Canon Ink Tank Seal Cutter (4mm Dia Neoprene cord) After refilling your Canon CLI 8 ink tank, you'll need to seal the filling hole, which is 4mm in diameter. The best way to do this is by using a neoprene sponge cord with a closed cell structure that's 4mm in diameter. This can be purchased on eBay at https://www.ebay.co.uk/itm/NEOPRENE-SPONGE-CORD-CLOSED-CELL-3mm-4mm-5mm-6mm-7mm-8mm-1MTR-LENGTH/121060170862?ssPageName=STRK%3AMEBIDX%3AIT&var=420119140779&_trksid=p2057872.m2749.l2649. Using this neoprene seal will make it easy to remove the filling hole for further refills, and no glue is required. You can also add aluminum foil sticking tape on top of the neoprene seal if you want extra security. The design for this seal cutter was created using DS DesignSpark Mechanical. To assemble the seal cutter, you'll need the following items: - A Stanley Knife Blade STD - Two 3mm Dia x 6mm screws to hold the blade in place - Three 3mm nuts to secure the blade - One 3mm Dia screw that's 15mm long
