A pump lid O-ring may be small, but it plays a critical role in maintaining proper circulation and protecting the pump from air leaks. When the lid gasket becomes flattened, dry, or cracked, air can be drawn into the pump housing, causing loss of prime, noisy operation, and reduced flow. The Aladdin O-12 Gasket (O-12-0) is designed to restore an airtight seal on Sta-Rite and Jacuzzi pool pump lids, helping pumps run smoothly and efficiently.

This O-ring sits in the pump lid groove and seals the lid to the strainer housing. Over time, exposure to heat, chemicals, and repeated lid removal causes the gasket to lose elasticity. Replacing it with a properly sized, pool-grade O-ring ensures consistent suction and reliable pump operation.

This is a pump-specific lid gasket engineered for Sta-Rite and Jacuzzi pumps—not a generic hardware store O-ring.

Why the Pump Lid O-Ring Is Critical

The pump lid seal is the primary barrier preventing air from entering the suction side of the system. Even a minor air leak at the lid can affect performance and lead to bigger problems if ignored.

A worn or damaged lid O-ring can cause:

• Loss of pump prime

• Air bubbles returning to the pool

• Reduced circulation and filtration

• Loud or cavitating pump operation

• Increased wear on pump components

Installing a fresh Aladdin O-12 gasket restores the seal and helps protect the pump motor and internals.

Designed for Sta-Rite & Jacuzzi Pump Lids

The O-12-0 gasket is manufactured to match the correct diameter and cross-section required by Sta-Rite and Jacuzzi pump lids. Proper sizing is essential—an incorrect O-ring can pinch, twist, or fail to seal evenly.

Using a purpose-matched gasket ensures proper compression without over-tightening the lid.

Built for Pool Pump Operating Conditions

Aladdin gaskets are made from chemical-resistant, pool-grade rubber designed to withstand chlorinated water, heat, and repeated lid removal during routine maintenance. The gasket maintains flexibility, allowing it to seat properly and hold an airtight seal.

For service professionals, it’s a standard maintenance replacement. For pool owners, it’s an inexpensive part that prevents frustrating pump issues.

When to Replace the O-12 Pump Lid Gasket

This gasket should be replaced when:

• Air bubbles appear in the pump basket

• The pump struggles to hold prime

• The lid gasket looks flattened or brittle

• Water leaks around the pump lid

• Performing routine pump maintenance

Replacing the lid O-ring regularly helps avoid circulation problems and premature pump wear.

Practical Maintenance Part for Pool Owners and Service Professionals

For pool owners, replacing the pump lid gasket is one of the easiest ways to restore proper circulation. For service technicians, the O-12 is a common wear item used to resolve air-leak complaints quickly and reliably.
