The Aquatemp Low-Flow Nut – Only 3.0 Inch Uni-Nut – 86-02370 is used on special low-flow or Saratoga heaters. These unique Aquatemp 86-02370 replacement nuts are designed to prevent leaking, like the nuts typically used in pools. This low-flow nut is used between the metal flange and the union nut of the heater. Its patented design allows the 86-02370 nut to flex so that it is more secure. The durable plastic design allows you to tighten it by hand.
