Brass can accommodate pressures to 3000 psi depending on the design and size of the fitting. However, most brass fitting applications are rated for lower pressures. Brass fitting straights, like steel and stainless steel, are machined from hexagonal bar stock, whereas fitting shapes are typically forged.
Although not one of the most common fittings used in fluid power applications, brass fittings are extremely useful in corrosive environments for both hydraulic and pneumatic hose and tubing applications.
