The YELLOW JACKET Alloy Ratchet Tube Bender Kit creates smooth and consistent bends when working with 1/4” to 7/8” soft copper, aluminum and light wall hydraulic tubing. The mandrel attachment ball-detent feature and color-coded mandrels make it easy to switch between different tubing sizes. The simple, yet powerful ratcheting mechanism is easy to actuate. The 63342 Reverse Bender, included in the 63325 Deluxe Kit, adds the capability to bend tubing from the outside of the bend.
