MANIFOID GAUGE SINGLE lOW HS-466

Description

Product Description The Hongsen HS-466 NAL is a professional-grade, 1-way single low-pressure manifold gauge engineered for HVAC technicians and DIY mechanics alike. Designed specifically for low-side system testing, evacuation, and refrigerant charging, this high-precision instrument features a rugged brass body valve assembly and a highly visible, color-coded diagnostic gauge face (typically reading from -30 psi up to 500 psi). Enclosed in a shock-resistant, heavy-duty protective rubber boot, the gauge is built to withstand the rigors of daily field use. Its smooth-operating, oversized hand valve provides precise flow control, while the clear sight glass allows for real-time monitoring of refrigerant flow and state. Key Features: Multi-Refrigerant Compatibility: Features clear, easy-to-read scale rings dialed in for multiple common refrigerants. Heavy-Duty Construction: Built with a solid brass valve body and an impact-resistant rubber gauge protector. Precision Diagnostics: High-accuracy low-pressure readings (-30 inHg to 500 psi) perfect for monitoring vacuums and low-side pressures. User-Friendly Design: Includes a large, ergonomic hand knob for effortless valve adjustment. Compatible Machinery & Systems The Hongsen HS-466 NAL low-pressure gauge is highly versatile and compatible with a wide array of cooling, refrigeration, and climate control machinery that operate using standard pressure ports. 1.
