History and Background
Phillips Industries began in 1928 as a Los Angeles vehicle-parts business founded by H.W. Phillips. An early invention was a reflective directional signal arm for trucks, which helped establish the company’s manufacturing business.
The company expanded into electrical connections, producing a practical coiled seven-way electrical assembly in 1974. STA-DRY products followed in the 1980s to address moisture intrusion and corrosion at electrical connections.
Phillips remains family-owned and operated. Its development has continued through quick-change connectors, trailer wiring systems, and related commercial-vehicle equipment.

Technology and Product Development
Phillips’ connection products address common service problems involving moisture, corrosion, cable damage, and worn electrical contacts. STA-DRY equipment and quick-change designs are central parts of this approach.
Its broader catalog includes tractor-to-trailer cable assemblies, trailer wiring equipment, liftgate charging connections, and pneumatic connections. These components work together to carry electrical power and compressed air between commercial vehicles and their trailers.
Phillips also established Phillips Connect in 2017 to develop connected-vehicle technology. Phillips Industries’ physical connection equipment and Phillips Connect’s telematics products serve related functions within the wider truck-and-trailer system.
