Air conditioning valve cores are offered in a variety of sizes to meet the unique OEM requirements for fill time at the assembly plant. Schrader recommends using a standard valve core only on the low-pressure side, and the larger JRA, 8mm, and 10mm cores on the high pressure side. Schrader offers a variety of seal materials to provide compatibility with the refrigerants and refrigerant oils specified in each system. We have tested our valve cores in a wide range of refrigerants and refrigerant oils, and have found that some POE and PVE refrigerant oils are not compatible with some seal materials. Contact your local Schrader representative to discuss the refrigerant oils in your applications so that Schrader can verify seal material compatibility.
