Pentair 35505-1429 O-Ring – Genuine Replacement Seal for Pentair Pool Equipment
The Pentair 35505-1429 O-Ring is a genuine replacement sealing O-ring designed to restore leak-free performance in compatible Pentair pool equipment. O-rings play a critical role in maintaining proper pressure, preventing air intrusion, and stopping water leaks at connection points within pumps, filters, and related components.
Over time, exposure to chlorine, heat, and pressure cycling can cause O-rings to flatten, crack, or lose elasticity. Replacing a worn O-ring with the correct Pentair OEM part helps ensure a proper seal, protects surrounding components, and keeps your pool system operating efficiently.
This O-ring is manufactured to Pentair’s exact specifications for fit, material quality, and durability, making it a reliable choice for both routine maintenance and repairs.
Why the O-Ring Matters
A failing O-ring can quickly lead to leaks, pressure loss, and equipment damage.
Why this matters:
-
Prevents water and air leaks at critical sealing points
-
Maintains proper system pressure and flow
-
Helps extend the life of pumps, filters, and housings
Replacing worn seals early can help avoid more costly repairs.
OEM-Quality Construction
The Pentair 35505-1429 O-Ring is made from pool-grade elastomer material designed to resist chlorine, heat, and continuous compression. Its flexibility allows it to seat properly while maintaining long-term sealing performance under normal operating conditions.
For best results, apply a thin layer of pool-safe silicone lubricant during installation.
Simple Maintenance Upgrade
This O-ring installs easily during routine service or equipment disassembly. Always remove the old seal, clean the sealing groove thoroughly, and inspect mating surfaces before installing the new O-ring.
Confirm compatibility with your specific Pentair equipment model before purchase.
