The union nut for the BMSC salt cell is an original spare part designed for BMSC series salt chlorination units made by Monarch or Davey.
When correctly tightened, the nut provides a firm mechanical mounting of the electrolytic cell within the salt cell housing and prevents vibration loosening that could lead to salt water leakage or reduced disinfection performance.
Using an original part with matching dimensional tolerances guarantees a leak-tight seal and proper operation of the entire salt chlorination system, with no risk of premature corrosion or mechanical thread damage.
