Replacement parts compatible with Hayward

An aftermarket Hayward-compatible part is manufactured to the same critical dimensions as the original but is not made by Hayward. 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.

Hayward numbers typically carry prefixes such as SPX, DEX, SP, ECX — 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.
