Automotive A/C O-Ring Kit

Some years ago, for environmental reasons, the U.S. government joined a global consortium mandating the replacement of all CFC type refrigerants in favor of those with lower ozone depleting properties. This new requirement was the basis for the introduction of the R-134a refrigerant into the automotive industry. 

RT/Dygert offers a 200 piece assortment of O-rings, in the 12 most popular automotive A/C sizes.  The material used to produce this kit, is a green colored, highly saturated nitrile or HNBR.  HNBR offers excellent resistance to R-134a refrigerant, elevated operating temperatures, as well as resistance to the synthetic oils used as lubrication within the compressor.  

Material: 70 durometer green HNBR (highly saturated nitrile)
