3/4 UNF coupling nut for 12 mm seamless tube

What is a 3/4 UNF 12 mm flaring nut?

A flaring nut is a specialized element used in tube connection technology, where the method of flaring the tube end is used. In the presented product, we are dealing with a solution in the 3/4 JIC flaring nutstandard, based on the UNF thread, which is commonly used in power hydraulics and industrial installations requiring high tightness and resistance to vibrations. The model available in the Hydron offer, i.e. 3/4 UNF 12 mm flaring nut, is designed to work with a steel tube with an outer diameter of 12 mm. Thanks to the use of the UNF (Unified National Fine) standard and the JIC 37° system, we obtain a repeatable and reliable connection that is used both in hydraulic systems, as well as in fuel or industrial installations.

Operating principle of a flared connection

The connection using a UNF flaring nut is based on the mechanical deformation of the tube end, i.e., making a so-called 37° flare. In this process, the tube is properly prepared using flaring tools, and then pressed against the conical surface of the fitting by the nut. The 3/4 flaring nut plays a very important role here – it is responsible for the proper pressure and stabilization of the connection. Thanks to this, we obtain high tightness without the need for additional seals, such as o-rings or washers. This solution is particularly valued in power hydraulics, where the reliability of connections has a direct impact on the safety of the entire system.

JIC standard and UNF thread – what does it mean in practice?

In the case of the Hydron product, the 3/4 JIC flaring nut standard is used, which is based on a 37° sealing angle and a UNF thread. UNF thread is characterized by a fine pitch, which allows for precise tightening and better control of the clamping force. For the user, this means greater durability of the connection and resistance to leaks even under variable operating conditions. The UNF flaring nut is widely used in agricultural and construction machinery, hydraulic systems, and in industry where international standards and component compatibility are required.

Construction and matching to 12 mm tubes

The presented flaring nut has been designed to work with a 12 mm diameter tube. In practice, this means that the entire system should be properly selected and also include complementary elements.

In the Hydron offer, you will find compatible components that form a complete connection system:

Only the combination of these elements with a properly performed flaring operation guarantees the tightness and durability of the entire system.

Application of the flaring nut

The 3/4 UNF flaring nut is used wherever rigid pipes are used. It is a solution often chosen by professionals due to its durability and the possibility of multiple assembly and disassembly without losing sealing properties. Most often, the flaring nut is used in power hydraulics, fuel installations, lubrication systems, as well as in the machinery and automotive industries. The 3/4 flaring nut will work well both in services and in the production of new installations.

Common mistakes when selecting a flaring nut

In practice, one of the most common problems is the incorrect matching of the pipe diameter or thread standard. In the case of this product, please remember that the 3/4 UNF flaring nut is intended for a 12 mm tube and should not be used with other diameters without appropriate reductions. The second significant error is an incorrectly made flare. Even the best 3/4 JIC flaring nut will not ensure tightness if the flare surface is damaged or made at the wrong angle. That is why it is so important to use professional tools and maintain precision during assembly.

FAQ

How to choose a flaring nut? The selection should take into account the pipe diameter, thread type and connection standard. In this case, it is a 3/4 UNF flaring nut intended for a 12 mm tube.

How does JIC differ from other systems? The JIC system is based on a 37° cone and a UNF thread, which ensures high tightness and ease of assembly without additional seals.

Does a UNF flaring nut require a gasket? No, the sealing takes place on a metal-metal cone, which is why correctly making the flare is crucial.
