Quick overview

  • C Series commercial pumps Listed in the Purex and Pentair C Series commercial pump parts.
  • Genuine Purex part Part number 71423, supplied under the Pentair umbrella.
  • Second reference P24050 The listing also carries P24050, which is the number some parts diagrams use.
  • C-70 designation The listing shows C-70 alongside the part number, so match that against your own parts list before ordering.
  • Commercial duty seals matter On a commercial pump running long hours, a tired seal turns into a constant drip and a wet pad rather than a one off leak.
  • Fit it clean Clean the groove and use a silicone based O-Ring lubricant so the seal beds evenly instead of rolling.

Product details

Purex 71423 is an O-Ring listed as C-70 C Series P24050, catalogued in the Purex and Pentair C Series commercial pump parts. It is the genuine part, carried under Pentair since Purex came into the Pentair line.

Two numbers, one seal

This ring is carried as 71423 and as P24050. Older parts diagrams and distributor lists do not agree on which they show, so it is worth knowing both before you start matching numbers off a drawing. The C-70 in the listing sits alongside those numbers without further explanation, so treat it as part of the catalog description and confirm against your own parts list.

Why commercial pump seals get changed on schedule

A residential pump runs a few hours a day. A C Series commercial pump can run most of the day, every day, and seals age on run time rather than on the calendar. That is why a seal that would last years on a backyard pool becomes an annual item on a commercial installation. Change it while the pump is apart for other work, clean the groove, and use a silicone based O-Ring lubricant so the new ring seats without rolling out of place.

Questions and answers

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

What does C-70 in the name mean?
The source listing shows C-70 with the part number but does not explain it. It reads as a designation within the C Series listing, so check it against your own parts list rather than assuming it names a pump model.
What is P24050?
A second reference number carried in the listing for this same O-Ring. Parts diagrams may show either P24050 or 71423.
Which pumps is it for?
It is catalogued in the Purex and Pentair C Series commercial pump parts.
How should I fit it?
Clean the groove and the mating face, then fit the ring with a light film of silicone based O-Ring lubricant so it seats evenly and does not twist as the parts come together.
