    Description

    This new design improves the wiping action and reduces grease spillage.

    Due to the unique reverse design, the line wiping efficiency is increased resulting in cleaner wire, minimising grease escaping from top of tool and providing a cleaner worksite/derrick.

    Excess grease is returned via a grease return line.

    The Enviro Stuffing Box and Line Wiper can be dressed for use with braided wire from 0.188" to 0.520" diameter and can be supplied for use with concentric (2"-10TPI) or solid (2"-6-60°) type flotubes.
