How does this compare to brass air fittings? A: Steel construction offers superior durability and corrosion resistance compared to brass alternatives, especially in high-temperature environments up to 250 degrees F where brass fittings may soften or fail. The case-hardened steel also withstands impact damage and repeated connections better than softer brass materials in demanding workshop conditions.
