Union Nut for the Discharge Port of ESPA Silen S and Silen S2 Pumps

The discharge port union nut is an original ESPA spare part designed exclusively for Silen S and Silen S2 pumps. It ensures a reliable, watertight connection between the discharge port and the connecting pipe with no risk of leakage even at higher operating pressures. The durable plastic with a precisely moulded thread allows the joint to be tightened and loosened repeatedly without damaging the threads. Replacing a worn nut extends the service life of the entire pump and prevents unnecessary water loss. The part is suitable for servicing and preventive maintenance of ESPA Silen pumps used in residential and commercial pools alike.
