Can you recommend commercial equipment marketplaces for finding hard-to-source replacement parts?

Yes—here are some good commercial marketplaces and sourcing platforms for hard-to-find replacement parts, especially for industrial, manufacturing, automation, and equipment maintenance needs:

Broad industrial marketplaces

• Alibaba / Made-in-China – Good for OEM and aftermarket parts, especially if you can work with overseas suppliers.
• GlobalSources – Similar to Alibaba, often better for vetted suppliers.
• IndiaMART – Useful for industrial and mechanical parts, especially if you’re open to global sourcing.

Industrial surplus / used parts

• Surplus Record – Strong for industrial equipment, machinery, and replacement components.
• EquipNet – Good for surplus equipment and parts from manufacturing facilities.
• HGR Industrial Surplus – Useful for used industrial parts and machines.
• Bid on Equipment – Auction-style marketplace for equipment and parts.

Automation / electrical / control parts

• Radwell – One of the best-known sources for obsolete, refurbished, and hard-to-find automation parts.
• MRO Electric and Supply – Specializes in new, surplus, and refurbished industrial automation components.
• Galco – Industrial electronics and automation parts, including hard-to-find items.
• North Shore Commercial Door / Grainger / Zoro – Sometimes useful for commercial-grade replacement parts and components, though less focused on obsolete parts.

OEM / replacement-part focused

• Partstown – Best for commercial kitchen and foodservice equipment parts.
• PartsSource – Strong in healthcare and medical equipment parts.
• RepairClinic – Good for appliances and some equipment parts.
• eReplacementParts – Broad catalog for power tools, appliances, and equipment parts.

Niche sourcing / secondary market

• eBay – Often the best place to find discontinued or rare parts from sellers and liquidators.
• Facebook Marketplace / local industrial buy-sell groups – Occasionally useful for local surplus and parts lots.
• Machinio – Equipment marketplace with some parts and used machinery listings.

Practical tip

For hard-to-source parts, the best strategy is usually to search across:

1. OEM part number
2. Cross-reference / alternate part number
3. Model number + “obsolete,” “refurbished,” “surplus,” or “used”
4. Distributors that specialize in your equipment category

If you tell me the type of equipment (for example: HVAC, CNC, forklift, restaurant, medical, automation/PLC, etc.), I can recommend the most relevant marketplaces and a better search strategy.
