A/C Chemicals





Automotive air conditioning systems are vital for providing comfortable in-cabin environment. Cooling and removing humidity from the air, your air conditioner allows you and your passengers feel comfy and cool even on a stuffy August afternoon stuck in a traffic jam. To always operate smoothly, your car air conditioner requires proper maintenance as well as the use of A/C chemicals, including air conditioning oils, leak detectors, sealers, and refrigerants.

In our assortment, you will find the finest air conditioning chemicals necessary for keeping your A/C system always at its peak. Every air conditioning system massively relies on the refrigerant. This air conditioning liquid picks up heat by means of evaporating at low pressure and temperature. The level of refrigerant in your system should be checked at regular intervals and topped off or recharged if running low. Nowadays that a number of ozone-depleting refrigerants have been banned, the most commonly used type of this air conditioning fluid is the long-lasting and environmentally-friendly R-134A.

For proper air conditioning compressor operation, the refrigerant in your system should be used with specialized synthetic oils that provide better lubrication. Before purchasing air conditioning oil, check its compatibility with the refrigerant you use and pay attention to the oil’s viscosity and solubility. The most commonly used types of air conditioning lubricants are PAG (polyalkylene glycol) and Estercool oils. PAG oils feature low volatility at high temperatures, will form no residue in the system lines and are biodegradable. Estercool or ester oil is a technologically advanced lubricant that provides excellent solvency.

In case your A/C system is losing refrigerant, it is necessary to troubleshoot the system for leaking. If ignored, leaks in this system may not only cause further loss of an expensive refrigerant, but also affect the operation of the air conditioning compressor and other integral parts of the A/C system. Leaks are usually a great trouble to locate using conventional methods. A safe and easy solution to the problem is UV dye leak checking fluids. Fluorescent dyes for PAG and Estercool oil based systems allow you to locate even the smallest and most elusive leaks. They work perfectly well with all types of UV and UV / blue light lamps.
