Features

• OEM Pentair #2-259 O-ring for 3-port valve assemblies.

Description

A worn valve O-ring can cause leaks, internal bypass, and reduced filtration efficiency. The Pentair 071427Z is an OEM #2-259 O-ring designed for 3-port valve assemblies in SM and SMBW filter systems.

This durability-focused replacement restores proper sealing within the valve body, ensuring correct water flow during filtration and backwash cycles. It is a simple but critical component for maintaining system performance and reliability.

Pro Tip

When servicing the valve, inspect the diverter and compression ring as well. Replacing all worn sealing components together helps prevent repeat leaks.

Installation Tips

Shut off system pressure before disassembly. Clean the valve groove thoroughly, lightly lubricate the O-ring with pool-safe lubricant, and seat evenly to avoid pinching during reassembly.
