Product details
This is the trap cover o-ring, part number 35505-1440Z, used on the Max-E-Pro Series, Dyna-Pro and Dyna-Pro E pumps as well as the IntelliPro VS 3050, IntelliFloXF Variable Speed and WhisperFloXF.
The seal that holds prime
The strainer pot runs under suction, so any gap at the lid pulls air rather than leaking water. That is why a worn trap cover o-ring shows up as a pump that will not stay primed, or a basket that fills with air while the pump is running, instead of as a puddle on the pad.
Sizes on record
Our sources give this seal two size readings: 6-3/4 inch inside diameter with a 1/4 inch cross section, and 6.35 inch by 6.9 inch. Both are recorded here rather than one being chosen. If exact dimensions matter for your application, measure the seal in your hand before ordering.
Service note
The lid comes off every time the basket is emptied, so this seal sees more handling than almost any other part on the pump. Keep it lubricated with a pool grade o-ring lubricant and replace it as soon as it stops springing back.
