3GS Oil

Introduction
As Oman’s leading AC spare parts supplier, Rubo Al Hail International Enterprise L.L.C., Muscat offers premium 3GS oil formulated for use with traditional refrigerants such as R12, R22 and other chlorinated compounds. Used widely in older air-conditioning and refrigeration systems, 3GS oil provides the required lubrication properties to maintain compressor integrity and extend system life.

For technicians servicing legacy systems in Muscat or across Oman—where R22-based systems are still in operation—using the correct mineral oil like 3GS ensures safe and efficient operation. We stock 3GS oil in multiple volumes suitable for both commercial contractors and retail service centres.

What It Does in HVAC Systems
3GS oil is a naphthenic mineral oil lubricant used in HVAC and refrigeration systems running on chlorofluorocarbon (CFC) or hydrochlorofluorocarbon (HCFC) refrigerants. Its primary role is to lubricate moving compressor parts, reduce friction and wear, support heat dissipation, and form a seal between piston rings and cylinder walls in reciprocating compressors.

When used with refrigerants like R22 or R12, 3GS oil mixes well and circulates throughout the system, returning via the refrigerant path to the compressor without separating. It is particularly effective in low- and medium-pressure systems where mineral oil’s natural viscosity and film strength prevent mechanical damage.

Detailed Specifications & Technical Insights
Rubo Al Hail supplies high-purity 3GS oil with properties tailored for the demanding climate of Oman. Features include:

• Viscosity index suited for high ambient temperature use
• Low pour point for improved flow in cooler conditions
• High chemical stability against refrigerant breakdown
• Moisture content below recommended limits to avoid acid formation
• Suitable for hermetic, semi-hermetic and open-type compressors

Commonly used in refrigerators, air conditioners, chillers and cold storage systems still using R22 or compatible retrofits, this oil supports long service intervals and reduces internal corrosion or oil degradation when correctly charged and managed.

Bulk Supply, Stock Confidence & Wholesale Pricing
As Muscat’s trusted HVAC parts wholesaler, Rubo Al Hail provides 3GS oil in both litre and gallon packaging, ready for bulk orders. For technicians servicing older building systems, food storage, or industrial cooling plants in Oman, having 3GS in stock ensures uninterrupted service for legacy equipment.

Benefits include:

• Local stock reduces downtime
• Cost-effective wholesale pricing
• Support for full-system oil change or top-ups
• Consistent quality across multiple containers

Our clients include facilities maintenance companies, air-conditioning specialists, and OEM repair workshops across Muscat and Oman.
