The plastic wrench for the pre-filter lid nut is designed precisely for the thread of the nut of the Mr.Master pump. It allows correct tightening and loosening of the nut without the risk of slipping or damaging the plastic surfaces, which could occur when using an unsuitable tool.
Regular cleaning of the pre-filter basket is the basis of the correct function of the pump, and with this wrench the entire operation is quick and convenient. The wrench is long enough to provide the necessary torque without excessive strain.
Made of strong plastic resistant to moisture and chemicals, it guarantees a long service life of this auxiliary tool. We recommend storing it near the pump for immediate availability during maintenance.
