Assorted Galvanized Malleable Iron Plumbing Fittings

Assorted Galvanized Malleable Iron Plumbing Fittings

Product Overview

The Assorted Galvanized Malleable Iron Plumbing Fittings collection is a comprehensive inventory of threaded piping components designed for robust and reliable fluid transport. This assortment brings together a wide variety of shapes, sizes, and configurations—ranging from elbows and tees to couplings and unions—all fabricated from high-strength malleable iron and coated with a protective layer of hot-dip galvanized zinc. Whether for residential water supply, industrial gas lines, or structural applications, this diverse range ensures that contractors and engineers can source every necessary connection from a single, reliable provider, streamlining inventory management and ensuring system compatibility.

Key Features and Benefits

• Comprehensive Variety: A one-stop solution offering fittings in all standard shapes (Elbows, Tees, Crosses, Couplings, Unions, Bushings, Plugs) and sizes (1/8" to 4").

• Superior Corrosion Resistance: The hot-dip galvanized coating provides a heavy-duty barrier against rust and oxidation, making these fittings ideal for outdoor use, wet environments, and exposed piping.

• High Mechanical Strength: Malleable iron offers excellent tensile strength and impact resistance, capable of withstanding high pressure (Class 150 and Class 300) and physical stress without cracking.

• Unified Material Quality: All items in the assortment are manufactured from certified malleable iron (ASTM A197 / EN 1562), ensuring consistent mechanical properties and thread compatibility across the entire inventory.

• Versatile Application: Suitable for a broad range of media, including potable water, natural gas, steam, compressed air, and oil.

Assortment Breakdown

The Assorted Galvanized Malleable Iron Fittings typically include the following categories:

By Connection Type:

• Threaded (NPT/BSP): Tapered threads designed for leak-tight seals when used with pipe dope or Teflon tape.

• Left & Right Threaded: Specialized nipples and couplings for tight spaces or rotating pipe assemblies.

By Geometry:

• Elbows (90° & 45°): For changing the direction of the pipe run.

• Tees (Equal & Reducing): For creating branch lines from a main run.

• Couplings & Unions: For connecting two pipes in a straight line (Unions allow for easy disassembly).

• Bushings & Nipples: For connecting pipes of different sizes or lengths.

• Plugs & Caps: For sealing the ends of pipes.

• Crosses: For four-way distribution networks.

By Pressure Class:

• Class 150: Standard weight for general plumbing and water distribution.

• Class 300: Heavy weight for high-pressure steam and industrial applications.
