Versatile & Economical: No other wrap strip product has RED's tested coverage and versatility. RED Wrap Strip not only handles the difficult plastics, it also handles flammable pipe insulations or anything else that requires a lot of intumescent expansion in a hurry. RED Wrap Strip saves money by requiring up to a 50% less wrap strip in common plastic pipe applications. BLU Wrap Strip not only handles the difficult plastics, it does so at a scale that no other product can match. Imagine sealing pipes up to 12" trade size or critical double containment piping? Now imagine doing it with less wrap strip and at a lower installed cost then other competing systems!
