五、安装防呆要点
G3/8 为直管螺纹，不可强行拧入 Rc3/8 锥牙，必须加装四氟平垫圈；
剧烈水锤工况，前端加装压力表缓冲阻尼器；
充油压力表优先直立安装，横向安装会小幅改变油位，影响减震效果；
黄铜普通接头不可替代 SUS316 接头，腐蚀介质下极易渗漏。

3. Key Product Features
AU liquid-filled shock-resistant version, suitable for pulsating pressure from oil pumps, air compressors and hydraulic power units to keep the pointer stable without fluttering.
All SUS316 wetted components resist seawater, weak acid, weak alkali and corrosive hydraulic fluids.
Original Japanese factory metering accuracy with JQA inspection mark; OEM instrument for hydraulic equipment.
Direct radial mounting without bracket, simply screwed into piping or valve manifolds for easy and firm installation.
4. Application Scenarios
Pressure monitoring for hydraulic power stations and high-pressure hand pumps
Seawater hydraulic systems and stainless steel pure water pipelines
Corrosive pipelines of air compressors, chillers and water treatment facilities
Pressure measurement under vibrating conditions on construction machinery and test benches

5. Installation Guidelines & Precautions
G3/8 is a parallel thread. Do not force it into Rc3/8 taper thread; a PTFE flat washer must be fitted.
A pressure snubber shall be installed upstream under severe water hammer conditions.
Liquid-filled pressure gauges should preferably be mounted vertically. Horizontal mounting slightly shifts the liquid level and weakens shock absorption performance.
Brass standard sockets cannot replace SUS316 sockets; leakage will easily occur when handling corrosive media.
