Pentair Coil and Tubesheet Sealing O-Ring Kit
Proper sealing is one of the best ways to keep all of your pool and spa equipment in good shape, and this is especially true for your pool or spa heater. Water flow can be damaging to any element of your pool, but the components of your heater can be particularly sensitive to leaks.
If you've discovered that the seals around your coil and tubesheet have been damaged or corroded over time, it is very important that you replace them - even if your heater is still functioning. Over time, a leak can damage your tube sheet, leading to a costly repair (or even the need to replace your heater). Luckily, if you have a Max-E-Therm or MasterTemp pool heater, you can rely on Pentair to provide you with the replacement o-rings that you need.
The 77707-0118 Pentair Coil and Tubesheet Sealing O-Ring Kit is designed to provide an exact replacement and perfect seal for MasterTemp heater models 300 NA and 300 LP and Max-E-Therm model 333. This essential component of your heater ensures a tight seal that allows each component of your heater to function as it should.
For any pool heating professional replacing an o-ring is a fast and easy job that can be completed quickly. Be sure that the 77707-0118 Pentair Coil and Tubesheet Sealing O-Ring Kit is the right match for your current heating equipment, and you'll have your heater running leak-free after a quick repair.

- Pentair MasterTemp 300 LP, Pentair MasterTemp 300 NA (MSTRTMP300LP, MSTRTMP300NA)
- Sta-Rite Max-E-Therm 333 LP, Sta-Rite Max-E-Therm 333 NA (SR333LP, SR333NA)
