Located near the pressure valves of the condenser are O-rings, which help prevent leakage. Once these rings are worn, they should be replaced immediately to prevent a refrigerant leak.

Do you need special o rings for AC?
A better type of O-ring for air conditioning applications is HNBR which stands for Hydrogenated NBR (sometimes called Hydrogenated Nitrile, or Highly Saturated Nitrile Rubber, or HNB). The compatibility of HNBR with Mineral oil, PAG, POE, R-12, R-134a, R-1234yf is very good.
What is an O-ring in a car ac?
The AC Oil O-ring is a rubber/neoprene fitting that is used in your car's air-conditioning system to prevent the loss of refrigerant through leakage. The O-rings are fitted between the pressure valves of the condenser and AC hoses of the compressor. They are generally elastic, compressible and pressure-resistant.
What are the different type of o rings?
Some of the common types of O-ring materials include PTFE, Nitrile (Buna), Neoprene, EPDM Rubber and Fluorocarbon (Viton). Silicone and Kalrez® O-ring materials are also widely used, especially in high temperature applications.
What are auto AC o rings made of?
o-rings, also known as Highly Saturated Nitrile (HSN). The material is a synthetic polymer made by saturating the double bonds in nitrile=s butadiene segments with hydrogen.
Are AC O-rings oil resistant?
Good resistance to a wide variety Temperature: -15° To 400° Halogenated Hydrocarbons, Steam of chemicals. Water, Alcohol, Acetone, Petroleum Oils & Good heat resistance. Steam, Brake Fluids, Fuels, Toluene Resistant to sunlight & weathering.
What oil do I use for my AC O-ring?
Pure silicone oil used as an O-ring lubricant allows for better installation and protects the gaskets from damage. Having wrongly thought that O-rings were simple things, I've added a small container of 100 percent pure silicone oil to the toolbox.
Why are AC O-rings green?
Green o rings are hydrogenated Nitrile, also known as highly saturated Nitrile, or more commonly known as HNBR. These o rings have the green colour moulded into their rubber and were introduced with the refrigerant of 134a, suitable for high temperatures and fluctuating stress loads.
What O-ring material is best for high pressure?
O-Ring Durometer
High-durometer o-rings are better suited for higher pressures and are more resistant to extrusion. Hard material yields higher pressure required to force the o-ring into extruding. The only drawback to a high durometer is the decreased squeeze of the o-ring.
How do you choose an O-ring?
The size of an O-ring can be determined by measuring the diameters and the width of the cross-section. The measurement you will need to include are the internal diameter (ID), outside diameter (OD), and the cross-section width (CS).
What is EPDM O-ring?
EPDM o-rings, or ethylene propylene o-rings, are a family of synthetic elastomers with lower cost steam and chemical resistance, particularly for applications involving solvents, acids and other mild chemicals.
Is O ring a gasket?
O-rings are circular, ring-shaped pieces that sit in a groove between two (usually cylindrical) parts. ... Terminology note: Any o-ring can technically be called a gasket since they prevent the transfer of liquid and air, but while o-rings are a specific shape of gasket, any gasket cannot be called an o-ring.
What type of seal is an O ring?
O-ring seals are mechanical gaskets with a round cross-section. They are made from elastomer materials and used in pumps, cylinders, and other fluid applications to form a leak-proof seal between two parts.
Are all rubber o-rings the same?
Whether sold individually, in large wholesale batches or - as is increasingly common - as part of a highly flexible range of o-ring kits, the basic form and role of o-rings are generally the same across the board.
