New Ratchet-Type Tube Wrenches Available In Larger Sizes{0602}
Usage:
Larger hydraulic tube fittings can now be more easily serviced using new ratchet-type tube wrenches with square drives. See Illustration 1. The short handle and 3/4" square-drive allow the wrenches to be used in confined locations in conjunction with several hand tools, such as extensions, breaker-bars, pipe extensions and torque wrenches. See Illustration 2.
These wrenches work on fittings for 1", 1 1/4" and 1 1/2" nominal tube diameters. They also work on plugs, 37 1/2° flare and "ORFS" type fittings. See chart.
