Constructed from brass, this reusable fitting is designed for use in hydraulic fluid connector assemblies where reliable, field-serviceable connections are required. As part of the Aeroquip Reusable Fittings line, the 4213-12-12B is a cap-style fitting suited to hydraulic line termination and port sealing applications across industrial fluid systems.
Brass construction offers good corrosion resistance and compatibility with a range of hydraulic fluids, refer to Eaton's fluid compatibility documentation for detailed guidance. The reusable design allows the fitting to be disassembled and reinstalled, reducing replacement costs in maintenance-intensive environments.
So, this is brass, right? Will that hold up okay with different hydraulic fluids or will it corrode?
