PVC Duct Hose made of spiral reinforcement of rigid PVC into fine grade soft PVC. Made available in Grey / Transparent / Blue colours. A moderately flexible light duty hose for collection and conveying of air, dust and light materials. Quality PVC compounding and production techniques have made the hose with better flexibility and service life than other commercial brands. PVC material, not being nature friendly, is slowly finding its way out of market. This is mainly due to the fact that PVC hose loses flexibility fast and develops cracks all over the hose. Very poor abrasion resistance also results in poor service life. However, PVC being chemically inert and inexpensive is still mostly preferred industrial duct hose in Asian and African countries, although Polyurethane (PU) hoses with steel wire reinforcement have started replacing PVC flexible duct hoses at an enormous speed.
