Compatibility and Fitment

Customers often visit Discount Pool Mart with questions about which gasket fits their small spa light. This section clarifies how to confirm the O-344 match.

How can I verify the O-344 fits my Pentair spa light?

Look for the 79108500 reference or confirm your fixture is a 4-inch SpaBrite, AquaLight, SAL Spectrum, or IntelliBrite unit. If so, the O-344 is the correct lens gasket. Bringing photos to the store helps staff confirm quickly.

Does the O-344 work on older American Products lights?

Yes, many older American Products-branded 4-inch spa lights share the same lens and housing dimensions. The O-344’s sizing aligns with these legacy models.

Can replacing this gasket help prevent condensation or water intrusion?

Yes, a worn or flattened lens gasket is a leading cause of fogging, moisture buildup, or full water leaks inside the light. Installing the O-344 typically resolves these issues.

Installation and Troubleshooting

Walk-in customers often ask how to seat the gasket correctly and how to check for a proper seal.

How do I install the O-344 on a 4-inch spa lens?

Clean the lens groove carefully, place the gasket evenly around the perimeter, and confirm it sits flat. Reassemble the lens and tighten the clamp or screws gradually for uniform compression.

What signs indicate my old lens gasket has failed?

Moisture behind the lens, flickering, or tripped breakers often point to water intrusion. A brittle or misshapen gasket should be replaced immediately.

How can I confirm the new gasket is fully sealed?

Once reassembled, the light should remain clear, free of fogging, and dry internally after several hours of operation. No bubbles or seepage should appear around the lens.
