Adaptor - SAE Flange - 90° Elbow

A SAE Flange – 90° Elbow Adaptor is a hydraulic fitting designed to connect two flanged components at a right angle, typically used in high-pressure systems where space constraints or directional changes are required.

SAE Flange – 90° Elbow Adaptor Overview

Standards

• SAE J518: Covers both Code 61 (standard pressure) and Code 62 (high pressure) flanges.
• ISO 6162-1/2: International equivalents for Code 61 and Code 62.

Design & Configuration

• Angle: 90° elbow for sharp directional changes in hydraulic lines.
• Ends: Typically two flanged ends (Code 61 or Code 62), but can also be mixed with other types like JIC or NPT.
• Mounting: Requires O-rings and split flange clamps for sealing and securing.

Materials

• Carbon steel with trivalent zinc plating – standard for industrial use
• 316 stainless steel – for corrosive or marine environments
• Forged construction – for strength and durability

Code 62 versions are available for pressures up to 6,000 psi.

Applications

• Hydraulic systems in:
  • Construction and mining equipment
  • Agricultural machinery
  • Industrial fluid power systems
• Ideal for tight spaces and directional routing

Installation Tips

• Use the correct O-ring and split flange clamp.
• Ensure flange faces are clean and aligned.
• Tighten bolts evenly in a cross pattern to avoid leaks or flange distortion.
