Straight UNF / ORFS fittings

Straight threaded reducing connections with American UNF / ORFS threads

Straight threaded connections with reduction threads of type UNF to ORFS. From the connection side, a UNF thread with a gasket; on the other side, a male ORFS thread for connecting a hydraulic hose. Material : galvanized free-cutting steel.  Straight UNF ORFS fittings are connection fasteners in hydraulic systems that allow for secure and tight connection of hoses and hydraulic components. The abbreviation UNF stands for Unified National Fine, referring to a specific fine thread standard, while ORFS stands for O-Ring Face Seal, which means face sealing using an O-ring. Such a connection guarantees high tightness and reliability in demanding applications.

Advantages of UNF connectors – precise American threads

UNF connectors are crucial in hydraulics due to precise threads that ensure an excellent fit and minimize the risk of leaks. Thanks to this, they are ideal for high-performance systems, where reliability and tightness are priorities. Their use covers a wide range of applications, from the machinery industry to advanced hydraulic systems.

Application of straight connections with American UNF/ORFS threads

Straight UNF ORFS fittings are widely used in various hydraulic systems, especially where high tightness and reliable connections are required. They are commonly used in the machinery, agricultural, and construction industries, as well as in power hydraulic systems. Thanks to their design, they are ideal for applications requiring frequent assembly and disassembly, while ensuring durability and safe connections. Due to the threads, this type of connection is primarily used in modern Western-made equipment. 

Why are ORFS connectors so leak-proof?

ORFS connectors feature a face-seal design that provides excellent resistance to leaks even at high operating pressures. The O-ring placed on the face surface guarantees a durable seal, which is key in demanding hydraulic applications. As a result, these connectors are indispensable in systems where maintaining pressure is critical.

How to choose the right straight fitting?

The selection of the right straight fitting depends on several factors, such as hose diameter, material of construction, and system operating conditions. The specifics of the application should also be considered to ensure optimal performance and connection durability. A well-chosen fitting guarantees not only tightness but also the long-term reliability of the entire hydraulic system.
