Brower OM5R Rubber Drain Plug – M530 Automatic Waterer

The Brower OM5R is a rubber drain plug made specifically for the Brower M530 automatic waterer, sealing the trough tight while still giving you quick, tool-free access whenever it's time to clean. Rubber plugs wear down with repeated use and exposure to sun, cold, and constant moisture, which can lead to slow leaks or a plug that no longer seals properly. Replacing the OM5R restores a solid seal, so your M530 keeps holding water reliably instead of dripping it away between cleanings. Since the OM5R is removable by design, cleaning your trough stays simple, so there's no reason to skip regular maintenance.
