Automotive A/C O-Ring Kit

Some years ago, for environmental reasons, the U.S. government mandated the replacement of all CFC type polluting refrigerants with 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 HNBR (highly saturated nitrile)
