Anvil 1/4" NPT Galvanized Coupling

This Anvil coupling connects two sections of 1/4 inch NPT pipe in plumbing and fluid-transfer systems. The galvanized steel body resists corrosion in water, air and oil lines. It meets API Specification 5L for consistent thread quality and pressure containment. The component is supplied new and ready for installation.

Galvanized steel material and NPT threads

Galvanized coating protects the fitting from rust without additional sealants on the threads themselves. NPT taper threads create a mechanical seal when tightened, reducing the chance of leaks in low-pressure circuits. The API 5L marking confirms the fitting was manufactured to a recognised pipe-standard. No gaskets, lubricants or specialised tools are included in the package.

300 psi WOG pressure limit

The fitting is rated for a maximum working pressure of 300 psi water, oil or gas at ambient temperature. Systems that operate above this pressure or that experience severe pressure spikes require a higher-rated component. The 1/4 inch NPT size restricts flow capacity compared with larger pipe diameters. Buyers needing higher pressure ratings or larger bore sizes must select a different fitting.

Questions about this item

Will the galvanized steel threads need re-sealing or replacement after repeated disassembly?

The NPT threads on this galvanized steel coupling are designed for repeated assembly with fresh thread sealant each time; the fitting itself does not wear out under normal use.

What pressure limit applies when the line runs continuously at the rated 300 psi WOG?

The coupling is rated for 300 psi water, oil, or gas non-shock service; sustained operation at that pressure is within its design envelope.

Does the galvanized coating affect heat dissipation or noise when fluid flows through it all day?

The galvanized steel body does not generate noise, and its thermal mass is negligible in a 1/4 in NPT line carrying fluid at normal plumbing temperatures.
