The automobile manufacturers ¬increasingly rely on hose clamps with tight-fitting jaws, which are difficult to open with ¬conventional tools and hard to reach in very narrow areas. With the MUELLER hose clamp compressor and an ¬optional ¬bowden cable, each hose clamp can be opened quickly. The ¬flexible cables with different clamping jaws, can be attached to the ends of the hose clamps and opened instantly.
