3000165 - Harris Model 301 Single-Stage Acetylene Regulator, CGA 200 (MC Tank)

Harris Model 301-15-200MC Single-Stage Acetylene Regulator

The Harris Model 301-15-200MC is a premium single-stage regulator engineered specifically for light to medium-duty applications involving acetylene gas. Designed to interface seamlessly with MC-style acetylene cylinders via a CGA 200 inlet connection, this regulator is a staple in industries requiring portability without sacrificing precision. The unit is manufactured in the United States and adheres to strict quality standards, boasting a UL listing that ensures operational safety and reliability.

At the core of the Model 301's performance is its robust construction. The body is machined from solid brass, paired with a brass-painted zinc bonnet, creating a rugged exterior capable of withstanding the wear and tear of daily industrial use. Internally, the regulator features a one-piece encapsulated seat design with a PTFE Teflon® seat. This advanced seating mechanism is protected by an internal filter, which plays a critical role in preventing particulate contamination—a common cause of regulator failure. This design choice significantly extends the service life of the component, ensuring consistent performance over time.

Pressure control is managed by a high-quality neoprene diaphragm, which provides accurate regulation up to a maximum outlet pressure of 15 PSIG. This specific pressure cap is a vital safety feature for acetylene applications, preventing the unstable conditions that occur at higher pressures. The regulator is equipped with dual 2-inch steel gauges that display pressure readings in both PSI and kPa, allowing operators to monitor cylinder contents and delivery pressure with ease. The ergonomic brass "T" screw handle makes adjusting pressure settings smooth and precise, even when wearing work gloves.

Ideal for maintenance, repair, and operations (MRO) environments, the Harris 301-15-200MC combines the durability of heavy-duty equipment with the compact footprint required for mobile applications. Whether used for brazing in tight quarters or general cutting tasks, this regulator delivers the consistent flow and safety features professionals demand. It comes backed by Harris's industry-leading 7-year warranty, providing peace of mind and long-term value.
