nstall an air vacuum in 2 minutes - no tools needed. Specially designed and engineered hose for hooking pressing machines to the air vacuum feed line. In normal position the hose is 15" long with 1-3/4" long cuffs (1-5/8" I.D.) at both ends that slip securely over standard 1-1/4" pipe and holds without clamping. A unique one-piece coil construction allows the hose to stretch to a full 36", providing for almost universal use of a single size of vacuum hose to meet practically any ordinary installation requirement. In the fully stretched position, it may be necessary to clamp the ends to the pipe and pressing machine. The hose allows movement of the machine in any direction for service, as it is extremely flexible and will not collapse, crimp or kink. One hose fits all applications.
