Our 45-Degree Male ORB (O-Ring Boss) adapters, designed according to SAE J1926 standards, are highly effective for providing leak-free connections in medium and high-pressure hydraulic systems. The male connection features a straight thread with an O-ring, while the female port has a straight thread and a machined surface that includes a chamfer where the O-ring seats. When the male and female connections are joined, the O-ring is compressed into the chamfer, creating a secure, mechanical seal. This connection style, recommended by the National Fire Protection Association (NFPA), is known for its excellent leak prevention and is commonly used in critical hydraulic systems.
