What to check before you order

This page does not say this part works in any particular housing or swaps for any other brand's part. Before ordering, compare these against what you use today:

  1. Size. This part is 1.8″ × 11.68″ (diameter × length). Check your housing's cartridge size or the label on the part you use today.
  2. Media. Polyamide compound (thin-film composite). If the part you use now has a different media, flag it so the change is a conscious one.
  3. Certification. The manufacturer's statement is shown word for word in the specification table. If your specification needs a certification for this exact part number, put it in your request.

Our spec comparison guide walks through each item.
