The Benefits of Custom Seals

Custom Seals – The ultimate guide & CNC Machining

When choosing the correct sealing solution for the application/industry, custom seals offer a range of fantastic benefits. Whilst standard seals serve a purpose for common applications, custom seals should be considered when precision, reliability, longevity and optimal performance in challenging environments are crucial to their operations and overall success.

If you are unsure which option would be best for your application, here are 5 reasons choosing custom seals may be the better alternative:

Perfect Fit & Enhanced Performance

  • Standard seals may not fit complex or unusual dimensions. Custom seals are designed precisely for the specific equipment, ensuring a perfect seal and preventing leaks and contamination.
  • Custom seals can be engineered with specific profiles, shapes and tolerances to minimise friction.

Superior Durability & Longevity

  • Material selection with standard seals may be quite limited. Custom seals allow for the use of specialised materials.
  • When a seal is specifically designed for its operating conditions and made from the optimal material, it experiences less wear and tear, leading to a longer service life.

Reduced Maintenance & Operational Costs

  • Whilst the initial investment may be higher, the enhanced durability and tailored performance mean fewer replacements and less-frequent maintenance.
  • Custom seals minimises the risk of leaks, contamination and equipment failure – reducing the likelihood of safety hazards and costly repairs

Challenging Conditions

  • Extreme temperatures, high pressures, harsh environments (exposure to UV, water, oil or aggressive chemicals) often require custom material to maintain elasticity, prevent extrusion and minimise friction and wear.

Regulation and Compliance Requirements

  • Certain industries e.g. Aerospace, Food & Beverage and Pharmaceuticals have strict regulations and standards that need to be met. Custom seals can be manufactured to adhere to these certifications.
