All Seals can supply gaskets in a variety of materials to cover all your sealing needs. With either small sample runs and high production usage, we have you covered.

Gaskets are an integral component of any device which requires the confinement of a gas or liquid. They compensate for the unconformity of mating surfaces. These surface irregularities may be minute or large depending on the purpose of the device but in all cases, the gasket is required to compensate for the difference while limiting the flow of fluid in either direction. Gaskets differ from seals in that gaskets are normally cut from sheets or rolls while seals are formed individually in their own configuration. A flat cut gasket is derived from material of specific thickness and to a configuration that is designed for a specific application.

If the gasket material is in sheet or roll form, a gasket fabricator can convert it into parts. However, the material characteristics will determine the personality of the end product. Gasket materials that are hard and thin can be convertd to tighter dimensional tolerances than gasket materials that are soft and thick. Accordingly, 90 durometer rubber 1/32 inch thick can be cut to more precise requirements than 30 durometer rubber 1/8 inch thick. Some gasket fabricators specialize in certain types of material. One fabricator may have unique capabilities in the processing of sponge rubber products where another fabricator may have acquired equipment more suitable for elastomeric rubber. Another specialization is the ability to process sheets rather than roll goods. One fabricator may be heavily invested in platen presses while another may specialize in slitters and punch presses with continuous feed and takeoff.
