What is flat face O-ring?
Flat Face O-Ring Hydraulic Fittings use high durometer flat rubber O-rings to effect a gasket like soft seal. The O-ring nests in a special groove machined in the face of the fitting body.
How do you choose O-ring size?
The size of an O-ring can be determined by measuring the diameters and the width of the cross-section. The measurement you will need to include are the internal diameter (ID), outside diameter (OD), and the cross-section width (CS).
What are flat O-rings called?
Flat O-Rings Flat O-rings, also called lathe cut and square rings, are sealing rings with square or rectangle profiles, called torus shapes, that are used as alternatives to the standard O-Ring shape.
How do you measure for a flat face?
The male fittings have the O-ring in a groove in the flat face. MALE: The measurements for the male are taken from the outside of the threads. FEMALE: For Female fittings, the measurement is taken from the inside of the threads.
What is the difference between JIC and NPT?
JIC hydraulic fittings is used in high pressure system, NPT fittings is used in low-pressure system. NPT pipe threads have always been popular, as leaks can be fixed by simply tightening the fitting. NPT is often used to connect port, hydraulic adapter has a combination from JIC to NPT end fittings.
How tight should an O-ring be?
To provide an effective seal, the O-ring’s inside diameter (I.D.) must be smaller than the piston groove diameter, so that the O-ring is slightly stretched, fitting snugly in the groove. This stretch should be between 1%-5% with 2% as the ideal in most applications. A stretch greater than 5% is not recommended.
How tight should O-rings be?
What is a square cut O-ring?
Square Cut O-Rings are exactly like normal O-Rings, except that their cross-sections are square instead of circular. This design increases their working pressure, and form fit more snugly in some spaces.
How do you install an O-ring hydraulic fitting?
Install O-ring on male thread and make sure the O-ring is not cocked or twisted. Abut O-ring to the base of the thread. Lubricate the O-ring with a light coat of the system’s fluid or suitable lubricant. Install retaining ring over the O-ring (if included) and ensure O-ring is seated inside the retaining ring evenly.
What are O-ring face seal fittings?
O-ring face seal fittings offer zero clearance, resistance to over torque and vibration resistance making it an ideal reusable hydraulic fitting solution across many markets. Seal-Lok tube fittings and adapters come in steel and stainless steel.
What are the specifications of seal Lok O-ring fittings?

What are ORFs fittings?
ORFS (O-Ring Face Seal) fittings are becoming the most popular international fitting type used on global OEM machines due to their high level of sealing and their good vibration resistance. The fittings use the O-ring compression mechanism to seal.
What is O-ring hydraulic fittings?
Flat Face O-Ring Hydraulic Fittings use high durometer flat rubber O-rings to effect a gasket like soft seal. The O-ring nests in a special groove machined in the face of the fitting body.
