Purchasing Guide

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

  • For the procurement requirements of rubber seals, it is recommended to prioritize checking key technical parameters such as temperature resistance range and compression permanent deformation rate to ensure compatibility with the equipment operating environment. For example, chemical pipelines need to pay attention to corrosion resistance indicators.
  • When selecting suppliers, reference can be made to product compatibility, business qualifications, enterprise activity, industry performance, and platform statistical information. Such enterprises are usually able to provide stable seals suitable for automotive oil seals or hydraulic systems.
  • The material requirements for rubber seals vary greatly in different scenarios such as food grade production lines or high-pressure valves. EPDM is suitable for outdoor weather resistance, while fluororubber is more suitable for high-temperature oil environments.
  • Long term use of rubber seals in the industrial field requires attention to industry data support from suppliers to avoid the risk of equipment downtime due to batch stability issues.
