Malleable Iron Coupling Class 300

The Anvil 0310538202 coupling connects two sections of 3/8 inch NPT pipe in systems rated for Schedule 80 service. It suits installers who need a female-threaded joint rated for high-pressure hydraulic or steam lines. Buyers requiring larger diameters or different thread standards must select another fitting.

Female NPT Threaded Ends

Both ends feature 3/8 inch female NPT threads so the coupling joins male-threaded pipe or nipples without adapters. The Class 300 rating supports 2,000 psi at 150 degrees F, allowing use in demanding pressure applications. No gaskets, sealant or additional hardware are included in the package.

Class 300 Malleable Iron Construction

Malleable iron provides ductile strength that resists cracking under vibration or thermal cycling better than cast iron. The material handles the stated pressure and temperature limits for Schedule 80 piping systems. Threaded connections allow disassembly for maintenance or reconfiguration without cutting pipe.

Questions about this item

Will the malleable iron coupling need replacement due to corrosion under normal water supply conditions?

Malleable iron resists mechanical stress well but is not inherently corrosion resistant; in aggressive water or humid environments the coupling may eventually require replacement, while in benign conditions it can last the life of the piping system.

What pressure limit will be reached first if the system runs continuously at the maximum 2,000 psi rating?

The Class 300 rating allows 2,000 psi at 150 °F; sustained operation at that pressure and temperature leaves no safety margin, so the pressure limit is the first constraint encountered.

Does the coupling generate noticeable heat or noise when fluid flows through it at the rated 2,000 psi all day?

As a passive fitting with no moving parts the coupling produces no mechanical noise and negligible heat; any temperature rise comes from the conveyed fluid, not the coupling itself.
