Material Combinations

As LOKRING can join any tube materials with the same level of quality, you can
switch the components and tubes of the cycle system to the most feasible and
most cost effective material – regardless of brazing standards.

Description

The production of the joining requires no special preparation of the tubes and can be carried out by unskilled workers.The tool is connected to the LOKRING hydraulic aggregate by a 2.8 m hydraulic hose. The sizes of the clamping and assembly jaws are dependent on the dimensions of the tubes that are to be joined.

Line-short

Description

The aggregate is transportable and, according to its application, it is available at each workplace. The LOKRING tools are connected to the hydraulic aggregate by quick connections and hydraulic hoses. To actuate the aggregate, simply push the remote control switch that can be found on the tool. The hydraulic pressure is controlled by a switch and control gear, as well as control valves to the tools.

Line-short

Description

The hydraulic flaring tool is connected to the LOKRING hydraulic aggregate by two 2.8 m hydraulic hoses. The forward and backward movement of the flaring insert is enabled by means of a double acting cylinder. The size of the clamping jaw and the flaring insert depends on the outside tube diameter.

Line-short

  • Suitable tube material: Aluminium
  • Max. tube outside diameter: 1/2“ / 12.7 mm*
  • Max. tube wall thickness: 1.0 mm*
  • Working pressure: up to 320 bar
  • Flaring time: approx. 1 sec.
  • Weight: approx. 1.7 kg
  • Dimensions: 45 x 74 x 250 mm
