Abstract
A freeze plug installation tool adapted to be driven by a pneumatic driver is provided, preferably in kit form having a driver section which chucks into a pneumatic driver, one or several extensions shafts connectable to the driving section, and several freeze plug carrying heads which carry freeze plugs at various angles, so that by utilizing the kit in its various permutations numerous different combinations are provided which accomodate varying freeze plug installation situations involving hard to reach installation points.
Claims1
A freeze plug installation tool kit comprising:
- (a) a plurality of selectable head sections each having one end defining a ball which selectably swivel mounts a releasible freeze plug carrier and another end which is a connector end there being a shank between said connector end and said ball-defining end and the shank of each of said head sections having a bend defining a different angle than the shank of every other of said head sections;
- (b) a driver section having one end adapted to chuck into a pneumatic driver and another end which is a connector end;
- (c) a set of extension shaft sections of different lengths, each having two ends, both of which are connector ends adapted to releasibly connect to the connector ends of said driver section and any selected one of head sections to define one of numerous selectable single integral units when said selected head, shaft, and driver sections are connected together.
