ORFS Cap / Plug 9/16" internal thread

The ORFS 9/16" cap / plug with internal thread is a hydraulic component designed for plugging hydraulic hose ends equipped with a compatible CAT (AORFS) external thread. The product consists of an internal thread nut and a special cone located inside the nut. This design allows for closing a properly matched hydraulic hose end.

The plug is made of galvanized free-cutting steel. It has an ORFS 9/16" internal thread, with the dimension measured by a caliper inside the nut ranging from 12,7 to 13,0 mm. The cap is intended for closing appropriate CAT (AORFS) ends used on hydraulic hoses.

Technical parameters of the ORFS 9/16" cap

Product type: hydraulic cap, ORFS plug.
Thread size: 9/16".
Thread type: internal ORFS.
Caliper thread measurement inside the nut: 12,7–13,0 mm.
Design: nut with internal thread and a special cone placed inside the nut.
Material: free-cutting steel.
Surface protection: zinc plating.
Purpose: plugging CAT (AORFS) external threads on hydraulic hoses.

Application of the ORFS 9/16" plug in power hydraulics

The ORFS 9/16" cap is used for closing compatible hydraulic hose ends equipped with a CAT (AORFS) external thread. It can be used when disconnecting hoses, replacing components, maintenance work, and securing hydraulic installation ends.

A properly selected cap helps limit the ingress of contaminants into the disconnected hose and the outflow of oil residues during work on a depressurized system. Before use, verify the thread size and the design of the mating elements.

ORFS 9/16" internal thread – size identification

The plug has an ORFS internal thread in 9/16" size. An additional identification parameter is the thread measurement inside the nut, which is 12,7–13,0 mm when measured with a caliper.

The indicated range can help in identifying the correct cap variant. However, when selecting, you should also check the hose end type, as the thread measurement alone does not confirm full compatibility of the hydraulic connection elements.

ORFS cap design – nut and special cone

The cap consists of a nut equipped with an internal thread and a special cone placed inside the nut. Both elements form a complete plug intended for closing compatible hydraulic hose ends with an external thread.

When selecting, consider the thread compatibility and the fit of the conical element to the hose end design. Correct matching of the mating surfaces is important for effective closure of the connection.

Galvanized free-cutting steel

The ORFS 9/16" cap is made of galvanized free-cutting steel. The zinc coating provides protection of the steel surface against corrosion.

When choosing a plug, consider the requirements of the hydraulic installation, including the operating environment and material compatibility of the mating elements.

Plugging CAT (AORFS) ends on hydraulic hoses

The ORFS 9/16" plug with internal thread is intended for closing properly matched CAT (AORFS) ends equipped with an external thread. The product can be used during service work and for securing hydraulic hose ends that require plugging.

This variant should be distinguished from plugs with an external thread, intended for closing compatible ends with an internal thread. Choosing the right product depends on the type and design of the hose end.

Selecting the ORFS 9/16" cap for a hydraulic hose

Before purchasing, check the external thread size of the hydraulic hose end and its design. This variant has an ORFS 9/16" internal thread and is intended for compatible CAT (AORFS) ends.

A helpful identification parameter is the thread measurement inside the nut, which is 12,7–13,0 mm. You should also consider the fit of the internal cone and the condition of the mating surfaces. The thread size alone should not be the sole basis for selecting a cap.

Assembly and inspection of the ORFS 9/16" plug

Before starting assembly, turn off the device and safely depressurize the hydraulic system. Then clean the hose end and inspect the condition of the thread, nut, and internal conical element.

The plug should be installed on a compatible CAT (AORFS) end, according to the requirements of the connection system used. After assembly, check the correctness of the fastening and the tightness of the closure. If the cap is to operate in a pressurized installation, it is necessary to confirm the allowable parameters of the complete connection.
