7.0mm Punch for 400 Barb
This 7.0mm Punch is used to punch holes in your poly tubing for any 400 Barb fittings. The 400 barbs are compatible in our 3/4" or larger poly tubing.
To use this punch:
- Place tubing on ground or stable surface (do not hold in hand).
- Place punch cutting edge against tubing and push - careful twisting may be required to cut through tubing.
- After hole is punched, press the spring loaded ejector lever to clear debris from punch tip opening.
- Punch next hole.
*A little-known but valuable tip is to punch the holes in your poly tubing when it is cool/cold. If possible, try to punch holes in your tubing in the morning before the sun warms it too much.
