Aladdin O-87 Universal 18" Filter Tank O-Ring

The Aladdin O-87 Universal 18 Inch Filter Tank O-Ring is designed to restore a consistent, watertight seal on a wide range of 18 inch single- and two-piece filter tanks. Its durable, chemical-resistant elastomer maintains flexibility under pressure, preventing leaks around the mid-clamp or lid band that can reduce operating efficiency. Molded to match the common sealing dimensions used across many sand and cartridge filter designs, the O-87 seats smoothly into the tank groove for secure closure during regular service. By maintaining a stable internal seal, it supports reliable pressure retention and dependable filtration performance throughout daily operation.

Compatibility and Fitment Details

Service professionals often confirm O-ring dimensions before heading to a job site. This section explains how to verify the O-87 for 18" tanks.

Is the O-87 designed to fit standard 18-inch filter tank grooves?

Yes, the O-87 is molded for common 18" grooves used across many sand and cartridge filters. If your tank diameter measures 18", this O-ring is likely the correct replacement.

Will the O-87 work for both clamp-style and split-tank filter designs?

Yes, its universal sizing supports various lid and clamp configurations found in popular filter brands. It seats evenly to provide uniform compression.

Can installing the O-87 help stabilize filter PSI?

Yes, a proper tank seal is essential for maintaining internal pressure. The O-87 helps eliminate air leaks that cause fluctuating PSI or reduced filtration.

Installation, Maintenance, and Service Preparation

Wholesale Pool Mart customers often purchase multiple seals in advance of routine service calls.

How should the O-87 be installed during tank maintenance?

Clean the tank groove, apply a thin lubricant, and position the O-ring without twisting. Tighten the clamp or lid band evenly to compress the seal fully.

What issues occur when a tank O-ring begins to fail?

Common symptoms include dripping near the clamp, air entering the system, or pressure instability. Replacing the O-ring with the O-87 typically corrects these issues.

How do technicians verify a correct seal after installation?

Stable filter pressure and absence of moisture at the clamp area indicate proper sealing. A balanced PSI reading confirms the O-ring is seated correctly.

Local Pricing, Stock, and Service Coordination

Customers often check several Wholesale Pool Mart locations before scheduling maintenance.

Is the O-87 typically stocked across nearby Wholesale Pool Mart stores?

Yes, it’s widely carried due to the frequency of tank-seal replacement on 18" systems. Checking local pricing helps technicians plan bulk purchases.

What information should I provide when calling for availability?

Give the tank diameter and show photos of the clamp or lid design. This helps staff verify that the O-87 is the correct part.

Do service pros commonly pair the O-87 with other replacement parts?

Yes, many also purchase cartridges, laterals, clamp kits, or pressure gauges to complete a full filter refresh.
