The Samco Stretch And Seal Tape is a clever tape made from self-amalgamating silicone. As you stretch the tape, it triggers a curing system, which causes the silicone atoms to actually cross-bond to each other forming a permanent, 100% leak proof join. No tool box or glove box should be without a roll of this fantastic tape!Self-amalgamating - no glue or adhesiveTemperatures from -50°C to over 200°CPermanent waterproof and airtight sealNo mess or sticky residuesLong shelf life - keep it in your tool boxCan wrap complex formsWraps over wet, dirty or oily surfacesExtra long 5m rollsDimensions: 30mm width x 0.5mm thick x length 5 metre
