Aladdin O-83 O-Ring Gasket for Pump Unions

Replacement Seal Selection + O-83 Cross-References

• Aladdin O-83-0 aftermarket replacement O-ring for a correctly matched seal location.
• Manufacturer cross-references help identify compatible coupling and equipment applications.
• Published dimensions provide an additional check against the original seal.
• Replaces a missing or damaged O-ring when the exact equipment reference calls for O-83.

Quick Product Summary

The Aladdin O-83 O-Ring Gasket is an aftermarket replacement seal identified by the manufacturer as O-83-0. Aladdin lists coupling, bulkhead, diffuser, drain-cap and filter-rod applications across specific equipment references. For a pump-union repair, match the actual seal location and cross-reference before ordering; the store SKU for this listing is MS75XZP8WK.

Best For

Pool owners and service technicians replacing a worn seal whose equipment diagram or original part number cross-references O-83-0. It is useful when an assembly has been opened and the existing O-ring is damaged, flattened or missing. Compare the original seal and groove rather than assuming all pump-union gaskets share the same size.

Why This Matters

• A matching part number and seal location are more useful than choosing an O-ring by brand name alone.
• The same replacement reference can appear in different assembly types, so the equipment diagram remains important.
• A damaged sealing surface or incorrect assembly can require attention beyond fitting a new O-ring.

Common Signs You Need This / Use This When

• The required O-ring is cracked, split or visibly distorted.
• Inspection finds a missing seal in an assembly that specifies an O-83 cross-reference.
• A service diagnosis identifies the seal, rather than a damaged fitting or housing, as the part needing replacement.

Product Specifications

Compatibility / Fitment Notes

Use Aladdin’s O-83-0 cross-reference together with the exact equipment diagram and seal position. The manufacturer lists multiple equipment families and applications; that does not mean it fits every union on those brands. Verify the dimensions and original part number, especially when a used seal has stretched or deformed.

Installation / Use Notes

Shut down the equipment and follow its service and pressure-release instructions before opening an assembly. Inspect the sealing groove and mating surfaces, then install the correctly matched seal without twisting it. Use lubricant only when permitted by the equipment and seal instructions. Reassemble as directed and have persistent sealing problems assessed before returning the equipment to normal use.

Buy with Confidence

Benchmark Pool Supply identifies this seal by its Aladdin reference, store SKU and published dimensions. That combination helps you compare the replacement with the exact component required for the repair.
