A reliable pump lid seal is essential for maintaining proper suction and protecting the pump from air intrusion. When the lid gasket on a pool pump becomes flattened, brittle, or worn, air can enter the system, leading to loss of prime, noisy operation, reduced flow, and inconsistent filtration. The Aladdin G-345 Pump Lid Gasket (G-345-0) is designed to restore an airtight seal on Hayward Super II pool pumps, helping the pump operate smoothly and efficiently.

This gasket sits in the pump lid groove and seals the lid to the strainer housing. Because the lid is frequently removed for basket cleaning, the gasket is a normal wear item. Replacing it with a properly sized, pool-grade gasket ensures the lid seats evenly and maintains consistent suction after maintenance.

This is a pump-specific lid gasket engineered for Hayward Super II pumps—not a generic O-ring substitute.

Why the Pump Lid Gasket Is Critical

The pump lid gasket is one of the most common sources of air leaks in a pool circulation system. Even a small leak at the lid can impact overall system performance and lead to bigger issues if ignored.

A worn or damaged lid gasket can cause:

• Loss of pump prime

• Air bubbles visible in the pump basket

• Reduced circulation and filtration

• Noisy or cavitating pump operation

• Increased wear on pump components

Installing a new Aladdin G-345 gasket restores the airtight seal and helps protect the pump motor and internal parts.

Designed for Hayward Super II Pumps

The G-345-0 gasket is manufactured to the correct diameter and cross-section required by Hayward Super II pump lids. Proper sizing is critical—an incorrect gasket can pinch, twist, or fail to seal evenly.

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

Built for Pool Pump Operating Conditions

Aladdin pump gaskets are made from chemical-resistant, pool-grade rubber designed to withstand chlorinated water, heat, and frequent lid removal. The material maintains flexibility, allowing the gasket to seat properly and hold an airtight seal over time.

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

When to Replace the G-345 Pump Lid Gasket

This gasket should be replaced when:

• Air bubbles appear in the pump basket

• The pump struggles to maintain prime

• The gasket looks flattened, cracked, or brittle

• Water leaks around the pump lid

• Performing routine pump maintenance

Replacing the lid gasket regularly helps maintain proper suction and prolong pump life.

Practical Maintenance Part for Pool Owners and Service Professionals

For pool owners, replacing the pump lid gasket is one of the simplest ways to restore reliable circulation. For service technicians, the G-345 is a common wear item used to resolve air-leak complaints quickly and consistently.
