3003541 - Harris 3500 Series High Flow Nitrogen Regulator, 0-600 PSIG Delivery, CGA 580

Reliable Nitrogen Control for the Pro

When you're out in the field pressure testing an AC system or purging lines in a fabrication shop, you need a regulator that doesn't quit. The Harris 3500 High Flow Nitrogen Regulator is built for the welder and HVAC technician who demands performance. With a delivery pressure range of 0-600 PSIG, this regulator gives you the power you need to locate leaks quickly or push high volumes of nitrogen for purging applications. It connects directly to standard nitrogen tanks via a CGA 580 connection, making it a plug-and-play solution for your industrial gas needs.

Built Tough for the Job Site

Forget about flimsy regulators that crack or lose accuracy after a few months in the truck. The Harris 3500 features a solid forged brass body and bonnet. It feels heavy in the hand because it's built with quality materials meant to survive drops, bumps, and the grime of the workshop. The large adjustment knob is easy to turn, even when you're wearing work gloves, allowing you to dial in the exact pressure you need without fighting the equipment. The gauges are protected and easy to read, so you always know exactly how much gas you have left and what you're pushing into the line.

Why Choose the Harris 3500?

The secret to this regulator's longevity is inside. It uses a one-piece encapsulated seat with a built-in filter. This smart design stops dirt, metal shavings, and scale from the tank from getting into the critical seating area. This means fewer leaks, less creep, and a regulator that holds its set pressure steady. The large neoprene diaphragm reacts quickly to changes in flow, ensuring that when you open your valve, you get a steady stream of nitrogen without massive pressure drops. It also includes a tamper-proof safety valve for peace of mind when working with high-pressure cylinders.

Versatile Applications

This isn't just for welding support. It's a versatile tool for:

• HVAC/R: Perfect for pressure testing refrigeration lines and purging copper pipes during brazing to prevent oxidation.
• Industrial Maintenance: Ideal for blowing out debris from machinery or charging accumulators.
• Fabrication: Excellent for back-purging stainless steel welds to ensure a clean, sugar-free root pass.
