The plastic wrench for the pre-filter lid nut is a special accessory designed precisely for the pre-filter nut thread of InverPro pumps. It ensures proper tightening and loosening of the nut without the risk of slipping and damaging the plastic part.
Using the correct wrench extends the service life of both the nut and the pre-filter lid, as it prevents deformation of the surfaces caused by using unsuitable tools. We recommend using it every time you clean the pre-filter basket.
The wrench is made of sturdy plastic resistant to moisture and chemicals and has a sufficient lever length for comfortable opening even in the tight space of a plant room.
