About Our Locking Window Gaskets

One-piece locking window gaskets are specialized seals designed to secure and protect stationary windows in various applications, such as vehicles, boats, and industrial equipment. These gaskets combine the sealing and locking functions into a single, integrated piece, ensuring a tight and secure fit around the window frame.

Window Gasket Seal Solutions

Made from durable, flexible EPDM rubber, they provide excellent resistance to:

  • Weather
  • UV rays
  • Temperature fluctuations

The locking mechanism simplifies installation and enhances the seal's effectiveness, preventing water, air, and debris from penetrating the window edges. Overall, one-piece locking window gaskets offer a reliable, long-lasting solution for maintaining window integrity and performance.

Rubber Window Gasket Applications

Rubber window gaskets have a variety of applications, providing essential sealing and protection for numerous settings. In the automotive and heavy machinery industries, they are used to secure and seal stationary windows, preventing water and air leaks while reducing noise. 

In marine environments, these gaskets protect stationary boat windows and hatches from harsh weather conditions and seawater intrusion. 

Industrial machinery and semi-trucks also benefit from rubber window gaskets, which ensure that control panel window and passenger door viewing windows remain tightly sealed against dust and contaminants.
