PTFE Streching tool
Technical features:
Weight: 6,24 kg • Size 36,5 cm X 36,5 cm X 9,5cm
Can be used at diameter range:40 mm - 250mm
How to use:
1. Heat the PTFE ring to 120 °C in an adjustable temperature electric furnace, until the PTFE ring becomes softer.
2. Set the nut on the tool to adjust the extent of maximal stretching.
3. Place the PTFE ring on the tool, then press down the handle firmly with even force.
4. Place the PTFE (and the o-ring) over the groove, and constrict the seal back to nominal size with a seal constrictor tool. (https://www.varitec.ro/en/products/seals/assembly-tools/calibrating-plier-for-ptfe-sealings)
5. Spare prism shaped stretching parts are also available.
