Pentair 154493Z 6" Closure O-Ring for Triton II and Tagelus Filters

The Pentair 154493Z Closure O-Ring is a genuine replacement seal used on compatible Pentair Triton II and Tagelus sand filters. This 6" closure O-ring helps create a watertight seal at the filter closure or valve body connection, helping prevent leaks while the filter system is under pressure.

This O-ring is commonly replaced when the existing seal is flattened, cracked, stretched, leaking, or damaged during filter service. A properly sealed closure O-ring is important for maintaining filter pressure, preventing water leaks, and keeping the pool filtration system operating correctly.

Important Notes

• This item is the O-ring only.
• Filter lid, valve body, closure hardware, and other filter parts are sold separately unless otherwise stated.
• Verify your filter model and existing O-ring size before ordering.
• Do not reuse a damaged or flattened O-ring after servicing the filter.
• If the filter tank, lid, or valve body is cracked, replacing the O-ring alone may not stop the leak.

Installation Notes

• Turn off the pool pump before servicing the filter.
• Relieve all pressure from the filter before opening the tank or valve assembly.
• Remove the old O-ring and clean the O-ring groove before installing the replacement.
• Inspect the sealing surfaces for cracks, debris, sand, or scale buildup.
• Use only pool-safe silicone lubricant on the O-ring when needed.
• Do not use petroleum-based lubricants, as they can damage rubber O-rings.
• After installation, restart the system and check carefully for leaks.

Maintenance Tips

• Inspect the O-ring during each filter service or sand change.
• Keep the sealing area clean and free of sand, dirt, and debris.
• Replace the O-ring if it becomes stretched, cracked, flattened, or hard.
• Maintain proper pool water chemistry to help reduce scale buildup around filter sealing surfaces.
• Repair filter leaks promptly to help prevent water loss and equipment damage.
