Purchasing Guide

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

  • For procurement requirements that require the use of flexible waterproof sleeves, it is recommended to prioritize checking the pipe diameter, pressure rating, and material parameters to ensure compatibility with the pipeline system, especially suitable for damp environments such as building basements or sewage treatment plants.
  • 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 product supply and technical support.
  • In chemical or plumbing engineering, the corrosion resistance and sealing performance of flexible waterproof sleeves are key indicators. When purchasing, the corresponding rubber ring material and flange type should be selected according to the characteristics of the medium.
  • Different installation scenarios have differentiated requirements for the length and expansion of the casing, such as reserving sufficient displacement space when connecting through walls and pipelines to avoid leakage risks caused by thermal expansion and contraction.
