Malleable Iron Reducing Fitting

Ensure reliable transitions within your fire protection, sprinkler, standpipe, and industrial fluid conveyance systems using the Malleable Iron Reducing Fitting. This component installs directly into threaded piping networks to accommodate adjustments in pipe diameter while maintaining structural integrity and optimal fluid flow under challenging conditions like thermal expansion and vibration.

To satisfy mandatory life safety and mechanical design codes, these fittings fully conform to ASME B16.3 standards (and ASME B16.39 for unions). Every fitting sized 3/8" (10 DN) and larger undergoes rigorous 100% gas testing at a minimum of 100 PSI (6.9 bar) to verify leak-proof performance in critical safety networks.

• High-Grade Malleable Iron: Crafted from durable iron to deliver superior mechanical strength and long-term reliability in demanding environments.
• Precision Threaded Design: Features clean threads for effortless integration into existing piping networks, reducing installation time and project complexity.
• Corrosion Resistance Options: Available in durable black or galvanized finishes to protect against oxidation across indoor and outdoor installations.
• Versatile Pressure Ratings: Offered in standard Class 150 installations or specialized 300# high-pressure system options.
• Rigorously Tested: 100% gas tested at a minimum of 100 PSI (6.9 bar) on sizes 3/8" and larger for secure, leak-free connections.

Always verify local Authority Having Jurisdiction (AHJ) requirements and cross-reference specific system dimensions against manufacturer data sheets before beginning installation.
