HARRIS REG 821 PRESET ARG CYL PRESSURE REG FITTED W 30LPM FL

Precision argon gas control for MIG, TIG and purging applications

The Harris 821Z027 is a preset single-stage argon pressure regulator fitted with a single 0–30LPM flowmeter, purpose-built for welders who need consistent, accurate shielding gas delivery. Trusted by professional fabricators and hobbyist welders alike, this regulator combines Harris's proven high-pressure seat design with precise needle-valve flow adjustment for smooth, stable gas flow throughout your weld.

Key Features

• Preset outlet pressure (0–400kPa) – delivers a consistent, factory-calibrated pressure for reliable argon shielding gas supply
• Single 0–30LPM flowmeter – precise, easy-to-read flow tube for accurate gas flow control on MIG, TIG and gas-purging jobs
• High-pressure inlet gauge (0–24,000kPa) – clearly displays remaining cylinder pressure at a glance
• 5/8" UNF outlet thread – Australian/NZ standard thread, compatible with standard argon hoses and fittings
• Tamper-proof, self-reseating safety relief valve – built-in protection against over-pressurisation
• Type 10 bottle connection – fits standard argon cylinders (rear/side inlet configuration)
• Durable brass body construction – engineered for long service life in workshop environments

Ideal Applications

• TIG welding shielding gas regulation
• MIG welding (argon/argon-mix shielding gas)
• Gas purging for stainless steel and exotic metal welding
• Workshop, fabrication, and mobile welding setups

Why Choose the Harris 821 Series?

Harris regulators are built for durability and precision, offering accurate, repeatable flow control that welders depend on for clean, consistent welds. The 821Z027's preset design simplifies setup — just connect to your argon cylinder and dial in your flow rate, with no second-stage pressure adjustment required.
