OVERVIEW

Heavy-Duty Control: Harris Model 702 Two-Stage Regulator

Upgrade your gas equipment with the Harris HP-702-250-580, a top-tier two-stage regulator engineered for consistent performance in the most demanding environments. Unlike single-stage regulators that show a "decay" or rise in delivery pressure as the cylinder empties, this two-stage model reduces the cylinder pressure in two steps. This results in a rock-steady output pressure from a full cylinder down to an empty one, providing welders and technicians with unwavering control over their gas flow.

The Model 702 is a workhorse in the Harris lineup. It features a robust forged brass body capable of handling inlet pressures up to 3000 PSIG. The 2.5-inch dual-scale gauges are easy to read, allowing for quick monitoring of both cylinder contents and delivery pressure. This specific configuration comes with a CGA 580 inlet, suitable for inert gases like Nitrogen, Argon, and Helium, and offers a substantial delivery pressure range of 0-250 PSIG. This higher output range makes it an excellent choice for applications requiring more force than standard welding regulators provide, such as blowing out lines or pressurizing systems.

Harris has equipped this unit with their time-tested encapsulated seat design, which simplifies maintenance and enhances durability. The tamper-proof, self-reseating internal safety relief valve adds an extra layer of protection for the operator. Backed by Harris's reputation for quality manufacturing in the USA, the HP-702-250-580 is the reliable choice for serious welders and tradespeople looking for equipment that lasts.

Features & Benefits

  • Constant Delivery: Two-stage reduction ensures output pressure remains stable as the tank drains.
  • High Pressure Output: Capable of delivering up to 250 PSIG for specialized tasks.
  • Rugged Build: Forged brass body and bonnet resist damage and corrosion.
  • Clean Operation: Internal filter protects the seat from debris and extends regulator life.
  • Versatile Compatibility: Fits all standard CGA 580 inert gas cylinders.

FAQ

A two-stage regulator, like the Harris 702, reduces cylinder pressure in two steps, providing a constant delivery pressure regardless of changes in the cylinder's inlet pressure. A single-stage regulator may require manual adjustment as the cylinder empties.

The CGA 580 connection is the standard fitting for inert gases. This includes Argon, Nitrogen, and Helium. It is not compatible with flammable gases or oxygen.

The Harris HP-702-250-580 has a maximum delivery pressure of 250 PSIG.

Yes, with a delivery pressure up to 250 PSIG and compatibility with Nitrogen (CGA 580), it is excellent for purging and pressure testing HVAC lines.

Yes, Harris typically offers a 7-year warranty on their heavy-duty industrial regulators, covering defects in material and workmanship.

No, this regulator is equipped with a CGA 580 inlet for inert gases. Oxygen cylinders use a CGA 540 connection. Never use oil or adaptors to force a connection to an oxygen cylinder.

The Harris 702 series features a heavy-duty forged brass body and bonnet for high durability.

Yes, it comes with two 2.5-inch brass gauges: one for reading the cylinder pressure and one for the delivery pressure.
