Used, Refurbished & Surplus Automation Parts

Tested surplus, used and refurbished automation parts — bench-tested, condition-graded, 12-month warranty.

Overview

TGK Parts supplies used (surplus) and refurbished industrial automation parts for maintenance, repair and emergency replacement — at 40–70% below new list price. Our stock covers PLC modules, VFDs, HMI panels, servo drives, sensors and power supplies from Siemens, Allen-Bradley, Mitsubishi, Omron, ABB and Schneider Electric.

Every used or refurbished unit passes our five-step bench test before shipping and ships with a 12-month warranty — the same warranty we give on new stock. For parts that are no longer manufactured, see our obsolete & discontinued parts sourcing service.

FAQ

Do refurbished parts come with a warranty?

Yes — 12 months on every used and refurbished unit, the same as our new stock. If a unit fails in service within the warranty period, we replace it.

Where do your used parts come from?

From surplus dealers, factory decommissioning, OEM liquidation and system integrators. Every unit is bench-tested and graded before it is listed.

Can I see the actual condition before buying?

Yes — on request we send photos of the actual unit and its nameplate. Grade B and C items always ship with photo documentation.

Do you sell used parts in bulk for a retrofit project?

Yes — send your parts list (MPN + quantity) and we quote used, refurbished and new options side by side so you can balance cost against criticality.

Is a refurbished drive as reliable as a new one?

For most applications yes — after board-level inspection, capacitor replacement where needed and a full run-in test, a refurbished drive typically delivers years of service. For safety-critical loops we recommend new.
