About This Item

The Pentair Flange 6" with Gasket & S/S Hardware (357263) is the OEM optional accessory flange kit for the Pentair EQ Series, CSP/CCSP Series, CSPH/CCSPH Series, 5CSP/5CCSP Series, and Aurora 3800 Series commercial pumps, providing a thermoplastic PVC socket-style 6-inch flanged connection at the pump suction or discharge port.

⚠️ IMPORTANT: THIS LISTING IS A KIT — NOT A SINGLE FLANGE
Part 357263 is a complete kit including the 6-inch thermoplastic PVC flange, a gasket, and stainless steel hardware. One kit is included per listing.

This flange kit mounts to the pump's ANSI flange port, creating a secure, leak-resistant pipe connection using a socket-style thermoplastic PVC interface. The included gasket seals the flange face, and the stainless steel hardware resists corrosion in wet commercial equipment environments. Without a properly seated flange and gasket, the pump connection is subject to leakage and pressure loss at the suction or discharge port.

Compatibility is based on Pentair parts documentation and available OEM records. This is not an exhaustive list. For certainty, verify the part number in your equipment's manual or on the original part itself before ordering.

Pro Tip

The 6-inch flange size is specific — confirm the flange port diameter on your pump before ordering. For EQ Series pumps, the flange port is located at the suction or discharge volute; for CSP/CCSP Series pumps, this kit is designed for the 6 in. x 4 in. ANSI flange port specifically. If your pump has a 4-inch or 8-inch port, a different flange kit is required. Check the port size and connection style (socket vs. threaded) against your pump's installation manual before adding to cart.
