Our Inflata-Void hose is a unique air mandrel assembly that becomes a rigid tubular void form when inflated with compressed air. Inflata-Void air mandrel systems use a rubber compound virtually impervious to the chemicals in concrete. This durability is combined with a proprietary reinforcement to provide controlled and uniform inflation along the entire length of the air mandrel assembly. Custom-engineered thermoplastic hose ends, one with an auto tire style inflation (Schrader) valve, complete the assembly. The thermoplastic hose ends can be field attachable and reusable to augment our product’s value further. Inflata-void air mandrel hose assemblies are often reused hundreds of times.
