The Ultimate Engineers Checklist For New Application & Replacing Seals

The 30th October marks National Checklist Day, an opportunity to appreciate the value of checklists, and how they can maximise productivity and opportunities. To celebrate we have put together the ultimate list for selecting a new seal, whether that be for a new application or replacing an old seal.

Size, temperature, application, media, pressure and speed (STAMPS) are methods implemented throughout engineering circles, previously used this approach in a previous blog around eliminating contamination in dairy.  

We implement the STAMPS methodology throughout this blog to ensure we cover every step an engineer should take before getting in touch to fulfil their application needs.

Description of your requirement

It is important to start off by providing a general description of your requirement and specifically what the application of the seal is. Whether it be food & pharmaceutical or oil & gas,  it is important you select the correct seal due to the potential of contaminating the environment they operate in.

It’s important to specify whether the seal is needed for a new application or to replace an existing one so that a member of our expert team can advise you accordingly.  


When searching for your solution, go down the following checklist to provide the required details for the right specification:

  • Diameter (including tolerances)
  • Surface finish
  • Surface hardness
  • Chamfer detail (to allow fitting of the seal)
  • Does the application use a shaft sleeve?

This part of the list specifically correlates to running surfaces. However, if the application is for housing, the diameter, housing width, surface finish and installation chamfer should be noted.

Operating conditions

The operating conditions for seals can be tough and selecting the right product for a specific application is crucial to the quality and reliability to the seal’s performance.

It is important to outline the exact conditions the seal will be operating in and here is a checklist to make sure you’re receiving the correct advice and seal for your application:

  • Pressure - consider both airside and non-airside. Is the seal continuously pressed?
  • Temperature - consider operational, design and testing.
  • Lubrication - are you working with oil or grease? Is the oil level on the centre line, below or above?
  • Speed - consider the maximum operating speed (rpm), maximum design speed (rpm), end float (mm) and runout (mm)

Now that you have created your list and checked it twice, you’re ready to get in touch with our expert team. Contact us now to discuss your sealing requirements or alternatively, check out this guide on applying STAMP in dairy process lines.
