Plumbing Coupling for 3/4" Pipe
The Anvil 0310080403 is a malleable iron coupling rated Class 150 for Schedule 40 piping systems. It connects two sections of 3/4 inch pipe using female NPT threads on both ends. This component suits residential and commercial drainage installations.
Class 150 Pressure Rating
The fitting withstands 300 psi at 150 degrees F, defining its safe operating envelope for water and compatible fluids. Exceeding this pressure or temperature risks joint failure. Verify your system design stays within these limits before installation.
Thermal and Pressure Performance
Malleable iron construction handles the rated 150 degrees F continuously without deformation. The Class 150 rating ensures reliable sealing at the specified 300 psi working pressure. No additional sealing compounds are referenced in the manufacturer data.

Questions about this item
What does the Class 150 rating mean for daily use?
Class 150 indicates the fitting is rated for up to 300 psi at 150 °F, so it handles typical residential and light-commercial water and air lines within those limits.
How does the FNPT thread affect what I can connect?
Both ends use 3/4" female NPT threads, so you screw male NPT nipples or adapters directly into the coupling without additional sealants beyond standard thread tape or paste.
What clearance do I need to install this malleable iron coupling?
The coupling is a straight 3/4" FNPT-to-FNPT body; allow enough pipe length on each side to engage the threads fully plus room for a pipe wrench on the hexagonal flats.
