ORFS hydraulic fittings are also called o-ring face seal fittings or o-ring flat seal fittings. Due to its durability, it is the most popular and reliable choice in international hydraulic fittings. There is nothing like an O-ring face seal fitting or (ORFS) when connecting various hydraulic hoses. Its elastic sealing characteristics make it the best choice for 100% leak-free connections. The design of this fitting is such that when the connection is tightened, this O-ring face seal compresses onto the face sleeve brazed to the end of the tube. This is what makes the seal perfect. The metal-to-metal seal eliminates the possibility of twisting by providing firm support during installation.

ORFS Fitting Sealing Mechanism

The combination of both external and internal sealing mechanisms in ORFS fittings ensures a highly reliable, leak-proof connection. The external O-ring creates a secure seal against environmental leakage, while the internal sealing ensures that the hydraulic fluid remains contained within the system. This dual-seal approach makes ORFS fittings an excellent choice for applications requiring high-pressure resilience, vibration resistance, and long-term reliability.

External Seal Mechanism

The external sealing mechanism of ORFS fittings is achieved through the use of an O-ring positioned on the face of the fitting. When the fitting is tightened, the O-ring makes direct contact with the flat surface of the mating part, creating a highly effective external seal. This ensures that the connection is leak-proof and capable of withstanding high pressures. The flat-face design of the ORFS fitting promotes uniform sealing pressure, which prevents deformation and ensures long-lasting sealing performance. This external seal is particularly beneficial for preventing external fluid leakage in hydraulic systems under dynamic pressures.

Key Advantages of the External Seal:

Prevents fluid leakage from the outside of the fitting.

Offers resistance to high pressures and extreme environmental conditions.

Provides a robust, durable seal for long-term operation.

Internal Seal Mechanism

The internal seal of ORFS fittings is facilitated by the metal-to-metal contact between the fitting’s face and the corresponding mating part. The O-ring in the ORFS fitting serves primarily to create an internal pressure barrier, ensuring that the hydraulic fluid remains confined within the system. The precise flat-face design eliminates the need for additional sealing components, reducing the chances of internal leakage. The O-ring is compressed against the metal face during assembly, forming a tight internal seal that can withstand pressure spikes and vibration. This internal seal is crucial for maintaining system integrity and preventing fluid loss inside the hydraulic circuit.

Key Advantages of the Internal Seal:

Provides a pressure-tight internal connection.

Reduces the risk of internal fluid loss or contamination.

Ensures effective sealing even under high vibration and pressure conditions.
