YamamotoKeiki AU-G1/4-φ60×1MPa All-Stainless Steel Pressure Gauge (SUS316)

YamamotoKeiki AU-G1/4-φ60×1MPa is an all-stainless steel, glycerin-filled anti-vibration and corrosion-resistant pressure gauge belonging to YamamotoKeiki’s AU-G series. Its wetted parts are made of SUS316 stainless steel, specially designed for environments requiring both corrosion resistance and vibration resistance. It strictly complies with JIS B 7505 industrial standards and is manufactured in Japan. Combining corrosion resistance, anti-vibration performance and compact size, it meets low-pressure monitoring requirements in various compact installation scenarios.

I. Complete Model Interpretation

Each code in the model corresponds to a clear specification, serving as key reference for model selection and installation. Details are as follows:

A: Indicates Type A (vertical, bezel-less), radial mounting (bottom connection), suitable for standard radial installation.
U: Indicates a U-shaped wrench flat at the thread base (two flat surfaces).
G1/4: Connection thread specification: G1/4 (PF1/4 parallel thread), matching the standard thread configuration for YamamotoKeiki φ60 pressure gauges and compatible with most small-to-medium industrial equipment.
φ60: Dial diameter: 60 mm, a compact, lightweight design ideal for equipment or integrated units with limited installation space.
1MPa: Measuring range: 0–1.0 MPa, a low-pressure range suitable for pressure monitoring in various low-pressure fluid systems.
Implied specifications: Wetted parts (bourdon tube, connection) are SUS316 stainless steel; case and bezel are SUS304 stainless steel. As the core configuration of the all-stainless steel corrosion-resistant design, SUS316 provides excellent corrosion resistance against weak acids, alkalis, seawater and corrosive industrial atmospheres.

II. Core Technical Parameters (Compliant with JIS B 7505-1)

Item	Specification
Accuracy Class	±1.6% F.S. (full scale), meeting industrial Class 2 accuracy for general production pressure monitoring.
Dial Size	φ60 mm (compact dial), with clear graduations for easy reading and space-saving installation.
Mounting Style	Type A (vertical, bezel-less), radial mounting (bottom connection).
Connection Thread	G1/4 (PF1/4 parallel thread), matched to φ60 dial for small-to-medium equipment.
Wetted Materials	Bourdon tube & connection: SUS316 stainless steel, resistant to acids, alkalis, seawater and salt spray, superior to SUS304 for corrosive industrial environments.
Case & Bezel	SUS304 stainless steel (all-stainless steel structure), paint-free, rust-resistant and highly durable against atmospheric corrosion.
Lens	Safety glass with high light transmittance, effectively protecting internal components and preventing breakage.
Operating Temperature	-5℃ ~ +55℃ (glycerin-filled range); temperatures outside this range may affect accuracy or glycerin performance.
Protection Level	Dustproof and splash-proof (rain-resistant), suitable for harsh workshop conditions such as humidity and dust to prevent internal rust.
Suitable Media	Weakly corrosive gases and liquids (e.g., oil, water, general chemicals), non-crystallizing and non-coagulating media.
Overload Capacity	Short-term overload not exceeding 120% F.S. (≤1.2 MPa); long-term use must stay within range to avoid movement damage.

III. Core Product Features

1. Dual Core: All-Stainless Steel Corrosion Resistance + Glycerin Anti-Vibration

With an all-stainless steel structure, the SUS316 wetted parts deliver outstanding corrosion resistance against weak acids, alkalis, seawater and salt spray, with good heat resistance and weldability for harsh industrial environments. Glycerin filling absorbs equipment vibration and pressure pulsation, stabilizes the pointer, reduces internal wear, prevents pointer drift due to pressure shock, isolates external corrosive media, and extends service life — ideal for combined corrosive and vibrating conditions.

2. Compact Design for Limited Installation Space

At φ60 mm, the small dial is lighter and more compact than φ75 or φ100 mm gauges, making it ideal for integrated equipment, compact hydraulic/pneumatic units and small pump sets without sacrificing readability.

3. Standardized & Highly Compatible

Compliant with JIS B 7505 with ±1.6% F.S. accuracy for general industrial use. The standard G1/4 connection fits most small-to-medium industrial equipment without adapters, enabling easy installation.

4. Safe, Durable & Low-Maintenance

Safety glass lens and fully sealed case block dust and moisture. The paint-free stainless steel case resists rust and is easy to clean. The sealed glycerin design requires no frequent refilling, resulting in low daily maintenance costs.

IV. Typical Applications

Leveraging its compact size, corrosion resistance and anti-vibration performance, this gauge is widely used in low-pressure, vibrating and corrosive conditions:

Small hydraulic/pneumatic equipment: Small hydraulic units, oil pumps, air compressors, pneumatic valves for low-pressure monitoring under vibration in tight spaces.
Construction machinery / small vehicles: Hydraulic systems of mini excavators, loaders and small dump trucks, resisting vibration and outdoor mild corrosion (rain, dust).
Chemical / water treatment: Small dosing units, filters and weakly corrosive pipelines for low-pressure (≤1MPa) monitoring with resistance to weak acids and alkalis.
Food / pharmaceutical: Small food processing, brewing, pure water / sterile water systems (hygienic applications), with non-polluting all-stainless steel construction.
Marine / offshore: Small marine equipment and deck machinery systems, resisting salt spray and shipboard vibration.
General small machinery: Auxiliary hydraulic systems for machine tools, small injection molding machines, printing machinery and small compressor stations in cramped low-pressure vibrating environments.
Medical auxiliary equipment: Small medical gas systems (e.g., dental chair air circuits), saving internal space for low-pressure monitoring.

V. Selection & Usage Notes

1. Suitable Scenarios

Ideal for low pressure (0–1MPa), vibrating environments, weakly corrosive media, limited installation space, and G1/4 connections requiring both corrosion and vibration resistance.

For extended service life and accuracy:

Static pressure ≤ 75% F.S. (≤0.75 MPa)
Fluctuating pressure ≤ 66% F.S. (≤0.66 MPa)

2. Unsuitable Scenarios

Temperatures below -5℃: Glycerin may solidify and lose damping; silicone oil-filled gauges recommended.
Strongly corrosive media (high-concentration acids/alkalis): Diaphragm-type pressure gauges required to protect wetted parts.
Pressures above 1MPa: Exceeding the range damages the bourdon tube and movement; select higher-range AU-G models.
Extreme vibration or high-frequency pressure pulsation: Use higher-protection anti-vibration models to avoid excessive movement wear.

3. Usage Precautions

Ensure proper sealing during installation to prevent leakage. Avoid long-term overload. Check glycerin level regularly and refill if low. Install away from direct sunlight and high temperatures to prevent glycerin degradation and reduced anti-vibration performance.
