ORFS fittings, short for O-Ring Face Seal, are a popular choice for high-pressure and high-vibration environments due to their superior leak-free performance. The fitting uses an O-ring seated in a groove in the face of the fitting for sealing. When tightened, the O-ring compresses against the flat face of the female fitting to form a tight, reliable seal. The Face Seal Hydraulic Fittings Tower is a vital resource for professionals who regularly work with high-pressure hydraulic systems, providing them with a broad range of ORFS fittings and O-rings to ensure consistent and secure connections.
