Frequently Asked Questions

What is the difference between Class 3000 and Class 6000 fittings?

The class indicates the pressure rating and wall thickness of the forged fitting. Class 3000 pairs with standard schedule pipe (Sch 40/XS), while Class 6000 suits heavier schedule 80/XXS systems. Match the fitting class to your pipe schedule and design pressure.
