Description:
This bung wrench is designed to work with Phillipi's patented rubber barrel bung (pat. no. 194,721). The wrench is used to grasp and tighten or loosen the bolt which expands or contracts the bung. The wrench has hinged jaws which are closed by sliding down the cross handle. The wrench grips the bolt sufficiently to also enable it to extract or insert the bung in its contracted state.
