Product Selection Differences for Screwed Fittings

When selecting screwed fittings, there are several key differences to consider:

1. Material: Screwed fittings are available in various materials such as brass, stainless steel, and PVC. The material choice depends on factors like the fluid being conveyed, pressure and temperature requirements, and the environment in which the fitting will be used.

2. Size: Screwed fittings come in different sizes to accommodate various pipe diameters. Ensure the fitting size matches the pipe size to prevent leaks or pressure drop.

3. Thread Type: Screwed fittings have either tapered (NPT) or parallel (BSPP) threads. The choice of thread type depends on the application requirements and the pipe system being used.

4. Pressure Rating: Different screwed fittings have varying pressure ratings, so it's essential to select fittings that can handle the required pressure of the system.

5. Corrosion Resistance: Consider the corrosion resistance of the material based on the environment in which the fittings will be installed. This is crucial in ensuring the longevity and reliability of the system.

6. Certifications: Check for certifications like ASTM, ANSI, ISO, or others based on industry standards to ensure the fittings meet quality and safety requirements.

7. Cost: Evaluate the overall cost of the fittings, considering factors like initial purchase price, maintenance costs, and potential downtime due to fittings failure.

By considering these key differences, you can choose the most suitable screwed fittings for your specific application needs.
