Product Description
The HARBAX HOPG-60mm Oil Pressure Gauge is a precision-engineered instrument designed for accurate oil pressure monitoring in HVAC, refrigeration, and industrial systems. With a 60mm dial size and bottom connection design, it allows direct installation on oil lines for quick access and easy servicing.
Built using AISI 304 stainless steel casing and polished ring, this gauge ensures durability and corrosion resistance in demanding environments. The glycerine-filled plexiglass window enhances stability by reducing vibration effects and ensuring smooth, accurate readings.
Available in both low-pressure (0–250 psi) and high-pressure (0–550 psi) variants, this gauge supports a wide range of applications—from standard HVAC maintenance to high-load compressor systems. The phosphor bronze elastic element and brass movement mechanism ensure consistent performance and long service life.
Designed for professional HVAC technicians, it provides clear dial visibility, reliable accuracy (Class 1.6), and dependable system protection.
