Anvil Drain Coupling 1/2 Inch NPT

This Anvil drain coupling is a galvanised steel pipe fitting designed for plumbing installations that require a 1/2 inch NPT connection. It meets API Specification 5L and is rated for a maximum working pressure of 300 psi WOG. The component is supplied new and suits professional and DIY pipework.

Sustained Pressure Performance 300 psi

Under continuous system pressure the galvanised steel body maintains its seal up to the rated 300 psi WOG without deformation. The NPT threads resist loosening during prolonged thermal cycling and vibration. Installations needing higher pressure ratings or different pipe diameters will require alternative fittings.
