CGA-580 Regulator Inlet Nut & 3" Fitting – Brass, 1/4 NPT, For Helium Argon Nitrogen Cylinders

About This Product

If you're hooking up helium, argon, or nitrogen tanks, this CGA-580 nut and 3-inch inlet fitting is exactly what you need.

It's made from high-grade brass with precision threads, so it seals tight and doesn't leak.

The 3-inch length gives you good reach, and the 1/4 NPT threading is standard for most regulators.

Installation is straightforward: just screw it onto your regulator and cylinder, and you're good to go.

Solid, reliable, and built to handle high pressure without failing.

One nut and one fitting per pack.
