ORFS 45 (K45) CATERPILLAR Fittings

ORFS hose fittings at a 45-degree angle. 

ORFS 45-degree fittings are fittings designed for crimping onto hydraulic hoses with a flat seal and ORFS thread, also known as American thread. The ORFS fitting group consists of elements designed to transfer the highest pressures - the seal is achieved by screwing the flat-face fitting with a male threaded flat-face fitting ( AORFS ) and a special seal ( ORFS O-ring ) Presented below are 45-degree elbow fittings ( obtuse angle ); our offer also includes ORFS 90 elbow fittings at a 90-degree angle ( K42 ), ORFS straight fittings ( K41 ) and the previously mentioned male threaded fittings K21 AORFS. In our offer, you will also find connectors with ORFS threads. The fittings are suitable for hoses with one, two, or four steel braids. ORFS45 fittings are an excellent solution for hydraulic systems requiring reliable connections at a 45° angle. Due to their popularity in machinery brands such as John Deere, Caterpillar, or JCB, they are synonymous with durability, leak-tightness, and the highest quality. Choose ORFS45 fittings to ensure your installation's reliable operation even in the most demanding conditions.

What are ORFS45 fittings?

ORFS45 (O-Ring Face Seal) fittings are hydraulic components designed specifically for applications requiring a change in the medium flow direction at a 45° angle. Thanks to the flat O-ring seal, they guarantee excellent leak-tightness and high durability in high-load hydraulic systems. Popular in the American market, they are a standard solution in machines such as John Deere, Caterpillar, or JCB. ORFS45 fittings are intended for: crimping hydraulic hoses in high-pressure systems where a change of flow direction at a 45° angle is required. Ensuring maximum leak-tightness, eliminating the risk of leaks even in the most demanding conditions. Operating in dynamic environments with vibrations and variable loads, thanks to their solid construction and precise sealing.

Where are ORFS45 fittings used?

ORFS45 fittings are widely used in many industrial sectors, including: Agricultural and construction machinery: Popular in the hydraulic systems of equipment from American manufacturers such as John Deere, JCB, Caterpillar. Heavy industry: Hydraulic systems requiring reliable angled connections. Transport and logistics: High-pressure power steering and braking systems. Energy: Transmission installations and devices requiring the highest leak-tightness.

Why is it worth choosing ORFS45 fittings?

Ideal for 45° operation: They allow for routing lines in hard-to-reach spaces. Flat O-ring seal: Guarantees maximum leak-tightness, eliminating the possibility of leaks. For extreme pressures: Adapted for operation in high-pressure systems with working pressures up to 6000 PSI. American type: The standard choice in machines manufactured in the United States.
