Air conditioning o-rings and caps are needed when doing air conditioning repairs and not just any cap will do the job. Many different air conditioning systems on our roads today require a wide variety of air conditioning o-rings and caps for different locations and different reasons. Air conditioning compressor service caps are plastic, aluminum, brass and other metals. R134 refrigerant caps may be labeled H for high side or L for low side. MEI Airsource offers Bridgeport Piedmont/Schrader Bridgeport caps fit on ports of the same name and are frequently used on GM and Ford vehicles. Eaton OEM port caps are found on many Heavy Duty trucks and equipment as well as Ford vehicles. Aeroquip OEM port caps are frequently found on Chrysler, Ford heavy duty, IHC, John Deere and some GM and numerous import vehicles.
Air conditioning O-rings are available from MEI Airsource, AC Delco and Motorcraft for many vehicles. Freightliner Stat Seal, Ford Garter spring and Teflon Rotalock are examples of different names applied to different o-ring sealing technologies. GM, Ford, Sanden and Seltec compressors require different o-ring seals. MEI Airsource can meet all your air conditioning o-ring needs with o-ring assortments or in bulk packages for refilling the kits.
