Product Overview

The Pentair 191479 multiport valve stem O-ring is an important sealing component used within Pentair multiport valve assemblies. Positioned around the valve stem, the O-ring seals the internal valve mechanism to prevent water from leaking while the valve handle is moved between filtration settings.

Multiport valves control the direction of water flow through sand and D.E. filtration systems, allowing users to select functions such as filter, backwash, rinse, waste, and recirculate. Over time, valve stem O-rings may wear or degrade due to pressure cycles and exposure to pool chemicals. Replacing the O-ring helps restore proper sealing and ensures reliable valve operation within the pool filtration system.
