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.

Questions and answers

What people ask about this product, answered by our pool techs.

What size is this o-ring?
The listing carries two readings: 6-3/4 inch inside diameter with a 1/4 inch thickness, and 6.35 inch by 6.9 inch. Measure the seal you are replacing if you need to be certain before ordering.
Which pumps does it fit?
Max-E-Pro Series, Dyna-Pro and Dyna-Pro E, plus the IntelliPro VS 3050, IntelliFloXF Variable Speed and WhisperFloXF pumps.
My pump will not hold prime. Is this the part?
It is the first thing to check. A trap cover o-ring that has hardened or taken a set lets air in at the lid, and the pump loses prime even though nothing else is wrong.
Can I just grease the old one?
Lubricant can buy a little time, but once the rubber has flattened into the groove or cracked, it will not seal again. Replace it.
