ABSTRACT:
An elastomeric protector boot for covering the lower housing of a hydraulically operated impactor tool characterized by air vents which are adapted to allow free air communication between the interior of the boot while preventing debris from entering the lower housing of the impactor. The protector boot further includes an internal foam rubber filter member for ensuring that foreign particles do not enter the annular space between the bit and the housing. The air vents are further protected from being snagged or torn through the provision of protection lobes which allow air communication between the air vent while preventing ingress of debris generated by operation of an impactor.
