Product Introduction
Synthetic Gas Tank Seal Oil is a premium high-performance lubricant designed for high-pressure gas tank sealing systems.
Formulated with advanced synthetic base oil and proprietary seal additives, it complies with ISO 6743-10 standards and delivers exceptional sealing performance for demanding gas storage applications.
This product is compatible with anti-bubble gas tank seal oil and non-emulsifying gas tank seal oil applications, engineered to meet the strict requirements of high-pressure gas tanks in industrial and urban gas systems.
It provides superior adhesion, anti-bubble properties, and oxidation resistance, ensuring reliable gas sealing even under high pressure while protecting sealing components from wear and corrosion.

Material & Product Advantages
• Core Material: High-purity synthetic base oil (PAO + ester blend) blended with anti-bubble additives, adhesion promoters, and anti-oxidation agents. The synthetic base oil offers superior thermal stability and chemical resistance, with mechanical impurity content ≤0.003% to meet high-pressure sealing requirements.
• Key Advantages: ① Excellent anti-bubble performance prevents air entrapment in sealing systems, ensuring consistent sealing pressure and preventing gas leakage; ② Superior adhesion forms a durable lubricating film that adheres firmly to sealing surfaces, even under high-pressure conditions; ③ Strong oxidation resistance extends service life by 2-3 times compared to mineral-based seal oils, reducing maintenance costs; ④ Non-emulsifying properties resist water contamination, maintaining sealing performance in humid environments; ⑤ Wide operating temperature range (-20℃~100℃) adapts to diverse environmental conditions.
