Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement requirements that require the use of sealing rings, it is recommended to prioritize checking key technical parameters such as inner diameter, outer diameter, and material hardness to ensure compatibility with equipment interfaces, such as the significant differences in specifications between hydraulic systems and chemical pipelines.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support. Such suppliers can usually provide more stable sealing ring supply and working condition adaptation solutions.
  • Sealing rings used in high temperature or corrosive environments should pay attention to their temperature resistance range and chemical corrosion resistance, for example, the selection criteria for food processing equipment and petroleum pipelines are completely different.
  • In different application scenarios such as automotive engine or water pump assembly, there are differences in the compression ratio and wear resistance requirements of sealing rings. Before procurement, it is necessary to clarify the actual operating parameters to avoid the risk of failure.

Knowledge Base

Q

The material of the O-ring seal is hydrogenated nitrile rubber and EPDM rubber, which have strong performance advantages such as sealing, shock absorption, aging resistance, weather resistance, and high pressure resistance. Filling the O-shaped rubber sealing ring at the connection of the pipeline joint can block the medium from passing through the leakage channel, and play a role in water tightness and air tightness. The quality of the O-ring rubber seals used in our company's pipeline system has been approved by the national industry
