Purchasing Guide

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

  • For procurement requirements that require the use of rubber sealing products, it is recommended to prioritize confirming key technical parameters such as hardness, temperature resistance range, and compression permanent deformation rate of the product to ensure compatibility with the operating conditions of the equipment or pipeline.
  • In different scenarios such as automobile manufacturing, hydraulic systems, or building waterproofing, the material selection of rubber sealing products (such as NBR, EPDM, or fluororubber) needs to be adjusted according to the differences in contact medium and environment.
  • When selecting suppliers, priority should be given to product matching, business qualifications, enterprise activity, industry performance, and enterprises with industry data support or platform statistical information to balance procurement risks and efficiency.
  • In actual procurement, attention should be paid to the cross-sectional shape and dimensional tolerances of rubber sealing products, such as the deviation between the inner diameter and wire diameter of O-rings, which may directly affect the sealing performance and service life.
