ORB Plug Adapters are precision fittings designed for leak-free sealing in hydraulic systems. These adapters feature Straight Thread O-Ring Boss connections, often referred to as SAE J1926 or ORB ports. The male connector has a straight thread with an integrated O-ring, while the female port has a straight thread and a machined surface with a chamfer where the O-ring is seated. When the male and female connections are tightened, the O-ring compresses into the chamfer, creating a secure, mechanical seal that effectively prevents leaks. This sealing method is recommended by the National Fluid Power Association (NFPA) for its reliability and is ideal for high-pressure fluid systems, ensuring optimal performance and durability in industrial applications.
