3200326 - Harris HP 8700 High Pressure Regulator 0-3000 PSIG CGA 680

Precision High-Pressure Control with Harris Model 8700

The Harris Model 8700-3000-680 is a premium single-stage regulator engineered specifically for high-pressure applications where reliability and safety are paramount. Designed to operate on ultra-high-pressure cylinders, this regulator is a staple in industries requiring precise gas delivery for testing, charging, and pressurization tasks. The unit is built around a robust body and bonnet machined from solid brass bar stock, a construction method that offers significantly higher strength and durability compared to forged alternatives. This heavy-duty design ensures the regulator can withstand the rigors of industrial environments while maintaining structural integrity under high inlet pressures.

At the core of the Model 8700's performance is its advanced seating technology. It utilizes a one-piece encapsulated seat design featuring a CTFE (Kel-F) sealing element. CTFE is chosen for its exceptional resistance to deformation and chemical attack, making it the ideal material for high-pressure gas regulation. The encapsulated design also includes an internal filter that protects the seat from particulate contamination, a common cause of regulator failure in field conditions. This attention to internal geometry ensures a long service life and consistent performance, even when handling high-velocity gas flows associated with 3000 PSIG delivery.

Operational ease is enhanced by the ergonomic adjustment knob, which provides smooth torque for precise pressure settings. The regulator is equipped with dual-scale brass gauges (PSIG and BAR), allowing operators to monitor cylinder and delivery pressure at a glance. The outlet is fitted with a 1/4" NPT connection and comes standard with a stainless steel 1/4" tube fitting, making it ready for immediate connection to high-pressure hoses or hard lines used in hydraulic accumulator charging or aircraft strut maintenance. With a CGA 680 inlet, this model is specifically configured for high-pressure inert gas cylinders, typically Nitrogen or Argon, up to 5500 PSIG.
