AMT 1567-002-00 #226 Buna-N O-Ring
The AMT 1567-002-00 is the genuine replacement #226 Buna-N O-ring, listed in CLR Marine’s catalog for the AMT Primo pump line. It is a small part with an outsized job: it sits in a machined groove and, when the joint is torqued down, deforms just enough to fill every imperfection in both faces and block the path a leak would take.
Buna-N (nitrile) is the standard elastomer for water and general utility service. It handles water, most detergents and mild solutions, stays flexible through normal operating temperatures, and stands up to the abrasion that comes with dirty liquid better than many alternatives. Where it struggles is with high heat, ozone and strong oxidising chemistries — duties where Viton or EPDM rings are specified instead.
Treat this as a single-use part. An O-ring that has been clamped in a groove takes a permanent compression set, and refitting it means the joint will not seal to the same load — on a self-priming pump that usually shows up as a slow weep, then air ingestion, then a pump that runs but will not lift. Fit a new ring every time the joint is opened, clean the groove properly, and check the part number against your parts list, since AMT uses several O-ring sizes that look nearly identical.
