Supco Motor & Electrical Parts & Accessories

Supco Motor & Electrical Parts & Accessories: Engineered Reliability Since 1945

Supco — formally known as Sealed Unit Parts Co., Inc. — has spent decades earning a reputation as one of the most trusted names in electrical components and motor parts. Founded in 1945 in the Bronx, NY by two naval engineers, Supco originated as a service company for refrigeration systems, and that deep, practical understanding of real-world service demands has shaped every product the brand has produced since. When it comes to Motor & Electrical Parts & Accessories, Supco brings that same field-tested mindset to every component it designs and manufactures.

A Legacy of Electrical Innovation

Supco's contributions to the electrical components space are far more than incremental — the brand has been responsible for genuine industry firsts. Supco engineers invented the patented Bullet Line Tap valve in the 1960s, discovered the PTC technology behind the company's two-wire air conditioning and refrigeration hard start kits, and manufactured the electronic vacuum gauge in the 1990s. Together with its international partner SIL, Supco was the first company in the world to introduce PTC starting relays to the HVAC industry, which is used today by all compressor manufacturers. These milestones reflect a brand that doesn't just follow the industry — it defines it.
