Introduction
Rubo Al Hail International Enterprise L.L.C., based in Muscat, Oman, offers top-grade 4GS mineral refrigerant oil for high-performance HVAC and refrigeration systems using CFC and HCFC refrigerants. As an AC spare parts supplier in Muscat with a legacy of over four decades, we cater to HVAC professionals seeking reliable lubrication solutions for compressors operating in extreme temperature and pressure conditions.
With Oman’s challenging climate, selecting the right oil is essential for maintaining system performance, protecting compressors, and ensuring operational longevity. Our 4GS oil meets these demands with enhanced viscosity and stability suited to high-load applications.
What It Does in HVAC Systems
4GS oil is used in refrigeration and air-conditioning systems that operate with refrigerants like R22, R12, and R502. This lubricant supports internal compressor operation by reducing mechanical wear, maintaining seal integrity, and aiding in heat transfer from the compressor’s moving parts.
In Oman’s commercial cooling applications—from cold rooms to rooftop AC units—4GS oil provides the high film strength and thermal resilience needed to prevent overheating and oil breakdown. It is particularly effective in large reciprocating compressors, rotary units, and systems that run for extended hours or experience frequent start-stops under load.
Detailed Specifications & Technical Insights
Rubo Al Hail’s 4GS oil is manufactured to meet or exceed OEM requirements and industry standards. Key specifications include:
- Mineral oil base (naphthenic) with a viscosity index suited for high-stress systems
- Moisture content controlled below acceptable limits to prevent chemical reactions
- Excellent miscibility with CFC and HCFC refrigerants
- High dielectric strength for use in hermetic motors
- Low wax content for minimal deposit formation and better fluidity in variable temperatures
Our 4GS oil is available in quart, gallon, and drum formats to serve both retail and wholesale requirements. It is recommended for use in equipment made by leading global compressor manufacturers such as Bitzer, Copeland, Tecumseh, and Carrier.
