Primerus 1/8 Inch Punch
This easy to use punch offers an attractive adjustable wrist rope. Never spend time looking for your punch again. Professionals use this punch, with its specially designed punch tip, for making holes in mainline poly tubing to insert 1/8" poly tubing directly in without the use of a barbed coupler. After a short time the flexible poly will seal around the micro tubing creating a water-tight seal. This will also punch holes sized to insert any of the 1/4" barbed fittings into your mainline.
