Jandy O-Ring, Energy Filter Replacement, R-Kit R0374500 Ring Prevents Internal Leaks & DamageThe Jandy R0374500 Energy Filter O Ring Replacement Kit is a genuine OEM seal kit designed for Jandy Energy Filter systems. Proper O ring sealing is critical to maintaining internal filter pressure, preventing water leaks, and ensuring consistent filtration performance. Over time, O rings lose elasticity due to heat, pressure cycles, and chemical exposure. Flattened, brittle, or cracked seals can allow air intrusion or water leakage at the tank seam.
