Intermediate sleeve for flaring hydraulic pipes – 6 mm

The intermediate sleeve (6mm) for flaring is a hydraulic fitting component designed for making connections of rigid steel pipes with an outer diameter of 6 mm. It works with a properly formed pipe end, a nut, and a matching connector. Its task is to support the flare and transfer the pressure during the tightening of the connection. The small size (6mm) makes these types of components suitable for use in compact hydraulic installations, control systems, measuring lines, and during the repair of precision pipe connections.

Technical parameters of the 6mm intermediate sleeve

Product type: intermediate sleeve for pipe flaring.
Size: 6mm.
Outer diameter of the matching pipe: 6 mm.
Connection type: pipe, flared.
Intended use: rigid steel pipes for hydraulic installations.
Function: flare support and cooperation with the nut.
Matching elements: 6mm pipe, matching nut and connector.
Area of application: power hydraulics, control and measuring systems.

Application of the 6mm sleeve in precision hydraulic installations

The 6mm sleeve is used when making connections of small-diameter steel tubing. Such tubes can be used to conduct media in hydraulic control systems, monitoring and measuring installations, auxiliary circuits, and compact hydraulic units. The suitability of a specific connection depends on the installation requirements, including pressure, pipe wall thickness, and the type of connector used.

Flared connections for 6 mm pipes can be found in machine tools, hydraulic power units, industrial equipment, and auxiliary machine installations. The intermediate sleeve allows for completing a disconnectable connection, which can be used during the construction of a new installation or the replacement of a damaged pipe section.

How does the intermediate sleeve work in a flared connection?

In a flared system, the end of the steel pipe is formed using an appropriate tool. The resulting flare works with the sealing surface of the connector. The intermediate sleeve is located on the nut side, providing support for the formed end and allowing the transfer of clamping force during tightening.

The tightness of the finished connection depends on the correct execution of the flare, the fit of the matching surfaces, and the compatibility of all components. The sleeve does not constitute an independent seal. It should only be used with fittings intended for the specific flaring system.

Selecting the 6mm sleeve for a 6 mm steel pipe

The basic selection dimension is the outer diameter of the pipe, which is 6 mm. However, its wall thickness, the type of flare being made, the nut design, and the connector geometry should also be checked. Pipes with the same outer diameter can vary in wall thickness, so not every pipe will be suitable for the same method of end forming.

The 6mm designation indicates the pipe diameter but does not automatically determine the nut thread or the sealing surface angle. When assembling fittings, ensure that the sleeve, nut, and connector body belong to a compatible connection system.

Flaring 6mm pipes – accuracy of end preparation

For 6 mm diameter pipes, precise edge preparation is of particular importance. Small cutting irregularities, burrs, or asymmetrical flaring can make it difficult to achieve a tight connection. The pipe end should be cut perpendicularly to the axis of the tube, cleaned, and prepared according to the requirements of the flaring tool.

Before forming, the nut and the sleeve must be placed on the pipe in the correct order. An appropriate die, matched to the pipe diameter and the selected connection system, must be used to create the flare. The finished end should be checked for symmetry, cracks, creases, and damage to the sealing surface.

Flaring sleeve vs cutting ring

The intermediate sleeve 6mm is not a replacement for a 6L, 6S, or 6LL cutting ring. In a flared connection, the pipe end is pre-formed, and the sleeve works with the prepared flare. In a cutting ring system, an appropriate ring clamps onto the outer surface of the pipe during assembly. These components belong to different systems and require compatible connectors.

The 6mm sleeve should also not be confused with a crimp sleeve intended for swaging flexible hydraulic hoses. The product described is used for connections of rigid steel pipes.

Installation and leak test of the 6mm connection

Before starting work, the hydraulic system must be safely depressurized. The pipe should be positioned coaxially with the connector, without stress or forced deformation. The nut should be tightened according to the requirements of the system used. Excessive pressure should not be used to correct a poorly formed flare.

After completing the installation, check the stability of the pipe routing and perform a leak test according to the procedure applicable to the installation. In systems exposed to vibrations, it is important to properly support the lines so as not to transfer excessive loads to the connector.

Frequently Asked Questions (FAQ)

Which pipe does the 6mm intermediate sleeve fit?

The 6mm sleeve is designed for flared connections of steel pipes with an outer diameter of 6 mm. You should also check the wall thickness and the compatibility of the other connection components.

Is the 6mm sleeve suitable for measuring systems?

It can be used in measuring systems using appropriately selected flared connections of 6 mm pipes. Permissible working conditions depend on the parameters of the complete connection.
