Product Description

.NAI-LOK 1/4" Dual-Stage Pressure Regulator | 3500 psi High-Precision Gas Control for Laboratory & Analytical Systems
 

Product Description

The NAI-LOK 1/4" Dual-Stage Pressure Regulator is engineered for high-precision gas control applications where stable outlet pressure and high purity are critical. Designed for laboratory, analytical, and research systems, this dual-stage regulator delivers reliable performance even under fluctuating inlet pressures, ensuring safety and accuracy in gas delivery.

Made from corrosion-resistant 316 stainless steel, this regulator supports a maximum inlet pressure of 3500 psi and maintains consistent outlet pressure levels. The two-stage reduction design minimizes pressure droop and is ideal for controlling specialty gases including helium, hydrogen, nitrogen, and other corrosive or high-purity gases.

This regulator features a 1/4" NPT female inlet/outlet, compact body, and optional configurations with different port orientations and gauge placements, suitable for integration into high-purity gas panels and laboratory manifolds.

 


Key Features:
 
  • High Purity Design (Purity 5.0) for ultra-clean gas systems

  • Single-Stage Regulation ensures consistent outlet pressure

  • Spring-Loaded Mechanism for responsive pressure control

  • Suitable for Oxygen, Air, and Inert Gases

  • 100% Helium Leak Test for tightness and reliability

  • Cleanroom Assembled & Tested to meet ultra-high purity requirements

  • Compact body with 1/4" NPT (F) inlet and outlet ports
