SAE Split Flanges are one of the most common types of flanges and are designed to meet the SAE J518 standard.
Due to their ability to withstand high pressures, SAE Split Flanges are often used in hydraulic systems for hydraulic connections.

What Are SAE Split Flanges?
SAE Split Flanges are static face seals that use high durometer O-rings as the seals and bolts to hold the force.The O-ring seal compresses between the bottom of the groove in the flange head adapter and the flat surface of the port to provide a perfect, reliable seal. It is available in tapped, uncut and metric threaded hole versions to provide variable system mounting methods.
SAE Split Flange Types
These flanges are also known by other names, such as Code 61 split flanges and Code 62 split flanges. They come in two main pressure ranges: 3000 PSI and 6000 PSI, ensuring compatibility with different hydraulic systems. SAE Split Flanges are manufactured using materials like SS304, SS316L stainless steel, and 20# and 45# carbon steel, offering options for various environmental conditions.

Sizing and Classification
SAE Split Flanges are available in a range of sizes, typically from 1/2″ to 5″, and in some cases, 1/2″ to 3″, depending on the pressure rating. They are classified into four main types based on their profile:
- Split (cut)

- Integral type (uncut)

3.Metric threaded (hole type)

4.Plate type (flat type)

In conclusion, SAE Split Flanges are indispensable components in hydraulic systems. Their ability to create reliable seals under high pressure, coupled with their versatility in mounting methods, makes them a go-to choice for engineers and technicians in various industries.
