Anvil 2" Class 300 Malleable Iron Trap

The Anvil 0310539606 is a 2-inch pipe trap built from malleable iron and rated for Class 300 service. It suits plumbers and maintenance teams who need a durable drain component for high-pressure piping systems. The straight, threaded design fits standard Schedule 80 installations in commercial or industrial settings.

Female NPT Threads and 500 psi Rating

Both ends feature 2-inch female NPT threads for direct connection to male-threaded pipe without extra adapters. Malleable iron construction resists mechanical stress and vibration in demanding environments. The fitting handles a maximum operating pressure of 500 psi at 150 degrees Fahrenheit, supporting steam, water, or gas lines.

Upgrade From Lower-Class Fittings

This trap replaces Class 150 or lighter fittings when system pressure or temperature demands a stronger rating. The jump is worth it when design specifications call for Class 300 components to meet code or safety margins. It is not for systems requiring welded joints, larger diameters, or pressure ratings beyond 500 psi.
