3003516 - Harris 3500 Series High Pressure Regulator CGA 680 0-200 PSI

Harris Model 3500-200-680 High Pressure Regulator

The Harris Model 3500-200-680 is a premium single-stage regulator designed specifically for high-pressure and high-flow applications involving inert gases. Engineered by the Harris Products Group, this regulator is part of the renowned 3500 series, known for its robust construction and reliability in heavy-duty industrial environments. The defining feature of this specific model is its CGA 680 inlet connection, which allows it to safely interface with high-pressure cylinders containing Argon, Nitrogen, or Helium at pressures up to 5500 PSIG.

Reliability is at the core of the Model 3500's design. It features a one-piece encapsulated seat with an internal filter made from PTFE Teflon. This advanced seat design not only protects the regulator from particulate contamination—a common cause of regulator failure—but also ensures a positive shut-off and extended service life. The large 2.75-inch neoprene diaphragm provides excellent sensitivity and pressure control, maintaining a steady delivery pressure of 0-200 PSIG even as the cylinder pressure decays.

Safety and durability are paramount in high-pressure gas handling. The body and bonnet are forged from solid brass, providing exceptional strength and resistance to workplace abuse. The regulator is equipped with dual-scale 2.5-inch brass gauges that are easy to read and resistant to damage. Whether used for laser cutting assist gases, heavy industrial purging, or pressure testing, the Harris 3500-200-680 delivers the performance professionals demand. It comes backed by Harris's industry-leading 7-year warranty, ensuring peace of mind for your critical operations.
