SAE SFL, SFS straight flange fittings 

Fittings straight flange for SAE hoses - SFL 3000 PSI, SFS 6000 PSI 

The offer includes flange (flanged) hydraulic hose crimp fittings in the light SFL or heavy SFS version. We basically distinguish 2 types of flange fittings: depending on the working pressure: SFL 3000 PSI fittings and SFS 6000 PSI fittings.  Depending on the version, the fittings differ fundamentally in the size of the collar (flange). Flange fittings are used primarily in construction machinery. The connection is achieved by bolting the fittings using special split flanges (colloquially called "half-moons"), which are bolted onto the flange fitting. Flanges are available in the 4SP version (long tail) or in the INTERLOCK version with a double lock, as well as in the SUPERCAT version (increased flange height). We also offer original O-rings for flange fittings (square cross-section) and polyurethane O-rings (super durable). This type of fitting is sometimes referred to as hydraulic flanges. 

Classification of flange fittings 

  • flange fittings light series 3000 PSI (SFL)
  • flange fittings heavy series 6000 PSI (SFS)             

What is a flange fitting?

A flange fitting, also called a flanged end, is a special type of hydraulic hose end that allows the hydraulic hose to be connected to other system components using split flanges and mounting bolts. It is a durable and leak-tight solution used in hydraulic systems with high working pressures and large mechanical loads. How does a flange fitting work? A flange fitting connects to another hydraulic system component by matching the flange to its surface and securing them with bolts. The seal, i.e., special flange gaskets between the flanges, ensures leak-tightness, and the solid mechanical connection allows for the transfer of high pressures and dynamic forces. The flange system allows for quick disconnection and reconnection of the installation. They can be used in many industries, from heavy industry to agriculture. 

Where are hydraulic flanges used?

Due to their strength - hydraulic flanges are resistant to very high pressures and dynamic loads, this type of fitting can be found in: Heavy industry: Hydraulic systems mainly in construction machinery, such as excavators, cranes, loaders. Chemical and oil industry: Systems transferring aggressive chemicals or working fluids at high temperatures and pressures. Hydraulic flanges are an excellent choice for any hydraulic system requiring high-strength and leak-tight connections. Choose the appropriate variant from SFL, SFS, or Supercat and enjoy the reliable operation of your hydraulic installation.
