Brief History & Usage:

The Pentair Coil/Tubesheet Sealing O-Ring Kit has been a vital replacement part for pool and spa owners seeking to extend the lifespan of their heaters. Over time, O-rings degrade due to heat, chemicals, and pressure, making timely replacement critical for preventing leaks and ensuring efficient heat transfer.

Electrical & Installation Tips:

✔ Turn off power & gas before installation to ensure safety.
✔ Remove the manifold & heat exchanger to access the old O-rings.
✔ Thoroughly clean sealing surfaces before installing new O-rings.
✔ Apply a small amount of pool-grade lubricant for a secure fit and longevity.
✔ Reassemble components carefully and check for proper alignment to avoid leaks.
