Adaptor - SAE Flange - 45° Elbow

A SAE Flange – 45° Elbow Adaptor is a hydraulic fitting designed to connect two components at a 45-degree angle using SAE J518 flange connections. These adaptors are commonly used in high-pressure hydraulic systems where space constraints or routing requirements necessitate an angled connection.

SAE Flange – 45° 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 respectively.

Design & Configuration

• Angle: 45° elbow for directional changes in hydraulic lines.
• Ends: Typically two flanged ends (either Code 61 or Code 62), but can also be mixed with other types like NPT, JIC, or ORFS.
• Mounting: Requires O-rings and split flange clamps for secure sealing.

Materials

• Carbon steel (zinc-plated) – standard for industrial use
• 316 stainless steel – for corrosive or marine environments
• Forged construction – for strength and durability

Applications

• Hydraulic systems in:
  • Construction and mining equipment
  • Agricultural machinery
  • Industrial fluid power systems
• Used where space constraints or routing angles require a 45° connection

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.
