Harris Model 301 Acetylene Regulator for B-Tanks, CGA 520, 15 PSIG

Harris Model 301-15-520 Acetylene Regulator Overview

The Harris Model 301-15-520 is a premium single-stage acetylene regulator designed specifically for light to medium-duty applications. Engineered for professionals who demand reliability and precision, this regulator is tailored to fit "B" style acetylene cylinders, which are commonly utilized in the plumbing and HVAC industries. With a storage capacity of approximately 40 cubic feet, B-tanks require a specific CGA 520 inlet connection, which this model provides with a right-hand female thread configuration.

At the core of the Model 301's performance is its robust construction. The body is machined from solid brass, offering exceptional resistance to corrosion and the wear-and-tear typical of job site environments. Internally, the regulator features Harris's proprietary one-piece encapsulated seat design. This advanced engineering integrates an internal filter and a PTFE Teflon® seat, which significantly protects the critical sealing components from particulate contamination. This design choice not only extends the service life of the regulator but also ensures consistent pressure delivery over time.

Safety and accuracy are paramount when handling acetylene. The Harris 301-15-520 is calibrated to provide accurate pressure regulation up to 15 PSIG, adhering to standard safety protocols for acetylene gas. The unit is equipped with dual 2-inch steel gauges that provide clear readings of both cylinder contents and delivery pressure. Weighing in as a compact and lightweight unit, it does not sacrifice durability for portability. This model is UL listed, Made in the USA, and comes backed by an impressive 7-year factory warranty, underscoring Harris's commitment to quality manufacturing.

Whether you are performing silver brazing on copper pipes or light welding repairs, the Harris 301-15-520 ensures a stable flame and reliable gas flow. Its 9/16" - 18 outlet connection is compatible with standard acetylene hoses, making it a seamless addition to your existing oxy-fuel outfit.
