Why use brass fitting on gas cylinders instead of steel fittings?

Brass fittings are preferred for gas cylinders because brass has good corrosion resistance, which helps prevent leaks and maintains the integrity of the gas cylinder. Brass fittings are also easier to tighten by hand compared to steel fittings, making them more user-friendly for installation and removal. Additionally, brass fittings are less likely to seize over time, facilitating maintenance and replacement if necessary.
