What is an O-ring?
O-rings are round seals and they create a mechanical seal between objects to prevent leakage of liquids and gases.
Where are O-rings commonly used?
O-rings can be placed in gas cylinders, pumps, connectors and other appliances for use and form a tight seal. So O-rings can be used in agriculture, industry, oil and gas, food and construction.
What are O-rings made of?
Depending on the environment, pressure and temperature, O-rings are available in the following materials: polyurethane, neoprene, silicone, Buna-N, PTFE, etc.
Which material is best for O-ring?
There is no one “perfect” option for O-rings. Because when selecting O-rings, factors such as temperature, pH, humidity, pressure, quality, and quantity are taken into account, different O-rings have to be adapted to different needs.
What is the difference between seal and O-ring?
A gasket is a general term for a seal used to form a seal on the surface of an object, which exists in different shapes and materials, while an O-ring is a round seal with a certain degree of elasticity.
What are the advantages of O-rings?
O-rings can stop foreign contaminants, can maintain lubrication between objects, are lighter in weight, easy to install and remove, resistant to abrasion, and some materials can be adapted to extreme environments.
What causes an O-ring to leak?
O-rings can leak for several reasons: incorrect installation, wrong size, excessive pressure, chemical corrosion, too high or too low temperature, etc.
How to prevent O-ring leakage?
The following measures can be taken to prevent O-ring leakage: choosing the right size and material; proper installation; choosing the right temperature and pressure; and using the appropriate material for the specific environment.
How long can O-rings last?
O-rings can last for different times under normal conditions of use. Normally, SBR, natural rubber, polyurethane, etc. can last five years; NBR, neoprene, HNBR, etc. can last fifteen years; while silicone, ethylene propylene, fluorocarbon, fluorosilicone, etc. can be used all the time.
