Spare Parts & Flat-Base Diodes

Keep Your Rectifiers Running with Genuine Spare Parts

Australian Rectifiers maintains a large inventory of spare parts for electroplating rectifiers at our Melbourne warehouse. We stock flat-base rectifier diodes, thyristors, semiconductor fuses, control boards, busbars, and cooling components — with a focus on parts compatible with O'Donnell Griffin and Westinghouse rectifiers that are still widely used across Australian electroplating and anodising operations.

Our service department is not limited to our own products. We service, repair, and maintain rectifiers from most major manufacturers, drawing on 37+ years of specialist experience. Whether you need a single replacement diode or a complete overhaul of a legacy rectifier system, our technical team can help.

We also stock amp hour meters for electroplating process control, and maintain an inventory of used and refurbished rectifiers — fully tested and warranted — for customers seeking cost-effective solutions or emergency replacements.
