Davey - O-ring ProMatic ESR per raccordo cellulare - M1218

Davey – ProMatic ESR Cell Union O-Ring

This is the genuine Davey replacement o-ring (part number M1218) designed to seal the union nuts on the ESR electrolysis cell of the Davey ProMatic salt water chlorinator range. It prevents water ingress and leaks at the cell connection points, ensuring reliable, drip-free operation of your saltwater pool system. Replace this o-ring whenever the cell is removed for cleaning or replacement, or if you notice moisture around the cell unions.

Compatibilità

This o-ring is designed for use with the Davey ProMatic ESR, ESC, and MPS series salt water pool systems. It specifically seals the union nut connections on the ESR electrolysis cell. If you are unsure whether your model is covered, please check your system’s model number against the ProMatic ESR/ESC/MPS series before ordering.

Perché l'autenticità è importante

Using a genuine Davey o-ring ensures the correct material grade and dimensional tolerance for a perfect seal in a salt-water and chemically treated pool environment. Aftermarket substitutes may degrade faster or fail to seal correctly, risking water damage to surrounding equipment. Genuine Davey spare parts are manufactured to the same standards as the original components in your system.

Installazione

Before replacing this o-ring, always isolate power to both the controller and the pump. Carefully remove the cell union nut, extract the old o-ring, and seat the new one cleanly before re-assembling the union. Take care to avoid pinching or twisting the o-ring during installation. If in doubt, have the replacement carried out by a qualified pool technician.
