The Series 6818 45-Degree Angled Male Adjustable ORB x Female ORB adapters, made from durable carbon steel, are designed for high-performance fluid systems requiring leak-free connections. These adapters feature a male SAE J1926 Straight Thread O-Ring Boss (ORB) connection, which includes a straight thread and an O-ring. The female ORB port has a straight thread with a smooth, flat surface and a chamfer where the O-ring seats, forming a secure seal when the O-ring is compressed into the chamfer. This mechanical connection style, recommended by the National Fire Protection Association (NFPA) for medium and high-pressure hydraulic systems, ensures reliable, leak-resistant performance. The adjustable male ORB design provides flexibility during installation, making these adapters ideal for systems that demand high-quality, durable connections.
