The central rubber part (position 3) is an original replacement part for the titanium or stainless-steel Elecro G2 heat exchanger intended for heating pool water.
Its primary function is to ensure correct centring of the heat exchanger’s internal inserts and at the same time to seal the interface between the individual sections, thereby preventing the mixing of media or water leakage.
The rubber material resists high temperatures, the chemical environment of pool water and the pressure in the hydraulic circuit.
Replacement of this part is recommended during any major overhaul of the heat exchanger or if water leaks from the body of the heat exchanger.
