Replacement parts compatible with Pentair

An aftermarket Pentair-compatible part is manufactured to the same critical dimensions as the original but is not made by Pentair. We check every part against an OEM sample for thread pitch, port geometry and sealing surfaces before tooling is approved, so it installs without modification.

Pentair numbers typically carry prefixes such as C, FNSP, EC, O — the number is usually molded into the part or printed on the equipment label. Enter it above to find cross-referenced replacements.

Before committing to a container, distributors should confirm fitment by OEM number, equipment model, and thread or port size. We supply photos, dimensional drawings and, on key parts, 3D models — plus samples for validation ahead of bulk production.
