Ø38 intermediate sleeve for flaring hydraulic pipes – 38 mm

The Ø38 intermediate sleeve for flaring is a connection element designed for steel hydraulic pipes with an outer diameter of 38 mm. It is used when making pipe connections where the pipe end is appropriately formed using the flaring method. The sleeve works with a properly selected nut and fitting, allowing the pressure to be transferred to the prepared pipe end. The product is used in power hydraulics, industrial installations, and during the construction and maintenance of machine piping systems.

The Ø38 size corresponds to an outer pipe diameter of 38 mm. It is one of the larger dimensions used in hydraulic pipe flaring systems. With such a size, the precision of the flare execution, proper support of the pipeline, and compliance of all connection elements become particularly important.

Application of Ø38 sleeve in hydraulic installations

The Ø38 intermediate sleeve is designed for making connections of rigid pipes in power hydraulics installations. Pipes with an outer diameter of 38 mm can be used in larger hydraulic lines, supply circuits, return circuits, and other sections of the installation, depending on the required flow diameter, pressure, and pipe wall thickness.

Elements of this type are used during the construction of industrial machine installations, hydraulic power packs, technological devices, and hydraulic systems of mobile machines. The sleeve can be used for creating new piping as well as during the repair or modernization of an existing installation, if its connection system is compatible with the sleeve's design.

What function does the intermediate sleeve perform in a flared connection?

In a flared connection, the end of the steel pipe is formed using an appropriate tool. The prepared flare works with the sealing surface of the fitting. The intermediate sleeve acts as a backup element for the nut, helping to transfer the clamping force to the formed pipe end. This solution allows for making a detachable pipe connection without using a cutting ring.

Correct operation depends on the mutual fit of the sleeve, pipe, nut, and fitting body. Incorrect flare geometry or elements belonging to different systems can lead to uneven pressure, deformation of the pipe end, and installation leaks.

Selecting the Ø38 sleeve for a 38 mm steel pipe

The primary selection criterion is the outer diameter of the pipe, which is 38 mm. However, it should be remembered that the Ø38 dimension itself does not determine all features of the connection. Before assembly, check the pipe wall thickness, flaring method, type of matching nut, geometry of sealing surfaces, and the operating pressure requirements of the entire system.

With larger pipe diameters, proper routing and support of the installation are also important. The weight of the pipe, machine vibrations, and stresses resulting from assembly should not excessively load the flared connection. Proper placement of clamps and avoiding forced pipe offsets help reduce the risk of damage during operation.

Ø38 sleeve vs. cutting ring – what are the differences?

The intermediate sleeve for flaring is not an equivalent of a cutting ring. In a flared system, the pipe end must be appropriately formed beforehand. In a cutting ring connection, however, a special ring clamps onto the outer surface of the pipe during nut tightening. Both technologies use different matching elements, so parts should not be swapped solely based on the same pipe diameter.

The Ø38 intermediate sleeve is also not used for crimping flexible hydraulic hoses. Ferrules for hoses are selected based on the nominal diameter of the hose, the number of braids, the rubber construction, and the type of hydraulic fitting.

Preparation of the 38 mm pipe and connection assembly

Before starting work, confirm the pipe dimensions and compatibility of connection elements. The pipe must be cut according to assembly requirements, deburred, and the end thoroughly cleaned. The sleeve and nut should be put on in the correct order, and then the flare should be made using a tool and die intended for the selected system.

After forming the end, check the symmetry of the flare and the condition of the sealing surface. Do not use pipes with cracks, dents, or deformations that could compromise tightness. The connection should be tightened according to the system manufacturer's requirements. After starting the installation, it is necessary to check for leaks under appropriate operating conditions.
