1973 RIDGID 535 Pipe Threading Machine

This vintage 1973 RIDGID 535 is a definitive shop workhorse, representing the era of all-metal industrial construction. Unlike modern portable units, this stationary platform is engineered for continuous, high-volume production with a focus on stability and cooling. Manufactured during a period known for robust motor windings and heavy-duty gear housings, this RIDGID 535 is built to provide decades of reliable service.

The machine features a built-in automatic oiling system with a massive reservoir, ensuring your dies stay cool and lubricated for clean, precise threads every time. Whether you are threading black iron, galvanized, or stainless steel pipe, the high-torque 36 RPM motor delivers the consistent power required for professional-grade results.
