The Adaptall Series 9335 Straight Steel Rigid Male Metric x Female ORB adapters are high-quality hydraulic fittings designed to connect metric and ORB (O-Ring Boss) thread systems. The male end features a straight metric thread with a 60° recessed cone, commonly used in European hydraulic systems, while the female end is designed with SAE J1926 ORB threads, which are recognized for their leak-prevention capabilities in medium and high-pressure systems. The ORB connection uses a straight thread and an O-ring that compresses into a chamfer on the female port, creating a secure, leak-free seal. This mechanical connection ensures reliable performance in various hydraulic applications, offering durability and ease of installation with strong sealing properties.
