TSI Supercool PAG 46 Refrigeration Oil with UV Dye, 32 oz Bottles — 6-Pack, Anti-Wear & Anti-Oxidant

TSI Supercool P46-32D-6CP is a synthetic PAG 46 refrigeration lubricant with UV dye, supplied as six 32-ounce bottles for R134a automotive and HVAC compressors.

This high-performance lubricant is engineered for R134a systems where a 46-viscosity PAG oil is specified. Formulated to resist moisture uptake and to include anti-wear and anti-oxidant additives, it helps maintain compressor efficiency and reduce deposit formation. The integrated UV dye enables fast leak detection with compatible inspection lights, and the case packaging is convenient for professional shops or fleet maintenance programs.

How does this oil protect my R134a compressor?

The oil combines anti-wear agents and friction modifiers to reduce metal-to-metal contact inside compressors, lowering wear rates and improving mechanical efficiency. Anti-oxidants help prevent sludge and varnish that can hinder moving parts and valves. Together these additives help the compressor run cleaner and longer under normal operating conditions.

• 46 viscosity matched for common R134a systems
• Anti-wear chemistry reduces component wear
• Anti-oxidants limit sludge and deposit formation
• Improves compressor operational efficiency

Why does the product include UV dye and how is it used?

The built-in U/V dye allows technicians to locate refrigerant leaks quickly when scanned with a compatible UV inspection lamp, saving diagnostic time. The dye is formulated to disperse evenly throughout the system with the oil and refrigerant, making small leaks visible at joints, hoses, and fittings. Use standard UV inspection procedures for safe and effective leak detection.

• Integrated dye alerts technicians to leaks under UV light
• Dye disperses with oil and refrigerant for thorough coverage
• Simplifies pinpointing seals, joints, and hose failures
• Useful for preventive maintenance and repairs

Is this oil compatible with OEM and aftermarket systems?

TSI Supercool P46 is designed to meet or exceed common OEM performance specifications for PAG 46 lubricants and is top-off compatible with equivalent aftermarket oils. It is intended for systems where a PAG 46 lubricant is specified, especially R134a mobile and stationary A/C units. Always confirm compatibility with the vehicle or equipment manufacturer before mixing different base oils.

• Formulated to meet common OEM PAG 46 standards
• Top-off compatible with equivalent PAG 46 oils
• Recommended for R134a-equipped compressors when PAG 46 is specified
• Check OEM guidance before cross-application

How should I store and handle these 32-ounce bottles?

Bottles should be kept sealed and stored upright in a cool, dry area away from direct sunlight to preserve additive stability and dye integrity. Avoid prolonged exposure to moisture and contaminants, and use proper funnels or dispensing equipment to minimize contamination when topping off systems. Dispose of or recycle empty containers following local regulations for used automotive fluids.

• Store upright in cool, dry, shaded area
• Keep caps tightly closed to avoid moisture ingress
• Use clean dispensing tools to prevent contamination
• Follow local disposal rules for empty containers

Who is this for? TSI Supercool P46-32D-6CP is aimed at automotive technicians, HVAC service shops, fleet maintenance teams, and knowledgeable DIYers who require a reliable 46-viscosity PAG oil for R134a systems with the added benefit of UV-dye-assisted leak detection. The six-bottle case suits regular service cycles, multi-vehicle shops, or anyone preferring bulk purchase for consistent product quality across jobs. Always follow manufacturer service instructions and safety procedures when handling refrigerant oils and performing A/C maintenance.
