A Wilbur Curtis 3375001987 Lock Nut holds sprayhead components firmly in place to maintain secure assembly and steady performance.
The lock nut secures the sprayhead in place so water is directed properly during the brew cycle. Its hex shape and 5/8" thread design provide a firm, precise fit that resists loosening from vibration and repeated heating cycles.
The lock nut may be failing if the sprayhead becomes loose, water flow turns uneven or brewing performance starts to vary. Physical signs can include stripped threads, visible wear or corrosion and environmental signs may include leaks, excess moisture around the sprayhead or movement caused by vibration.
