The union nut is part of the connection fitting of the Badu Magic pump and serves to firmly tighten the flange ring and the seal at the point where the piping enters or exits the pump body.
This genuine product from STP fittings s.r.o. is made of a durable polymer resistant to pool chemistry. The precisely defined thread allows easy hand-tightening as well as easy loosening without the risk of seizing.
It is advisable to replace union nuts preventively during any major repair or disassembly of the pump. The genuine part ensures correct contact with the seal and eliminates the risk of leakage that would reduce the pressure in the hydraulic circuit.
