Product details
The Pentair 194989Z is a machined metal nut used on Pentair filters, listed as two required. It is the genuine Pentair part.
Which filter
The parts data for this nut carries two readings, and both are worth knowing before you order. It appears in the Pentair PacFab Nautilus DE filter parts listing, and it is also grouped under Pentair Sea Horse stainless cartridge filter parts. Check the parts breakdown for your own filter and match the position and the part number rather than assuming from the description alone.
Why use the OEM nut
Filter hardware holds a pressure vessel together. A machined nut of the correct thread, size and material keeps clamping force where the manufacturer intended it, which a similar looking fastener from a hardware drawer will not reliably do.
