The Whirlpool WP3376846 Lower Spray Arm Seal prevents water leakage at the lower spray arm connection in compatible dishwashers. This replacement seal fits around the designated connection point, maintaining a proper seal while water flows through the spray arm during wash cycles. A secure fit supports consistent water pressure and distribution for effective dish cleaning. A worn, cracked, or damaged seal may cause leaks or reduce spray performance. Replacing the faulty seal restores proper sealing and supports reliable water flow through the lower spray arm assembly. Designed for compatible Whirlpool dishwashers, this component provides a practical solution for maintaining proper spray arm function.
