THE USE OF O-RING
Yong Leng Tdg Co offers wide range of O-Ring in different sizes and application purposes. These O-Rings are typically manufactured from elastomeric material and are cut in torus or donut shape. These effectively form a static or dynamic seal to applications in need of secured and tight enclosure against any loss of pressure or leak on materials being contained.

Static seal is achieved using specific o-ring that holds a pressure or maintains pre-set range of vacuum while Dynamic seal is necessary when there are motions happening in between surface that can either be reciprocating or rotating. When installed, these o-rings compresses and deforms slightly into the free space within the groove thus, forming stable sealing feature. There are special o-rings available that are capable of handling or sealing thousands of PSI pressure. Being one of the most common seals used in the design of machines, o-rings are manufactured with lesser expensive materials and easy procedures, making the seal affordable to every industry. With its reliable and simple mounting requirements, the o-rings are typically described by material com,position and hardness. These are made available with variant sizes as per specific industry standards and are being measured through its inner and outer diameters.

Select from our wide selection of o-rings according to metric or inch sizes, chemical compatibility, quality, quantity, cost, application temperature, lubrication requirements and sealing pressure.
