Rubber O-rings are essential to the field of sealing engineering. Its sealing effectiveness is closely correlated with the chosen range of its stretch amount and compression ratio. An overview of the rubber O-ring stretch amount and compression ratio option range is shown below.
What is stretch
The circle of the rubber sealing ring when it is fitted in the sealing groove is larger than when it is not, and this is referred to as the amount of stretch. It displays the amount of strain that the rubber seal experiences upon installation.
Selection range
In order to guarantee sealing performance, the selection range of the stretch amount should typically guarantee that the rubber sealing ring can conform to the shape of the sealing groove and retain the proper pressure after installation.
Generally speaking, the stretch should fall within the rubber material's permissible range to prevent the rubber sealing ring from breaking or offering insufficient sealing power.
Based on the size and composition of the rubber O-ring, the temperature, pressure, and other elements of the operating environment, the precise stretch amount selection must be carefully thought out.

What is compression ratio
When the rubber sealing ring is inserted in the sealing groove and its cross-sectional diameter is reduced from its non-installed diameter, this is referred to as the compression rate. It illustrates the extent of deformation that occurs when the rubber sealing ring is squeezed.
Selection range
The compression ratio selection range should guarantee that the rubber sealing ring can sustain adequate recovery and provide enough sealing force during compression in real-world applications.
A rubber O-ring that is compressed too quickly risks deforming, aging, or failing before its time. Conversely, a compression rate that is too modest might result in a loose seal that compromises the sealing effect.
Reasonable design and selection are needed for the compression ratio, taking into account the pressure, temperature, medium, and other elements of the real working environment.
Material properties
Consideration must be given to the properties and longevity of the rubber material, since the selection ranges of tension and compression ratio for rubber sealing rings made of various materials may differ.
Working environment
Choose a suitable parameter range after taking into account the unique operating conditions of the rubber sealing ring, including the effects of temperature, pressure, medium, and other elements on its stretch and compression rates.

Sealing effect
Make sure the rubber sealing ring has adequate durability to prolong its service life and can offer a satisfactory sealing effect when in use.
The rubber O-ring's sealing effectiveness and longevity in real-world applications are closely linked to the selection range of its stretch amount and compression ratio. A reasonable selection of the stretch amount and compression ratio range necessitates taking a number of aspects into account, including the sealing effect, working environment, and material qualities. One crucial step in ensuring that the rubber sealing ring can operate successfully in engineering applications is to make sure that it can conform to the shape of the sealing groove and offer stable sealing performance after installation. This may be achieved through appropriate design and selection. In practical applications, the ideal stretch amount and compression ratio range must be chosen in order to guarantee the rubber sealing ring's outstanding sealing performance and dependability. It is also vital to carefully evaluate the unique conditions.
