BlastOne Supaflex blast-hose is manufactured from virgin rubber for extended life. Carbon black is added for static dissipation. With a high quality hose, life is 400 to 500 hours. BlastOne Supaflex is manufactured to our specifications to give you longevity and flexibility. If you need to run blast-hose longer then 20 meters, add heavy wall extension hoses. As a rule of thumb, use a blast hose that has an ID minimum of 3 times larger than the nozzle size.
