Purchasing Guide

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

  • For procurement requirements that require the use of flange gaskets, it is recommended to first verify the pressure rating, material (such as rubber, metal, or graphite), and size specifications to ensure a complete match with the pipeline flange system and avoid sealing failure due to parameter deviations.
  • In chemical or high-temperature pipeline scenarios, flange gaskets with outstanding corrosion resistance and high-temperature resistance, such as polytetrafluoroethylene or wound metal gaskets, should be given priority consideration. Such working conditions require high product stability.
  • When selecting suppliers, reference can be made to standards such as product compatibility, business qualifications, enterprise activity, industry performance, and industry data support. Such suppliers usually provide more stable batch supply capabilities.
  • When purchasing flange gaskets, attention should be paid to the differentiated requirements of gasket structures for different connection forms (such as protruding surfaces and ring connection surfaces). There are significant differences in the application scenarios of flat gaskets and toothed gaskets.
