Description
Replacement seal assembly engineered for 2.5 Horse Power pump impellers designed for 56 Frame wet ends produced by Intertek LX Brand, exclusively compatible with Jacuzzi® Premium and Sundance® brand spa systems. Compatible with pumps bearing part numbers 6500-352, 6500-365, 6500-367, 6500-845, 6500-357, or 6500-363 on their identification labels. Important: Some units may display WUA400-II designation, but Jacuzzi and Sundance models require this specific seal configuration. Key identification feature: this design positions the spring component on the rear of the impeller, while alternative models place the spring component on the volute housing. For alternative configurations, search our store for "Guangdong LX pump" components. Refer to our instructional video for proper installation procedures and verification that this component matches your system. Complete seal assembly specifications: 5/8" shaft diameter, 1.218" seal outer diameter, 1.250" seal outer diameter. Assembly includes spring seal component for impeller shaft mounting and ceramic with rubber component for volute installation. Both components feature approximately 5/8" center opening. Installation instructions: apply silicon sealant to impeller shaft, add small amount of The Professor's Silly Juice to shaft, then gently mount spring seal. The rubber component benefits from light silicon coating for smooth insertion into volute or wet end housing. Available individually, bundled with The Professor's Silly Juice (premium hot tub silicon sealer), or combined with impeller as complete kit. For impeller replacement needs, reference our Jacuzzi Premium 2.5HP Impeller Kit. This is the singular correct seal specification for Jacuzzi Premium and Sundance spa pumps manufactured after May 2009. CRITICAL: While this wet end appears visually similar to Aqua-Flo, Guangdong LX, and CMP wet end assemblies, components are NOT interchangeable—consult video for identification guidance!
