⚡ At a Glance
- • Lubrication Quality: Fully synthetic polyalkylene glycol base, formulated for consistent lubrication
- • Best for: Technicians and workshops carrying out R134a AC repairs and seal assembly
- • Not ideal for: Systems that require oils incompatible with PAG chemistry or non-R134a refrigerants
Fluorescent, fully synthetic PAG oil, miscible with R134a refrigerant. Designed for seal wetting during assembly and for supplementing refrigerant oil during workshop refills.
Effective seal wetting, with a fluorescent PAG-based synthetic formulation
Polyalkylene glycol base ensures miscibility with R134a and the fluorescent additive aids visibility under inspection light. The formulation remains brushable for controlled application during assembly.
Properly wet seals before installation to improve sealing and reduce the chance of leaks. Brush application allows precise coverage without excess oil.
Reliable R134a compatibility, with high miscibility
Chemical composition of the PAG base is designed to mix readily with refrigerant R134a, allowing homogeneous lubrication within the system. Compatibility helps when topping up or supplementing oil during repairs.
Suitable for servicing passenger and commercial vehicle air conditioning systems that use R134a. Ensures consistent lubrication when refilling.
Workshop-friendly application, with brushable consistency
Viscosity and texture permit brush application to seals and components, promoting even distribution during assembly. Use a brush to wet seals thoroughly prior to installation.
Controlled application reduces waste and prevents over-lubrication, making assembly quicker and more reliable for technicians. Brush use ensures seals seat correctly.
