The union nut is part of the quick-connect system of Emaux SS pumps, which makes it easier to disconnect and connect the pump during maintenance or replacement. It allows the pump to be removed within minutes without the need to cut or glue the piping.
The original part is made of durable plastic that withstands pool chemicals and UV radiation. The precise thread ensures a watertight joint and eliminates the risk of water leakage during operation.
It is recommended to replace union nuts whenever cracks or a damaged thread are visible that could cause water to leak at the pump connection point.
