Overview
Are you looking for a ventilation and exhaust hose that is both robust and durable, with excellent safety performance? Our PVC spiral flame-retardant hose is the ideal choice.
This hose is made of high-quality materials with an internally embedded, sturdy steel wire spiral skeleton, forming a unique pipe wall structure. It's more than just an ordinary pipe; it's a complete pressure-resistant, flame-retardant, and corrosion-resistant air delivery system.
Its core advantage lies in the perfect combination of "spiral" and "flame retardancy." The steel wire spiral structure gives it excellent pressure resistance and flexibility, making it resistant to crushing; while the special flame-retardant PVC material effectively prevents the spread of flames, adding a solid firewall for your operational safety.
