TSI Supercool PAG Compressor Oil for R134a — 46 Viscosity, 32 oz with UV Dye for Leak Detection

TSI Supercool P46-32D is a 46-viscosity synthetic PAG compressor oil formulated for R134a air conditioning systems, featuring UV dye for leak detection and additives to protect and prolong compressor life.

This 32-ounce bottle of TSI Supercool P46-32D supplies a purpose-built lubricant engineered for modern mobile and stationary R134a A/C systems. Designed to resist moisture, inhibit oxidation, and reduce wear, the formula balances viscosity and protective additives so compressors run smoothly and A/C performance remains consistent. The built-in U/V dye helps technicians locate leaks quickly during service, simplifying diagnostics without altering system chemistry.

How does this oil protect A/C compressors?

TSI Supercool P46-32D contains anti-wear agents and friction modifiers that form protective films on moving parts, reducing metal-on-metal contact and slowing component wear. Anti-oxidants minimize sludge and deposit formation, helping maintain clear passages and consistent lubrication over time.

• Anti-wear additives reduce compressor surface scuffing and extend service life
• Friction modifiers improve mechanical efficiency and reduce operating loads
• Anti-oxidants limit sludge and varnish build-up inside the system

Will this oil work with my R134a system?

This PAG oil is specifically formulated for R134a refrigerant systems and meets common OEM performance expectations for such applications. Confirm compatibility by checking your vehicle or equipment manufacturer's lubricant recommendations and ensuring the use of PAG oil for R134a systems.

• Made for R134a refrigerant applications where PAG oil is specified
• 46 viscosity rating suitable for many standard compressor designs
• Follow OEM guidance for oil type and quantity when servicing

Why is the UV dye useful and how should it be used?

The integrated U/V dye allows technicians to locate refrigerant leaks quickly by illuminating dye under ultraviolet light. Use standard A/C UV inspection tools after charging or during a service check to pinpoint leak sites without invasive disassembly.

• Dye is pre-blended for immediate leak detection with UV lamps
• Helps identify hard-to-see leaks in hoses, fittings, and evaporators
• Reduces diagnostic time and helps plan targeted repairs

How does viscosity affect system performance?

The 46 centistoke viscosity rating offers a balance between film strength and flow characteristics at operating temperature, ensuring the oil circulates properly while maintaining protective film on bearings and other moving parts. Choosing the correct viscosity helps prevent inadequate lubrication or excessive drag in the compressor.

• 46 viscosity provides robust film protection at typical A/C temperatures
• Supports efficient oil return through system lines and components
• Helps stabilize lubrication across varied operating conditions

Who is this for: Technicians and DIY enthusiasts who service R134a air conditioning systems and need a reliable, OEM-grade synthetic PAG oil with UV dye for leak detection. Ideal for automotive, light commercial, and HVAC service applications where a 46-viscosity PAG is specified and technicians want faster diagnostics and long-term protection against wear and deposits.
