77707-0011 Blower & Adapter Plate Gasket Kit

Ensure a safe, airtight seal on your heater’s combustion system with this genuine Pentair 77707-0011 Gasket Kit. This 4-piece replacement set is designed specifically for the blower and adapter plate assemblies in MasterTemp and Max-E-Therm high-performance heaters.

Over time, heat and pressure degrade the original seals, leading to efficiency loss or improper combustion. This kit provides a complete "drop-in" solution to restore your heater to factory-sealed specifications.

Kit Includes:

• Blower Gasket: For a secure seal between the blower and the adapter plate.
• Adapter Plate Gaskets: To ensure the transition to the burner manifold is airtight.
• Essential Hardware Seals: All four gaskets required for a complete top-end service.

Compatible Models:

• Pentair MasterTemp: 175, 200, 250, 300, 400 (NA and LP models).
• Sta-Rite Max-E-Therm: SR200, SR333, SR400 (NA and LP models).

Why Replace These Gaskets?

• Safety First: Prevents dangerous exhaust gas leaks within the heater cabinet.
• Optimize Efficiency: Maintains correct air-to-fuel ratios for clean, fast heating.
• OEM Reliability: Precision-cut from high-temp resistant material to outperform generic aftermarket alternatives.

🚩 PRO TIP: The "Photo First" Method Before disassembling the blower assembly, snap a photo of the wire harness and gas valve orientation. This makes re-sealing the system with your new 77707-0011 kit a breeze and ensures a correct, hassle-free process!
