Msi Products Inc A293083216 Reducing Coupling 300lb 2x1

Product Description

The MSI PRODUCTS INC A293083216 is a 300-lb black malleable iron reducing coupling designed to join two sections of threaded pipe of different diameters in a straight-line transition. It steps pipe runs up or down without requiring additional fittings, keeping installations compact and reducing potential leak points. Rated for 350 to 600 psi service, it is built for higher-pressure piping systems. The fitting conforms to ASME B16.3 dimensional standards, ASTM A197 material specifications, and ASME B1.20.1 threading standards. Full lot traceability is maintained, with material test reports available upon request to support quality assurance and compliance documentation. Manufactured in an ISO-certified facility and pressure tested for consistent performance.

This reducing coupling is used in commercial and industrial piping applications where a threaded pipe run must transition between two different nominal pipe sizes. Typical installations include gas distribution, steam, and compressed-air systems where higher-pressure malleable iron fittings are required. Plumbers, pipefitters, and mechanical contractors use these fittings when building or modifying threaded iron pipe systems in both new construction and retrofit work. The black finish and 300-lb pressure class make this coupling well suited for above-ground and in-wall applications that demand durable, code-compliant components.

Key Features

• Reduces 2-inch pipe to 1-inch pipe in a single straight fitting with no additional hardware
• Rated 350 to 600 psi for use in higher-pressure piping systems
• Malleable iron construction with black finish provides durability and corrosion resistance
• Conforms to ASME B16.3 dimensions and ASTM A197 material specifications
• Threaded per ASME B1.20.1 for consistent, leak-resistant connections
• Full lot traceability with material test reports available upon request
• Manufactured in an ISO-certified, pressure-tested production facility

Compatibility

Designed as an OEM-style replacement and new-installation fitting for 300-lb class threaded malleable iron piping systems requiring a 2-inch to 1-inch reducing transition.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes, including ASME B31 piping standards and local mechanical or plumbing codes. Shut off and depressurize the piping system completely before removing any existing fittings or threading new connections. Apply an appropriate pipe thread sealant or PTFE tape to the male threads before assembly and tighten to the fitting manufacturer's recommended engagement depth. Do not use pipe wrenches on the body of the fitting in a way that could crack the casting.
