90-Degree Angled Male ORB (O-Ring Boss) adapters are high-performance fittings commonly used in hydraulic systems to provide secure, leak-free connections. These adapters feature a straight thread design, with a male ORB connection that includes an O-ring for sealing. The female port has a straight thread and a machined surface to create a smooth, flat area (minimum spot-face) along with a chamfer where the O-ring seats. When the male connection is tightened, the O-ring is compressed into the chamfer, forming a leak-tight seal. This connection style is recommended by the NFPA (National Fluid Power Association) for its ability to prevent leaks, making it ideal for high-pressure fluid power systems. The SAE J1926 standard for ORB ports ensures reliable, mechanical connections, offering long-lasting durability and excellent sealing performance in demanding industrial applications.
