Product Selection Differences for Malleable Iron Fittings

When selecting Malleable Iron Fittings, there are several key differences to consider:

1. Material: Malleable iron fittings are typically made from white iron or black iron. White iron fittings are more corrosion resistant and are suitable for potable water applications, while black iron fittings are more commonly used for gas applications.

2. Coating: Some malleable iron fittings are coated with a protective layer such as zinc or black oxide to enhance corrosion resistance. The type of coating can impact the durability and longevity of the fitting.

3. Pressure Rating: Malleable iron fittings come in different pressure ratings, such as Class 150, Class 300, and Class 600. The pressure rating determines the maximum pressure the fitting can handle, so it's essential to select the appropriate rating based on the intended application.

4. Thread Type: Malleable iron fittings come with either tapered (NPT) or parallel (NPS) threads. It is crucial to match the fitting's thread type with the corresponding pipe threads to ensure a proper seal and prevent leaks.

5. Sizes and Configurations: Malleable iron fittings are available in various sizes and configurations to accommodate different piping needs. Consider the required size, angle, and connection type when selecting fittings for your specific application.

6. Standards Compliance: Ensure that the malleable iron fittings you choose comply with industry standards such as ASME, ASTM, and ANSI to guarantee quality and performance.

7. Manufacturer Reputation: Consider the reputation of the manufacturer when selecting malleable iron fittings. Look for reputable companies known for producing high-quality and reliable fittings.

By considering these key differences, you can make an informed decision when selecting malleable iron fittings for your specific requirements.
