GORE® Gasket Tape Series 500

Saves You Time, Money and Trouble

GORE® Series 500 Gasket Tape

GORE® Series 500 Gasket Tape represents the latest advancement in worry-free sealing performance and efficiencies for steel piping and equipment. This cutting-edge product delivers dramatically improved creep resistance to maximize the operational reliability of large steel flanged applications.

GORE® Series 500 Gasket Tape fits any shape instantly. The highly compressible tape forms a very tight seal that is long-lasting while also handling the rigors of virtually any chemical process.

Unlike traditional large gaskets, GORE® Series 500 Gasket Tape is formed in place quickly and easily. Customization at the time of installation eliminates the long lead times for ordering pre-cut gaskets and minimizes the need for extensive gasket inventories.

GORE® Series 500 Gasket Tape is brought to you by the leader in ePTFE technology, delivering knowledge, integrity and proven results - along with decades of experience working with processing plants throughout the world.

Technical Data

100% expanded PTFE (ePTFE), with multi-directional strength

Temperature Range of the Material
-269ºC to 315ºC (-452ºF to 600ºF)

Chemical Resistance
Chemical resistance to all media pH 0–14, except molten alkali metals and elemental fluorine.

Operating Pressure
The specific application governs the operating range of the installed gasket due to the strong influence of many factors, such as operating temperature, flange size, gasket stress, and installation practices. Please consult Gore for application engineering support when operating pressures exceed 40 bar (580psi).

Shelf Life
The ePTFE gasket is not subject to aging and can be stored indefinitely. To minimize adhesive degradation store the product in ambient conditions.

* Recognizing the absence of standard tests for form-in-place gaskets, Gore has leveraged the latest industry test methods to characterize the perfor- mance of GORE® Series 500 Gasket Tape. Creep relaxation, sealability, and crush data is based on EN13555, a European test standard for ring gaskets that defines parameters for flange design. These tests were conducted with a fixture stiffness of 500 kN/mm. Creep relaxation was measured at the corresponding minimum stress to seal using 30mm wide strips.

Graph of Creep Resistance

Creep resistance data based on EN13555 using 15mm x 3mm tape formed into a 150mm skived ring. PQR values were obtained at 30 MPa initial gasket stress at 150ºC.
