Description
The genuine Jandy Coupling Nut with O-Ring R0454000 is a 3-inch plumbing connection kit made for Jandy LXi and Legacy LRZE/LRZM pool and spa heater systems. Each package contains two coupling nuts paired with their corresponding O-rings, providing the components necessary to establish solid, drip-free joints at critical heater connection points. Built to exact Jandy factory dimensions, these OEM fittings guard against pressure loss and water seepage that can compromise heating efficiency. Keeping these connection points in top condition is fundamental to safe, consistent heater operation over the long haul.
