MRO — MATERIALS & SUPPLIES

Industrial Lubricants & Maintenance Fluids

We help HVAC contractors, facility managers, and MRO procurement teams source lubricants, refrigeration oils, penetrating oils, and maintenance fluids for HVAC and industrial maintenance applications. Availability may vary by supplier, stock status, and product type.

What This Category Includes

Lubricants and maintenance fluids are essential for equipment longevity, friction reduction, and corrosion prevention. This category covers lubricants used in HVAC systems, electric motors, industrial equipment, and facility maintenance applications.

ⓘ Always verify lubricant compatibility with the equipment manufacturer's specifications. Using incorrect lubricant types — especially in refrigeration compressors — can cause equipment damage. Submit your equipment model number for compatibility support.

Refrigeration Oils

POE, PAG, and mineral oils for HVAC compressor lubrication. Oil type must match the refrigerant used in the system.

Electric Motor Oil

Non-detergent bearing oils for lubricating electric motor bearings and small mechanical assemblies.

Penetrating Oils

Penetrating lubricants for freeing seized fasteners, corroded fittings, and stuck mechanical components.

Silicone Lubricants

Silicone spray and grease for rubber gaskets, O-rings, and plastic components. Compatible with most elastomers.

Grease & Bearing Lubricants

General-purpose and high-temperature greases for bearing, coupling, and gear lubrication.

Food-Grade Lubricants

NSF H1-rated lubricants for food processing and commercial kitchen equipment where incidental food contact is possible.

Frequently Asked Questions

Q: What lubricants are used in HVAC maintenance?

Common HVAC lubricants include refrigeration oil (POE, PAG, mineral oil) for compressor lubrication, electric motor oil for bearing lubrication, penetrating oil for freeing seized fasteners, and silicone lubricant for rubber gaskets and O-rings.

Q: What type of oil is used in HVAC compressors?

Oil type depends on the refrigerant: POE (polyol ester) oil is used with HFC refrigerants (R-410A, R-32, R-454B); PAG oil is used in automotive AC systems; mineral oil is used with R-22. Never mix oil types — contamination can damage the compressor.

Q: Can I use WD-40 to lubricate HVAC motor bearings?

WD-40 is a water-displacing penetrant, not a long-term lubricant. For electric motor bearings, use a non-detergent electric motor oil or a bearing grease rated for the operating temperature and speed. WD-40 can wash out existing lubricant and accelerate bearing wear.

Q: What is a food-grade lubricant used for?

Food-grade lubricants (NSF H1 rated) are used in food processing facilities, commercial kitchens, and anywhere incidental food contact is possible. They are required for equipment in food service environments where standard lubricants are not permitted.
