KB25

KB25 profile is a heavy-duty spring energised seal commonly used in heavy industry such as steel plants as a good replacement for rubber fabric seals that fail due to compatibility issues. The seal requires a 2-piece housing for installation purposes and correct function.

The helical spring energiser within the seal provides the initial pre-load for static sealing while the system pressure enhances the sealing function by further energising the sealing lips. The seal is used in areas where high temperatures can be seen and/or where a seal is required that has broad fluid / media compatibility.

The seal has a useful operating speed and can be manufactured from non-abrasive PTFE materials to protect hardware components from wear and abrasion.
