HGA Series 700 Bar Precision Gauge Adaptors
Engineering Overview & Structural Features
The HGA Series 700 Bar Precision Gauge Adaptors are precision-machined from solid forged alloy steel billets rated for continuous 700 Bar (10,000 PSI) working pressure with a 4:1 safety factor. Engineered for direct in-line installation between pumps, hoses, and cylinders, HGA adaptors allow instant integration of pressure monitoring instruments without restricting system fluid flow. The lineup includes 45-degree angled models for optimal ergonomic operator viewing, 90-degree vertical blocks for compact inline headers, and ultra-compact right-angle corner blocks with 1/4" and 1/2" NPT gauge ports.
700 Bar Solid Forged Steel Construction
Machined from solid forged high-tensile alloy steel billets without welds or porosity, ensuring full 700 Bar continuous rating and 2,800 Bar burst pressure integrity.
Direct In-Line Circuit Installation
Threaded with 3/8" NPT Male inlet to 3/8" NPT Female outlet for seamless insertion between pumps, hose lines, and cylinders without bulky piping adapters.
Ergonomic 45° Dial Reading Angle
Models HGA-002 and HGA-003 tilt the gauge face at a natural 45-degree angle toward the pump operator, eliminating reflection and awkward neck-bending during high-pressure lifting.
1/4" & 1/2" NPT Gauge Thread Options
Compatible with 63.5 mm (1/4" NPT) and 101.6 mm (1/2" NPT) pressure gauges, allowing users to adapt standard gauges without compounding threaded adapters.
Compact Corner Profile (HGA-006)
Engineered with an ultra-short 65 mm body length, the HGA-006 right-angle adaptor fits tightly into congested pump enclosures and manifold control stations where clearance is minimal.
Corrosion-Resistant Protective Finish
Machined forged bodies feature high-durability electroplated anti-corrosion plating that withstands outdoor marine exposure, rain, and aggressive hydraulic mineral oils.
