A Blow Gun on Every Hose! The new Coilhose CoBlo Coupler Blow Gun, 1/4" Industrial, 1/4" FPT (15CBG4F-DPB) is a combination quick coupling and blow gun in one! This convenient unit is perfect for metalworking or woodworking operations, which often produce shavings or sawdust making it difficult to view the work surface. A quick burst or two from the CoBlo™ allows the operator to get back to work quickly and easily without having to disconnect the tool, connect a dedicated blowgun and then reconnect the tool. The CoBlo can be used with an air tool connected or disconnected and is currently available in our most popular 1/4-inch Industrial, Automotive, Megaflow and ARO Interchanges.
