OVERVIEW

Precision Engineering for High Purity Applications

The Harris HP721C High Purity Gas Regulator is a single-stage cylinder regulator meticulously engineered for applications requiring gas purity levels of Grade 5.0 (99.999%) and higher. Designed to meet the stringent demands of laboratory and research environments, this regulator features a 316L stainless steel diaphragm. Unlike elastomeric diaphragms, the stainless steel construction eliminates the risk of contamination from diffusion or outgassing, ensuring the integrity of your process gases remains uncompromised.

Constructed from chrome-plated brass barstock, the body of the HP721C offers a smooth internal surface finish that minimizes particle generation and entrapment. This makes it an ideal choice for non-corrosive high-purity gases such as Argon, Nitrogen, and Helium. The regulator is equipped with a CGA 580 inlet and delivers a precise pressure range of 0-125 PSIG, making it suitable for a wide array of instrumentation and analytical needs. The outlet is fitted with a 1/4" tube fitting, allowing for direct and secure connection to standard laboratory tubing systems.

Performance is paramount in the HP721 series. It utilizes a one-piece encapsulated seat design with an internal 10-micron sintered filter to protect the seating surface from particulate contamination, thereby extending the service life of the unit. The regulator also features an external relief valve to protect downstream equipment from over-pressurization. With a regulation characteristic of 1.8 psig / 100 psig, it provides stable pressure control even as cylinder pressure decays.

FAQ

The Harris HP721C is recommended for gas purity levels of Grade 5.0 (99.999%) and higher.

It features a 316L stainless steel diaphragm to prevent contamination from diffusion or outgassing.

No, the HP721C has a chrome-plated brass body. For corrosive gases, you should use a regulator with a stainless steel body, such as the Harris HP741 series.

This regulator has a CGA 580 inlet, which is standard for inert gases like Argon, Nitrogen, and Helium.

It comes equipped with a 1/4" tube fitting (compression style) for connecting to tubing lines.

The regulator can be adjusted to deliver pressures between 0 and 125 PSIG.

Yes, Harris covers this regulator with a 7-year warranty against manufacturing defects.

The maximum rated inlet pressure for this model is 3000 PSIG.
