Waterway 400-6010 Pump Union | 2.5" x 2.5"

The Waterway 400-6010 Pump Union is engineered for dependable integration with spa and pool pumps that use a two and one half inch slip and two and one half inch nut connection point. Manufactured by Waterway Plastics to their established performance standards, the union fits pump ports measuring about three and five eighths inches in outside diameter and includes the required o-ring tailpiece to achieve a consistent, leak-resistant seal. Its PVC construction provides strong resistance to chemical exposure and the elevated flow demands of spa circulation systems. Designed to align with Waterway Executive fifty-six frame pump plumbing, the 400-6010 supports secure attachment while allowing convenient disassembly during pump service or replacement.
