Tru-Form Manufacturing entered the Gaskets and Seals business through our acquisition of Advantage Seals and Gaskets allowing us to expand our customer reach with additional capabilities. Gaskets are compressible rings or sheets that are designed to form an airtight seal or barrier between two metal surfaces. They are generally used to avoid any seepages and leaks from liquid and gas. Gaskets are built to operate under extreme temperature and pressure fluctuations. As such, gaskets are available in a wide range of metallic and non-metallic materials such as steel, paper, fiberglass, beryllium copper, neoprene, Teflon, rubber, silicone, cork, felt, plastics, polyurethane, corrugated and serrated metal and several others. Gaskets are also available in various shapes and sizes.

​

When gaskets are compressed between two objects they fill in the microscopic spaces between them. This process then forms a seal that is designed to help keep liquids, gases and dirt from entering the components. If a gasket can keep the objects free of contamination then the machinery will last longer and work more efficiently and consistently.

​

It is generally thought that the stronger the compression is, the better the gasket will work and the longer it will last. If there isn’t much pressure placed on the gasket it could move around or open up and allow substances to get through it through. Hot compression tests are performed on gaskets to make sure that they can stand up to the pressure. These tests place both constant pressure and temperature on the gaskets to measure the effectiveness of the seal. Gaskets are often used in situations where the compression pressures can reach up to 2000 pounds per square inch (PSI) or higher. It is important that the proper gaskets are used that are designed to handle the pressure of the job. Gaskets are used in a variety of applications such as plumbing, automotive, high temperature, valve cover, header and industrial. Common gasket design configurations include: pre-cut compression, sheet and die-cut, strip, ring, spiral, flange, tape, sanitary, window and custom-made gaskets. Sheet and die-cut gaskets are flat sheets that are either pre-cut from a die or cut prior to assembly. While spring finger gaskets are available in strips, tape gaskets are flat. Sanitary gaskets find usage in the pipelines for processing of the food and pharmaceutical industry. Some types of gaskets are also designed to shield against electromagnetic and RFI disturbance.

Tru-Form uses over 20 machines including clicker, travel head, and others as well as a wide variety of material in the production of gaskets. Slitting is completed in house.
