Impervapac® gasket material from Auburn offers a superior alternative to rubber gaskets and cork-rubber gaskets in low flange pressure applications and low internal pressure applications. A unique fiber composition with high rubber content makes Impervapac® an ideal choice for sealing gases and fluids, while permitting reduced thickness for additional economy. Impervapac® is pliable, flexible, bendable, and easy to die cut into specific gasket shapes. Some of its typical usages involve die cut gaskets for water pumps, marine equipment, automobile engines, aftermarket gaskets, gasoline engines, oil seals, dust seals, and basic shim/spacer applications.

Standard Products

N-8051 is a light-duty material intended for use with die cut gasket that involve low internal pressure and reduced flange pressure up to 13.8 Mpa (2000 psi). It has a nitrile binder for resistance to oil and is intended for applications with short duration maximum temperatures up to 180°C (350°F).

Adhesive Backings

Auburn is capable of taking any Impervapac® material and applying adhesive to one or both of its surfaces. Auburn adhesives are available for both raw materials and finished die cut gaskets including die cut shims, washers, spacers, gaskets and seals. Auburn works with dozens of popular adhesives including:

 The use of adhesives has many distinct advantages that include eliminating the messy job of cementing during assembly operations, assuring a uniform amount of adhesive per part, and reducing labor time in assembly operations.

Material Availability

Impervapac® is available in many standard thicknesses - .010”, .015”, .031”, .047”, 062” and master rolls that are 40” wide. These products can be further supplied in a variety of forms that include continuous length rolls, sheets, precision strips, slit-to-width rolls and custom die cut gaskets.

Manufacturing Capabilities

Auburn’s specialty is fabrication of precision die cut gaskets with tight tolerances and clean cut edges for any production quantity from a single piece up to millions. All die cut gaskets are cleaned, inspected and neatly packaged prior to shipment.


For a simple part such as a plain die cut washer, a disc, a rectangular pad or a uniform-width strip, a house-tool is very often available at no additional cost. For a more complex part that requires a tool, a steel rule die is built. A steel rule die’s cost is usually quite minimal ($95.00-$125.00 range) and its production time is ordinarily only 1 or 2 days, at which time a first article sample is sent to the customer for a final approval.
