L-HL 15 / 22 / 32 / 46 / 68 / 100 / 150
Hydraulic oil with rust and oxidation inhibitors, formulated for machine tools, hydraulic headstock tanks, gearboxes, and industrial circulating lubrication systems. Provides oxidation resistance, rust protection, foam suppression, water separation, and seal compatibility. Available for wholesale supply, bulk procurement, OEM cooperation, and private label coordination.
Hydraulic oil R&O is an industrial lubricating oil with rust and oxidation protection, designed for hydraulic and circulating lubrication systems that do not require a high level of anti-wear properties. Its viscosity-temperature characteristics help maintain lubricating, cooling, and sealing capability under varying operating temperatures and system conditions.
The product provides oxidation stability, rust protection, foam suppression, air release, demulsibility, and filterability. Typical applications include hydraulic reservoirs of machine tool spindles, low-load hydraulic equipment, enclosed gearboxes, and industrial circulating lubrication systems.
MOSINTER GROUP coordinates production resources through invested manufacturing facilities, and MOSINTER GROUP supports international buyers with wholesale supply, bulk procurement, OEM and private label coordination, export documentation, and product specification alignment.
Thanks to the production resources invested and coordinated by MOSINTER GROUP, we support the manufacturing and international supply of R&O hydraulic oil for lubricant distributors, industrial equipment operators, service companies, and project procurement groups.
MOSINTER GROUP supports overseas customers in placing wholesale orders, procuring large volumes, coordinating OEM and private label production, selecting packaging, preparing export documentation, and agreeing on technical specifications. Delivery terms may be negotiated depending on viscosity grade, packaging requirements, target market, and intended application.

R&O stands for rust and oxidation inhibition. R&O hydraulic oils are designed to provide corrosion protection, oxidation resistance, foam control, water separation, and lubrication in industrial hydraulic and circulating lubrication systems.
Typically used in hydraulic reservoirs of machine tool spindles, lightly loaded hydraulic equipment, enclosed gearboxes, and industrial circulation lubrication systems that do not require a high level of anti-wear properties.
Available viscosity grades include ISO VG 15, 22, 32, 46, 68, 100, and 150. The appropriate grade should be selected according to equipment requirements, operating temperature, and system design.
Yes. MOSINTER GROUP supports international corporate buyers by providing bulk supply, large-lot procurement, OEM and private label coordination, packaging communication, and export documentation through the MOSINTER GROUP production network.
