The 2″ Heater O-Ring is a water-resistant seal designed for use around 2″ heater element housings and plumbing connections. It helps ensure a tight, leak-free seal between the heater and adjoining pipework or fittings, supporting safe and efficient spa operation.
Made from durable gasket material, this O-ring withstands heat, water chemistry, and repeated compression to maintain a reliable seal over time.
