Quick Overview

Pentair 77707-0119 Coil and Tubesheet Sealing O Ring Kit

Pentair 77707-0119 Coil and Tubesheet Sealing O Ring Kit

Anyone who has ever operated a pool knows that a perfect seal is essential to getting the right performance, flow, and function in place for your equipment. Over time, small leaks can develop into large problems, causing extensive damage to your system.

Inside every Pentair heater coil and tubesheet, there are o-rings that protect essential components from water exposure. If you've found that the o-ring has degraded (or disappeared over the winter), you'll be able to get the right replacement with Pentair.

Using the 77707-0119 Pentair Coil and Tubesheet Sealing O Ring Kit

The 77707-0119 Pentair Coil and Tubesheet Sealing O Ring Kit is a perfect match for the original o-ring in your heater, ensuring a perfect fit and tight seal. Each and every Pentair heater requires different internal o-rings. The 77707-0119 kit is suitable for use on Pentair MasterTemp 400LP and 400NA and Sta-Rite Max-E-Therm models 400LP, 400 NA, SR400LP, SR400NA.

Replacing the o-rings on this heater is a fast and easy job for any experienced heating professional. Be sure the 77707-0119 Pentair Coil and Tubesheet Sealing O Ring Kit is the right fit for your existing heater for a fast and easy replacement.

Used with:

• Pentair MasterTemp: 400
