A leaking pump lid or trap cover is one of the most common causes of air entering a pool system and loss of prime. The Aladdin O-12-0 Pump Lid or Trap Cover O-Ring is a precision-engineered 6-inch replacement seal designed to restore a tight, leak-free connection on a wide range of pool pumps and trap covers.

Manufactured to replace several OEM part numbers—including Hayward® SPX3000S, Jacuzzi® 47-0438-07-R, and Pentair® / Sta-Rite® U9-375—this O-ring delivers OEM-equivalent fit, compression, and durability. It is commonly used on pump lids and trap covers where consistent sealing pressure is critical to maintaining proper circulation and filtration.

At Benchmark Pool Supply, worn lid O-rings are one of the most frequent causes of service calls we see. Heat, suction pressure, and chemical exposure cause older seals to flatten or harden over time. Replacing the seal with the Aladdin O-12-0 helps eliminate air leaks, stop water seepage, and protect pump motors from running dry.

Manufactured from pool-grade elastomer, this O-ring is built to withstand chlorinated water, pressure cycling, and seasonal temperature changes.

Designed for 6″ Pump Lid & Trap Cover Applications

The Aladdin O-12-0 O-Ring is specifically sized for 6-inch pump lids and trap covers, providing even compression around the entire sealing surface. Its profile ensures proper seating without twisting or pinching during installation.

Common applications include:

• Pump lid O-rings

• Trap cover sealing O-rings

• Strainer pot lids on residential pool pumps

Compatible equipment commonly includes Dura-Glas®, Dyna-Wave®, Maxi-Glas, Max-E-Pro®, Super II™, and similar pump platforms.

Why Replacing Pump Lid O-Rings Matters

Pump lid and trap cover O-rings are exposed to constant suction and pressure changes. When these seals fail, common symptoms include:

• Air bubbles returning to the pool

• Loss of pump prime

• Water leaks around the pump lid

• Reduced circulation and filtration efficiency

Replacing worn seals with the Aladdin O-12-0 O-Ring is a simple, low-cost maintenance step that prevents bigger equipment issues.

This O-ring is designed specifically for swimming pool applications and maintains elasticity under continuous operation. It is ideal for both professional service technicians and DIY pool owners.

Recommended for:

• Seasonal pump maintenance

• Trap cover resealing

• Professional pool service repairs

• Preventive maintenance on older pumps
