O-492 | Aladdin Sta-Rite Light Lens Gasket

The Aladdin O-492 Light Lens Gasket is a high-quality replacement gasket designed to meet original OEM specifications for many of the light housings used by Sta-Rite / Pentair pool and spa lights (including series like SunBrite and SunGlow). This generic gasket features a 7-1/4 inch inside diameter and an 8 inch outside diameter — dimensions that align with standard Sta-Rite/Pentair lens assemblies. Because it matches the original lens-seal dimensions and materials, this gasket supports easy DIY replacement during light maintenance, lens cleaning, or after lens-ring replacements. Many dealers list it as a direct replacement for OEM part numbers like 05501-0001 and 05501-0007

Highlights

• OEM-Spec Dimensions: Inside diameter of 7-1/4″ and outside diameter of 8″ — ideal for Sta-Rite / Pentair SunBrite and SunGlow light housings.

• Watertight Protection: Forms a tight seal around the lens rim to block water intrusion, protecting internal light components from corrosion or electrical damage.

• Chemical-Resistant Rubber: Elastomer material resists chlorine, pool chemicals, heat, and prolonged submersion while maintaining flexibility and sealing integrity.

• Easy Replace & Re-seal: Installs easily during light servicing or lens-ring replacement and restores original sealing performance — a solid maintenance part for pool owners.

• OEM Part Replacement: Direct fit for several OEM part numbers (05501-0001, 05501-0005, APCO2265, etc.), making it a reliable alternative for older or worn out light-lens seals.

Additional Info

The Aladdin O-492 Light Lens Gasket replaces several Sta-Rite and Pentair OEM seals, including common SunBrite and SunGlow light-housing gaskets such as 05501-0001 and 05501-0007.

This FAQ helps walk-in customers at Discount Pool Mart confirm compatibility, understand installation steps, and troubleshoot moisture-related issues before picking up the O-492 in store.

Compatibility and Fitment

Customers frequently bring older light fixtures into Discount Pool Mart to match the correct gasket. This section clarifies how to confirm the O-492 fit.

How do I verify the O-492 fits my Sta-Rite or Pentair light?

Check whether your existing gasket measures about 7-1/4 inches inside and 8 inches outside, or look for OEM references like 05501-0001 or 05501-0007. If these match, the O-492 is the correct lens gasket. Bringing photos helps staff confirm quickly.

Does the O-492 work on SunBrite and SunGlow light housings?

Yes, these light families share the same lens-ring dimensions. The O-492 seats cleanly into the groove and supports a uniform seal.

Can replacing the O-492 resolve fogging or moisture inside the lens?

Often yes. Fogging, moisture beads, or rusting screws typically indicate a deteriorated gasket. Installing the O-492 usually restores a watertight barrier.

Installation and Troubleshooting

Walk-in customers often ask how to seat the gasket and what symptoms indicate gasket failure.

How do I install the O-492 during lens servicing?

Remove the lens ring, clean the groove thoroughly, and place the gasket evenly around the lens. Tighten the retaining ring gradually to compress the gasket uniformly.

What signs show the old gasket is worn out?

Common symptoms include water behind the lens, flickering lights, or tripping breakers. A stretched, cracked, or flattened gasket should be replaced immediately.

How can I confirm the new gasket is sealing properly?

After powering the light, the lens should remain clear with no moisture present. Consistent clarity indicates proper sealing.

Is the O-492 usually available for pickup at Discount Pool Mart?

Yes, it is a commonly stocked gasket due to widespread SunBrite and SunGlow light installations. Calling ahead helps confirm availability.

Should I bring my old lens gasket to the store?
