Pentair 2" HiFlow Multiport Valve Diverter Seal / Spider Gasket | 272409Z
The Pentair 272409Z HiFlow Multiport Valve Diverter Seal is a genuine OEM replacement spider gasket designed for select Pentair and Pac-Fab 2-inch HiFlow pool and spa multiport valves. This essential sealing component helps prevent internal water bypass between valve passages, maintaining proper filtration, backwashing, rinsing, and waste functions.
Manufactured to Pentair's original equipment specifications, the 272409Z replaces damaged, worn, or deteriorated diverter seals in compatible HiFlow valve assemblies. A properly installed spider gasket helps restore correct water flow through the selected valve position and prevents unwanted water loss through the waste line.

Signs Your Multiport Valve Spider Gasket Needs Replacement
A worn or damaged spider gasket can allow pool water to travel between valve passages even when the selector is positioned correctly. Common symptoms include:
- Water continuously leaking from the waste line while the valve is in FILTER mode
- Reduced filtration efficiency from internal water bypass
- Unexpected water movement between valve passages
- Cracked, torn, flattened, or deteriorated gasket material
- Loose or displaced spider gasket inside the diverter assembly
- Water leaking to waste during normal pool circulation
These symptoms may also be caused by a damaged diverter, spring, or valve body. Inspect all internal valve components before replacing the seal.
Installation Instructions
- Turn off the pool pump and disconnect electrical power.
- Relieve all pressure from the pool filtration system before opening the valve.
- Remove the multiport valve top assembly according to Pentair's service instructions.
- Inspect the diverter and carefully remove the old spider gasket.
- Thoroughly clean the gasket groove and remove all old adhesive and debris without damaging the valve components.
- Inspect the new Pentair 272409Z gasket for proper fit.
- Install and secure the gasket using a manufacturer-approved cyanoacrylate adhesive suitable for rubber-to-plastic bonding, following Pentair's instructions.
- Allow the adhesive to cure completely before reassembling the valve.
- Reinstall the valve top assembly and confirm the components are correctly seated.
- Restart the filtration system and inspect for proper valve operation and leaks.
Installation Note: This diverter seal must be properly secured during installation. Follow Pentair's adhesive application and curing instructions. Do not use excessive adhesive or install the gasket over old adhesive residue.
