What are ORFS 90° fittings?

ORFS 90 (O-Ring Face Seal) fittings are hose fittings designed for operation in hydraulic systems with the highest working pressures. Thanks to the use of a flat seal with an O-ring, this type of fitting provides unparalleled tightness, reliability and durability. ORFS fittings are often referred to as the American type because they are widely used in machines manufactured in the United States, such as John Deere, JCB, Caterpillar and others. ORFS 90 fittings are intended for creating leak-proof connections in hydraulic systems operating under extreme pressures. Right-angle changes in the direction of the medium flow, which is crucial in installations requiring optimal hose routing in limited spaces. Designed to work in the most demanding conditions, with working pressures reaching 6000 PSI.

Where are ORFS 90 fittings used?

ORFS 90 fittings are used in installations requiring the highest tightness and load resistance, such as: Machines manufactured in the USA: Typical for hydraulic systems in machines of brands such as John Deere, Caterpillar, JCB, Case, which makes them a standard in the construction, agricultural and mining industries. Hydraulic and power industry: Construction, mining and industrial machinery. Transport and automotive: Power steering systems and hydraulic brakes. Agriculture: Tractors, combines and other agricultural machinery. Energy and heavy industry: High-pressure transmission systems.
