During the selection and use of silicone hoses, you may encounter some common issues. Below are some common problems and their solutions:

7 Common Silicone Hose Problems

1. Yellowing or Discoloration of Silicone Hoses

Issue: Silicone hoses may turn yellow or discolor due to the following reasons:

  • Prolonged exposure to sunlight
  • Pigmented substances transported inside
  • Aging of silicone hoses
  • Avoid exposing silicone hoses to sunlight as much as possible
  • Choose transport materials that are free from pigments
  • Regularly replace silicone hoses

2. Bubbling on the Inner or Outer Walls of Silicone Hoses

Issue: Bubbling on the inner or outer walls of silicone hoses may be caused by:

  • Improper raw material proportions during production
  • Immature production processes
  • Inappropriate usage environment of silicone hoses
  • Purchase silicone hoses produced by reputable manufacturers
  • Strictly follow the instructions for using silicone hoses
  • Avoid exposing silicone hoses to high temperatures, pressures, chemicals, etc.

3. Breakage of Silicone Hoses

Issue: Silicone hoses may break due to:

  • External mechanical forces
  • Aging of silicone hoses
  • Improper installation of silicone hoses
  • Handle silicone hoses with care to avoid excessive pulling or squeezing
  • Regularly inspect silicone hoses and promptly replace aged hoses
  • Follow the installation instructions strictly

4. Insufficient Heat Resistance

Issue: In high-temperature environments, silicone hoses may soften, deform, or age, affecting their lifespan and performance.

  • Ensure the selection of silicone materials with sufficiently high heat resistance, meeting the project’s maximum operating temperature requirements. Consider using high-temperature resistant silicone hoses, which typically withstand temperatures up to 250°C or higher.

5. Chemical Compatibility Issues

Issue: Certain chemicals may react incompatibly with silicone hose materials, causing hose material expansion, deformation, or corrosion.

  • When selecting silicone hoses, understand the chemical nature of the handled liquids or gases, and choose silicone materials with good chemical stability. If in doubt, consider chemical compatibility testing or consult silicone hose suppliers.

6. Size and Connection Issues

Issue: Hose sizes may not match existing equipment or pipeline systems, or connectors may not meet installation requirements, resulting in leaks or instability.

  • When selecting silicone hoses, accurately measure pipeline and fitting dimensions, and choose hoses that meet specifications. Ensure hose connectors are compatible with existing equipment and pipeline systems, using correct installation methods and sealing measures to ensure safe and reliable connections.

7. Aging and Damage of Silicone Hoses

Issue: Long-term use or improper maintenance may cause silicone hose surface aging, cracking, or abrasion, affecting its performance and lifespan.

  • Regularly inspect and maintain silicone hoses, promptly replacing aged or damaged hoses, and avoiding scratches from hard or sharp objects on hose surfaces. Clean the interior of hoses as needed to prevent dirt and deposits, maintaining fluid transfer efficiency.
