GALVANIZED UNION (BRASS TO IRON SEAT) UL/FM Listed

Galvanized Malleable Iron Pipe Unions – Class 150

High-Quality Galvanized Malleable Iron Unions for Reliable Pipe Connections

Our Class 150 Galvanized Malleable Iron Pipe Unions deliver a strong, leak-resistant connection for threaded piping systems. These durable fittings allow easy assembly and disassembly — making maintenance, repairs, and system modifications quick and hassle-free without cutting pipes.

Key Features & Benefits:

• Premium Material: Made from high-grade malleable iron with a hot-dip galvanized coating for superior corrosion and rust resistance. Ideal for indoor, outdoor, and moist environments.
• Pressure Rating: Rated for 150 PSI saturated steam and up to 300 PSI WOG (water, oil, gas) at 150°F — perfect for low-to-medium pressure applications.
• Precision Threads: NPT (National Pipe Thread) female x female ends ensure a tight, secure seal on standard pipe.
• Versatile Applications: Commonly used in plumbing, water supply lines, HVAC, compressed air, natural gas, steam, irrigation, and light industrial piping systems. Great for residential, commercial, and agricultural projects.
• Easy Maintenance: The union design features a ground joint or brass-to-iron seat (depending on model), allowing you to disconnect pipes quickly without disturbing the rest of the system.
• Standards Compliant: Manufactured to meet ASME B16.39, ASTM A197, and other industry specifications. Many sizes are UL/FM listed or NSF-compliant where applicable.                                                                                                                                                                                                                                                       These galvanized unions are built to last and outperform standard fittings in demanding conditions.
