Applications & Compatibility
This O-ring is intended for use when the original lid seal on an automatic chemical feeder is worn, cracked or leaking. It fits several Pentair feeder models that use this cap-style O-ring. Always verify your feeder model to ensure compatibility.
Installation Instructions
- Turn off the chemical feeder and isolate its water flow before servicing.
- Remove the lid or cap from the feeder housing and drain any remaining chemicals safely.
- Remove the old O-ring, clean the grove and lid sealing surface thoroughly.
- Lightly lubricate the new R172009Z O-ring with pool-safe lubricant and position it correctly in the groove.
- Reinstall the lid and restore flow; check for leaks around the seal after startup.
Troubleshooting
- Leak around feeder lid: Check that the O-ring is seated flat, the lid threads are clean, and the seal surface is undamaged.
- O-ring extruded or flattened: Ensure your feeder lid is properly aligned and torque is correct; inspect the groove for damage.
- Chemical smell or vapor escape: Replace the O-ring if it shows signs of hardening, cracking or discoloration.
Maintenance Tip
Inspect the lid O-ring annually during your chemical feeder maintenance routine. Replace the R172009Z O-ring if it appears hardened, cracked or is no longer sealing properly to maintain safe and leak-free operation.
