• Replacement union kit designed for compatible pool and spa plumbing applications.
• 2" slip connection allows solvent-weld installation to standard 2-inch PVC plumbing.
• 2" male pipe thread connection provides secure threaded attachment to equipment ports or fittings.
• Union design allows easier removal and servicing of connected equipment without cutting pipe.
• Helps maintain leak-resistant performance and stable hydraulic flow.

Product Overview
The Pentair 357603 2" Slip x 2" MPT Union Kit is a practical plumbing service component used to connect equipment to pool or spa circulation lines while preserving convenient future access for maintenance and repairs. The slip side is designed for standard 2-inch glued PVC plumbing, while the 2-inch male pipe thread side allows direct connection into compatible threaded equipment ports or adapters. Together, these connection types provide flexibility in plumbing layout and component integration.
The union-style design makes this kit especially useful in installations where pumps, heaters, filters, or other equipment may need to be removed or replaced without cutting rigid plumbing. Over time, union components can wear, crack, or lose sealing integrity due to pressure, chemical exposure, and repeated disassembly. Replacing compromised fittings with the 357603 union kit helps restore dependable plumbing connections, maintain proper flow, and support long-term serviceability in compatible pool and spa systems.
