Lip Seals 101: Common Questions About Lip Seals From Curious Consumers

Seals, gaskets, and filters are all common small parts of industrial pieces of machinery and equipment, but these are also some of the most commonly misunderstood components, especially lip seals. Lip seals are rubberized seals that are specifically designed to fit over a usually rounded lip of an opening of a piece of machinery. The seal's purpose can be to provide a tight closure or to retain moisture so a unit doesn't leak. Here is a look at some of the most common questions about lip seals

What are the best features to look for in quality lip seals?

There are many different lip seals on the market, so finding the best can seem to be somewhat of a challenge. However, there are specific attributes to look for in lip seals that will tell you they are quality made. A few examples include:

  • the lip seal is advertised as quality tested
  • the lip seal is heat resistant to a high-degree temperature
  • the lip seal has a product warranty from the manufacturer

Are a lip seal and a radial shift seal the same thing?

Essentially yes. Lip seals and radial shaft seals are the same thing and are often used as interchangeable terms, although this is not technically correct.  Because radial shafts utilize a lip seal most commonly, the lip seal often gets called a radial shaft seal, even the lip seal can be used for a variety of other applications. A few examples of other applications for lip seals include for hydraulic pumps, power steering pumps, valve stems, and even axle connections. 

What are some signs that a lip seal has gone bad?

The signs that should tell you if a lip seal has gone bad can depend on what application the seal is being used in. However, there are some general signs that a seal should be replaced as soon as possible. For example, if the seal is cracked, has notches taken out, or appears to be rigid instead of flexible, it is a sign that the seal is old and should be replaced because it will not effectively seal off the closing or coupling. In some cases, a lip seal can also become warped if it has been exposed to extremely hot temperatures. This is hard to see with a naked eye while the seal is still in place, but will usually leave you with leaking fluids or an improper closure.
