Oxygen O-Rings

Oxygen is a colorless, odorless gas used in many industries, including aviation, medical, and metallurgy. The presence of oxygen can accelerate the aging of rubber materials, leading to oxidative degradation, swelling, and brittleness. Typical types of damage to rubber exposed to oxygen include loss of elasticity, decreased tensile strength and tear resistance, as well as discoloration caused by oxidation.

Oxygen O-Rings - Material Properties

Oxygen O-rings are specially designed seals in the shape of rings, known for their excellent flexibility, sealing properties, and durability. These O-rings are made from materials resistant to oxygen, ensuring high performance and longevity. Their hermetic seal effectively prevents gas leakage. Below are examples of materials that do not degrade when in contact with oxygen:

Silicone O-Rings

VMQ silicone O-rings are made from a synthetic material based on silicon, oxygen, and other elements such as hydrogen and carbon. This combination gives silicone excellent flexibility.
This elastomer material has excellent resistance to both low and high temperatures (ranging from -60°C to 210°C, with short-term resistance up to 250°C) without damage or distortion. It also serves as a good electrical insulator. Due to its resistance to bacteria and fungi, it is ideal for medical, pharmaceutical, and food industries. The material is physiologically neutral, meaning it does not affect taste or odor. VMQ O-rings also show good resistance to compression, light, ozone, UV radiation, hot air, and animal and vegetable oils and fats. They come in various hardness grades. Due to their relatively low physical strength (low resistance to tearing and abrasion), they are commonly used as static seals.

EPDM O-Rings

EPDM sealing rings are resistant to heat, oxidation, and aging from ultraviolet light. The material offers good mechanical properties (abrasion resistance, tensile strength). It remains flexible at low temperatures and is chemically resistant when in contact with acids and bases. It has low water absorption and good insulating properties. EPDM O-rings are resistant to oxygen, ozone, steam, and hot water.

Neoprene O-Rings

This elastomer material is highly water-resistant and offers excellent resistance to oxidative UV light and weather conditions. It is compatible with fats, oils, and petroleum-based chemicals. CR sealing rings can be used in a wide and variable temperature range. They are resistant to fire and damage caused by bending and twisting. They effectively prevent the escape and penetration of liquids and gases into applications. Neoprene O-rings are characterized by high flexibility and durability.

FKM/FPM/Viton® O-Rings

Fluoroelastomer sealing rings show exceptional resistance to aggressive chemicals, oils, and extreme temperatures. Viton® material is preferred due to its compatibility with oxygen. It has low gas permeability and excellent aging properties (it retains its original flexibility and strength). FKM O-rings are resistant to ozone, weather conditions, synthetic hydraulic fluids, mineral oils, high vacuum, silicone greases, fuels, aromatic compounds, and many organic solvents.

O-Rings for Liquid Oxygen (LOX)

For sealing liquid oxygen, materials resistant to extremely low temperatures are used, such as PTFE O-rings and FFKM O-rings.
