Purchasing Guide

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

  • For procurement requirements that require the use of sealing accessories, it is recommended to prioritize checking key technical parameters such as pressure resistance level and temperature adaptability range to ensure compatibility with pipeline systems or equipment operating conditions. For example, the chemical industry needs to pay attention to corrosion resistance performance.
  • 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 solutions.
  • Sealing accessories used in high temperature and high pressure scenarios require special attention to material creep resistance and sealing surface accuracy, while the food and pharmaceutical industry needs to consider material selection that meets hygiene standards.
  • Different application scenarios such as hydraulic systems and vacuum equipment have significant differences in the requirements for the elastic modulus and wear coefficient of sealing components. When purchasing, suppliers can be requested to provide targeted test reports as a reference.
