Upgrade the internal distribution system of your Jandy JS100-SM sand filter with the genuine Jandy R0488000 Hub Assembly featuring 30" Laterals. This factory-engineered assembly sits at the base of the filter tank and spreads return water uniformly across the entire sand bed, maximizing the media's ability to trap suspended particles and deliver visibly clearer pool water. Constructed from corrosion-proof materials rated for constant submersion in chemically treated water, this hub and lateral set is designed for extended, trouble-free service — making it a foundational component for anyone serious about maintaining top-tier filtration performance.

Key Benefits

• Genuine replacement for JS100-SM: Factory-dimensioned to seat correctly inside the Jandy JS100-SM tank, ensuring proper lateral coverage and flow geometry
• Includes 30" laterals: Full-length lateral arms distribute water evenly through the sand media, preventing channeling and dead zones
• Enhances debris removal: Maximizes sand-to-water contact time so fine particulates, oils, and organic matter are captured before returning to the pool
• Durable construction: Formed from rigid, chemical-resistant materials that hold up against years of continuous filtration duty
• Essential for system performance: Maintains the hydraulic balance your filter depends on to operate at its rated flow capacity and micron rating
