SAE Flange | Code 61Flange | Code 62 flanges

SAE flange is considered to be one of the most safety and leak free connection between pipes, tubes or hoses. SAE Flanges are known as code 61 flanges or code 62 flanges according to the working pressure rate.

Main types of SAE flanges

Our product group of hydraulic SAE flanges including the below main types.

Production standard of SAE flanges

Our SAE flanges are designed and produced according to below standards:

  • SAE J 518 C
  • ISO 6162-1: for SAE 3000 psi hydraulic flanges
  • ISO 6162-2: for 6000 psi SAE flanges

Other standards or specifications on customers’ request.

Main series of hydraulic SAE flanges

The above mentioned types of SAE Flanges come in below two series:

  • 3000 psi series / SAE code 61 flanges:

Flange of this series is designed according to ISO 6162 part 1, it is the standard pressure series, someone also call it light duty series, which is mostly known as code 61 flange. Code 61 series flanges are designed for normal pressure applications.

  • 6000 psi series/ SAE code 62 flanges:

Flange of this series is designed according to ISO 6162 part 2, it is known as the high pressure series, someone also call it heavy duty series, which is mostly known as code 62 flange. Code 62 series flange is designed for high pressure applications.

Sizes of hydraulic SAE flange

  • for 3000 psi series SAE hydraulic flanges(code 61 / CD 61 flanges), our size range: 1/2″ to 5″
  • for 6000 psi series SAE hydraulic flanges(code 62 / CD 62 flanges), our size range: 1/2″ to 3″

Materials of Younglee’s SAE flanges

SAE Code 61 flanges and code 62 flanges are usually produce from materials as below:

  • Carbon steel:
  • Stainless steel: 304, 316, 316Ti or corresponding EN/DIN grades 1.4301, 1.4401, 1.4571.

Other steel grades available on customer’s requests.

Surface of ISO 6162 hydraulic flanges

SAE J518C / ISO 6162 flanges made of carbon steel are usually available with below surface treatment.

  • Galvanized (zinc plate), white silver surface
  • Phosphate black surface
  • Blank surface + Oiled.

For stainless steel SAE flange, it is bright surface.

Advantages of our SAE Flanges

Our ISO 6162 hydraulic flanges have below advantages:

  • Accurate dimensions
  • Competitive Prices
  • High performance of mechanical properties
  • Flexible order quantities

Main Applications

SAE flanges are widely used in hydraulic systems, instrumentation tubing system, measurement tubing systems, and other tubing systems where easy removal and non-welding is required. The application industries of hydraulic SAE flanges include high temperature, high pressure and high anti-corrosive harsh conditions industries as nuclear power, oil, chemical, shipbuilding, offshore, metallurgy, machinery, electricity, and so on.
