Product Advantages
1. Exceptional extreme pressure performance withstands pressures exceeding 35MPa, forming a stable lubricating film that prevents metal-to-metal contact and wear.
2. Superior thermal stability resists degradation at high temperatures (up to 150℃) generated by ultra-high pressure operation, extending oil change intervals.
3. Strong corrosion and rust resistance protects cylinder components from moisture and harsh industrial environments, even under extreme pressure conditions.
4. Excellent film durability maintains lubrication effectiveness for extended periods, reducing maintenance frequency and equipment downtime.
5. Compatible with high-pressure cylinder materials and seals, ensuring no adverse reactions or leakage issues.
Craft & Technology
This oil is made with highly refined mineral base oil and a custom high-performance additive package, using advanced blending and purification technology. We strictly control the additive ratio to enhance extreme pressure resistance and anti-wear capacity, and the multi-stage filtration process removes impurities, ensuring the oil's purity. The formula is tested repeatedly under real ultra-high pressure working conditions to make sure it meets the practical operation needs of various cylinder equipment.
