Prepare before inflating	1.Conduct a comprehensive inspection of the appearance of the sealing ring to ensure there are no defects such as damage,cracking,air leakage,scratches,etc.If any problems are found,the product must not beused. embedded in the sealing groove without any distortion,compression, offset,or folding,and is perfectly and smoothly in contact with the sealing surface. 4.Equip with a dedicated adapter for inflation and pressure testing equipment.Preferably choose a device with an accurate pressure gauge. The pressure gauge accuracy must not be lower than 0.O1 MPa.Avoid sudden pressure increases or decreases.	If the installation is not properly done,the interface is clogged,or the equipment does not meet the standards, the inflation operation must not be initiated.

Do not continue to increase pressure. Important Notes 3. Regular inspections are required for long-term use. Replace the seal ringin time if it becomes aged or loses elasticity. 4.Do not scratch the surface of the sealing ring with sharp objects to avoid causing air leakage points. 5.When the temperature is less than OC or more than 6oC,reduce the usage pressure.	Inappropriate operation may lead to the failure of the seal and damage to the product.

THEMAIN CLASSIFICATION OF CROSS-SECTIONS

It has a large expansion stroke and good sealing performance,makingit suitable for application scenarios that require a large expansion volume and sealing performance

This product is a modified version of the common concave type,suitable for situations with an extremely high expansion ratio.It is ideal for applications with large sealing gaps.Due to its tendency towards a high ejectionratio,its pressure resistanceisslightly inferior and it is not suitable for high-pressure sealing conditions.

The third category

This type of product is mainlyused for radial expansion sealingand canbe used asafixture. When expanding,the contact surface is wide and the sealing effect is good. It has excellent pressure resistance performance when the sealing gap is small and is widelyused in various sealing situations.

he fourth category/////// □口

The shape is regular,the expansion force is uniform, and the expansion distance is small.It can withstand high pressure,hasa good sealing effect,is durable and easyto replace.Itis suitable for occasions where the expansion requirement is not high but the sealing strength requirement is high, such as steam sealing,etc.

The fifth category

This type of product is quite similar to the fourth category.By optimizing the design of the sealing surface,the sealing performance of the sealing ring against particles,dust and solutions has been enhanced. It is often used for sealing in pharmaceutical and papermaking equipment. This type of product has good pressure resistance and durability.

The sixth category

宝 Z m

It has a base,which is convenient for fixation, not easy to shift or fall off,and has good stability. It has a relatively large expansion capacity and is suitable for sealing conditions where a large expansion volume is required.
