Quick Product Summary

The Aladdin O-292-0 is an 11-inch replacement tank O-ring for Pac-Fab / Pentair Mitra equipment that specifies OEM part 313225. Aladdin’s current product data identifies O-292-0 with the Mitra / Pac-Fab family and cross-references it directly to Pentair 313225. Aladdin also uses O-292 as the tank O-ring in its Triton Mitra 60 sq. ft. cartridge-filter service kit. Additional parts listings identify 313225 / O-292 on Pac-Fab Mitra cartridge-filter and stainless separation-tank assemblies. Because these are legacy equipment families with multiple configurations, match the original service part number or the exact equipment diagram before purchase rather than selecting only by tank diameter or appearance.

Best For

• Pac-Fab / Pentair Mitra equipment calling for 313225
• Triton Mitra 60 sq. ft. cartridge-filter tank service
• Documented Mitra cartridge-filter tank sealing
• Documented stainless separation-tank assemblies using 313225 / O-292

Why This Matters

• The tank O-ring seals the joint between serviceable tank sections.
• A worn or distorted ring can allow leakage at the tank joint.
• Legacy Pac-Fab and Pentair equipment can use similar-looking tank seals with different part numbers.
• Matching 313225 helps reduce wrong-part orders and repeat disassembly.

Common Signs You Need This / Use This When

• The existing tank O-ring is cracked, flattened, stretched, hardened, cut, or missing.
• Water is leaking at the documented tank joint after the sealing surfaces have been inspected.
• Your equipment parts diagram specifies Pentair / Pac-Fab 313225.
• You are servicing a Mitra filter or compatible stainless separation-tank assembly that specifically lists O-292.

Product Specifications

Compatibility / Fitment Notes

Aladdin identifies O-292-0 as an 11-inch Mitra / Pac-Fab tank O-ring compatible with Pentair 313225. Its current filter-service kit documentation places O-292 on the Triton Mitra 60 sq. ft. cartridge filter. Other parts listings identify 313225 / O-292 on Pac-Fab Mitra cartridge filters and stainless separation tanks. Do not assume every 11-inch tank seal is interchangeable. Confirm the original 313225 reference or the exact filter / separation-tank parts diagram before ordering.

Installation / Use Notes

Shut the circulation system down and fully relieve pressure before opening any filter or separation tank. Remove the old tank O-ring, clean and inspect the O-ring groove and mating surfaces, and install O-292 without twisting, pinching, or overstretching it. Use only an O-ring lubricant approved for pool and spa equipment when appropriate. Reassemble the tank according to the equipment manufacturer’s instructions, restore circulation, and inspect the tank joint for proper sealing. Never open a pressurized filter or separation tank.

Buy with Confidence

Benchmark Pool Supply helps customers identify replacement filter parts by equipment family and OEM service number. For O-292, match the Mitra / Pac-Fab application to 313225 before ordering. This is especially important on older cartridge filters and stainless separation tanks where visually similar tank O-rings may use different part numbers.
