3000165 - Harris Model 301-15-200 MC Acetylene Regulator CGA 200

Technical Precision in a Compact Package

The Harris Model 301-15-200 Single-Stage Pressure Regulator is engineered to provide professional-grade performance in a compact form factor, specifically designed for "MC" style acetylene cylinders. With the internal SKU HAR3000161, this regulator represents the gold standard for light-to-medium duty applications where portability is paramount but reliability cannot be compromised. The unit features a robust brass body and a brass-painted zinc bonnet, ensuring longevity even in demanding job site environments.

At the heart of the Model 301 is Harris's proprietary one-piece encapsulated seat design. This advanced engineering integrates an internal filter that actively protects the PTFE Teflon® seat from particulate contamination, a common cause of regulator failure. Coupled with a neoprene diaphragm, the regulator delivers precise pressure control up to 15 PSIG, the safe limit for acetylene usage. The CGA 200 inlet connection is precision-machined to fit standard MC tank valves (right-hand female threads), while the outlet offers a standard 9/16" - 18 LH connection for hose compatibility.

Safety and compliance are built-in, with the device being UL® listed and backed by an industry-leading 7-year warranty. The dual 2-inch steel gauges provide clear readings for both cylinder contents and delivery pressure, allowing operators to monitor gas supply and output with a quick glance. Whether for HVAC installations, plumbing repairs, or general maintenance, the Harris 301-15-200 delivers consistent flow and pressure regulation in a lightweight, rugged package made in the USA.
