Product details

The Pentair LA415 is the volute O-ring for the new style Letro booster pump. It is the genuine Pentair part, made of rubber.

What it seals

The volute is the housing that directs water off the impeller and out of the pump. The O-ring at that joint holds back the full booster pressure, which is considerably higher than a filter pump produces. When it hardens, flattens or nicks, the pump either drips at the seam or loses the pressure the cleaner needs to work properly.

When to replace it

Any time the booster pump is opened. An O-ring that has been compressed and heat cycled for a few seasons will not reseal reliably, and it is the cheapest part in the whole job. Confirm you have the new style booster pump before ordering, since the older version uses different parts.

Questions and answers

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

Which pump is this for?
The Letro booster pump, in the new style version. Pentair lists LA415 for that generation of the pump.
What does the volute O-ring seal?
The joint at the volute inside the booster pump. A failed O-ring there shows up as a leak or as a loss of pressure to the cleaner.
What is it made of?
Rubber.
Should I replace it during any teardown?
Yes. Once an O-ring has been compressed and heat cycled it rarely reseals properly, so it is worth renewing whenever the pump is opened.
