support quality assurance and compliance documentation.

This reducing coupling is used in residential and commercial piping systems including natural gas distribution, steam, and air lines where a compact, threaded diameter transition is required. It threads directly onto standard NPT pipe ends and is suited for retrofit and new construction installations. The compact body keeps the transition short, minimizing the overall footprint of the fitting assembly in tight mechanical spaces.

Key Features

• 3/4 inches by 1/2 inches reducing configuration for inline diameter transitions
• 300 lb pressure class rated for 350 to 600 psi service
• Malleable iron construction with black finish for strength in higher-pressure applications
• Conforms to ASME B16.3 dimensional standards
• Meets ASTM A197 material specifications
• Threaded to ASME B1.20.1 NPT threading standards for proper fit
• Manufactured in an ISO-certified facility with pressure testing for performance and consistency

Compatibility

Designed as an OEM-style replacement and standard-duty fitting for threaded black iron pipe systems conforming to ASME B16.3 and ASME B1.20.1 NPT threading standards.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and IFGC or IPC requirements for the intended service. Shut off and depressurize the pipe system completely before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape rated for the service medium to all male threads before assembly. Do not over-tighten; use a pipe wrench and a backup wrench to avoid stressing adjacent pipe or fittings.
