A SAE Flange - Code 61 Split Clamp is a hydraulic component used to secure flanged connections in medium-pressure systems. Here's a detailed overview: What is a Code 61 Split Clamp? Code 61 refers to the SAE J518 standard for standard pressure hydraulic flanges, typically rated up to 5,000 psi depending on size. A split clamp is a two-piece clamp that bolts around a flange head to secure it to a port or another flange. These clamps are used with O-ring face seal (ORFS) style flanges to ensure a leak-free connection. Construction & Materials Material: Usually made from carbon steel (zinc-plated) or stainless steel for corrosion resistance. Design: Two halves with bolt holes that align with the flange port; tightened using SAE Grade 5 or 8 bolts. Applications Hydraulic systems in: Construction and mining equipment Agricultural machinery Industrial fluid power systems Used where vibration resistance, high pressure, and easy maintenance are critical. Installation Tips Always use the correct O-ring and torque spec. Ensure flange faces are clean and aligned before tightening. Use even torque across bolts to prevent leaks or flange warping.
