The pre-filter lid nut is intended as a direct replacement for the Espa Niper and NOX 25 pool pumps. The part ensures a safe and hermetic closing of the pre-filter basket lid, thus preventing water leakage and loss of suction.
The original design guarantees a precise fit without the need for adjustments. Replacing this part extends the service life of the pump and maintains its optimum performance. Suitable for standard service work without specialist tools.
