AORFS Plugs -with male ORFS thread

The following category includes a group of plugs with male ORFS threads designed for plugging female ORFS threads, e.g. K41 hydraulic hose fittings ( ORFS ) Plugs come as a set with ORFS sealing O-ring. Execution : zinc-plated free-cutting steel. The plugs are also excellent as ORFS thread gauges : they allow for quick identification of ORFS threads. We also offer plugs with female ORFS thread.

What is an AORFS plug ?

An AORFS plug is a reliable sealing element used in hydraulic systems, which allows for effective closing of unused openings in hydraulic circuits. Thanks to precise manufacturing from high-quality materials, the AORFS plug ensures excellent tightness and long-term protection against leaks and contaminants. The AORFS plug is characterized by a solid construction made of high-grade steel, which guarantees resistance to high operating pressures and difficult operating conditions. The applied anti-corrosion coating protects the product against moisture and chemical substances, extending its lifespan. The thread, made according to hydraulic standards, ensures a precise fit to system components, eliminating the risk of leaks. Application of the AORFS external plug : The AORFS plug is widely used in power hydraulic systems, where it acts as a protection against leaks of operating fluids and the ingress of contaminants into the system. It is an ideal solution for temporary or permanent plugging of holes in hydraulic lines. 

AORFS plugs for ORFS hydraulic fittings

AORFS plugs are used to close and secure ORFS standard connections used in power hydraulic systems. They allow for plugging an unused port or system termination, protecting the open connection and enabling proper circuit closure. They are used during construction, modernization, servicing, and protection of hydraulic systems.

The ORFS (O-Ring Face Seal) standard utilizes a face seal with an O-ring. For this reason, when selecting an AORFS plug, attention should be paid not only to the thread size but also to the element's compatibility with the ORFS connection geometry.

What are AORFS plugs used for?

An AORFS plug allows for closing the appropriate ORFS connection without having to rebuild the rest of the system. It can be used, among others, at unused connection points and during service work and hydraulic system modifications.

A properly selected plug is particularly useful where the system has an additional connection that is not used in a given machine configuration.

ORFS face seal used in hydraulics

ORFS, or O-Ring Face Seal, is a connection system using a seal on the face surface. A characteristic element of this standard is the O-ring working with the appropriately shaped surface of the other part of the connection.

One should not select a plug solely based on a similar thread diameter. In hydraulics, there are, among others, ORFS, JIC UNF, BSP, NPT standards and metric connections, which may look similar but are not interchangeable.

How to choose the right AORFS plug?

Before purchasing, the connection to be closed must be accurately identified. In the case of AORFS plugs, it is crucial to confirm the ORFS standard and select the correct size.

• identify the connection standard as ORFS,
• check the thread size,
• verify the surface and sealing method,
• match the plug to the correct connection type,
• check the technical parameters of the specific variant,
• inspect the condition of the sealing surfaces before installation.

Plugs and caps for hydraulic systems

Different types of connections can occur within a single hydraulic system, so the AORFS plug should only be used in the place intended for the appropriate ORFS standard. Attempting to use a plug of a similar diameter but made in a different standard can lead to incorrect fitting of components.

If there are also other types of connections in the system, check hydraulic plugs and caps and other hydraulic fittings available at HYDRON.

FAQ - AORFS plugs

What does AORFS mean?

The designation refers to the design of a plug intended for the appropriate connection in the ORFS system. When purchasing, check the exact size required for a given system.

What is an AORFS plug used for?

The plug is used to close the appropriate ORFS connection, for example, an unused point in a hydraulic system.

Are ORFS and JIC compatible with each other?

No. ORFS uses a face seal with an O-ring, while JIC uses 37° conical surfaces. These are different connection systems.

How to choose the ORFS plug size?

Identify the connection standard and its size, and then compare them with the parameters of the specific AORFS plug.
