Restore proper combustion performance in your Pentair pool heater with this genuine Pentair Air Orifice Kit. Built with factory-spec precision, the orifices in this kit carefully control the air-to-gas mixture feeding into the burner, promoting efficient heat output and consistent temperature delivery. When your heater's orifices wear or become obstructed, combustion suffers and heating times increase. This direct-fit kit returns your Mastertemp or Max-E-Therm unit to its original operating standard, helping you get faster warm-up times and more reliable day-to-day performance. Straightforward to swap in, the kit includes everything needed for a complete replacement.

Key Benefits

• Precision Air-Gas Control: Factory-engineered orifices deliver the exact air-to-gas ratio your heater needs for clean, efficient combustion.
