Merit Brass 125 lb lead free fitting 3" square head solid plug NPT female red brass fittings are designed for low pressure applications involving water, oil, and gas (W.O.G.). These fittings have pressure ratings of 125 psi for steam and 200 psi for W.O.G., and they comply with ANSI B 1.20.1 and ANSI B 16.15 standards. Their construction provides superior corrosion resistance compared to yellow brass, while the material's relative softness facilitates easy installation and ensures a tight seal. Brass fittings are predominantly employed for water in commercial plumbing and OEM applications, but they are also suitable for use in oil, gas, and steam systems.
