Adaptor - SAE Flange - CD 61 Split Clamp

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.
