Pipe alignment clamps

Pipe alignment clamps are essential for quality electrofusion welds. They ensure the weld integrity is not compromised during fusion, and help to align clamps into the coupler during preparation.

We stock a range of Ritmo and Caldervale clamping setups, from simple strap clamps to rigid assemblies, with options up to 500mm OD. Contact us for more information, (08) 9303 2164 or

Extrusion welding shoes

Extrusion welding shoes are high grade Teflon blocks, shaped to suit the geometry of the desired weld. You can think of them as a trowel for your plastic welding extrudate.

Our Leister welding shoes cover all major seam geometries, for everything from container fabrication to overlap seam welding.

Spectex 2015 Expo

We stopped in to check out the SPECTEX 2015 show, held at the Melbourne Convention and Exhibition Centre recently.

We were keen to check out the new stationary welder from Leister, the SEAMTEK 36. We were impressed with how versatile the machine’s settings are, with control over the individual rollers, and a memory bank to store commonly used configurations.

The SEAMTEK 36 is ideal for workshop-based continuous seam welds in polyethylene, PVC and other thermoplastic textiles.
