We recently updated our Gasketing webpages to provide our customers with much more robust product information, to help you along your journey of finding the right gasket for your application. Visit our Non-Asbestos, Metal, Elastomeric, or ePTFE Gasket Tape pages to learn more.
When you’re specifying a gasket for even the simplest application, it is important that the gasket supplier know all the operating parameters.
There are five major pieces of information needed to select the appropriate gasket, known by the acronym S.T.A.M.P.:
While gaskets are most often used in standard ANSI flange connections, non-standard flanges can also be found throughout a plant. In dealing with non-standard flanges, it is VERY important to obtain as much detail as possible about the contact dimensions (the portion of the gasket actually being compressed) and the fasteners or bolts being used (size, grade, quantity). This information is used to calculate the contact area and available assembly stress – a key factor in the selection process, as an improperly loaded gasket could result in premature equipment failure.

Garlock has expanded their Ultra Low Emissions family of products to include a spiral wound gasket. The FLEXSEAL® ULE is designed for use where leakage control is critical and the aggressive application requires a spiral wound design. It’s manufactured using high performance graphite, and offers maximum protection against oxidation. The standard design includes an inner ring and outer ring, as well as preformed metal wire to enhance compressibility and sealability. The FLEXSEAL® ULE spiral wound is another product born from Garlock’s customer driven innovation.

GYLON EPIX™ is a newly developed family of PTFE gaskets. It is manufactured using a patented, profiled surface based on our proven Fawn, Off-White, and Blue GYLON® to create highly conformable materials for optimum sealing performance.
THE EPIX™ DIFFERENCE
GYLON EPIX™ and a traditional full face gasket were installed in a 3”-150# flat face flange at 120 ft.lbs. with pressure sensitive film. The film revealed that the traditional material saw heavier loading-near and around the bolts, and lighter loading at the points furthest from the bolts. The GYLON EPIX™ was able to distribute the load more evenly and prevent the low loading phenomenon.
The pressure sensitive film was then analyzed with special software that translate the various shades of red into a full color spectrum that provides a better visualization of the stresses that were developed on each of the gaskets. Again, while the traditional gasket saw areas of lower stress (green and blue areas), the hexagonal pattern in the GYLON EPIX™ concentrated and distributed the stress more evenly across the entire gasket.

GYLON EPIX™ is a family of gaskets that effectively seals a broader range of applications and is more forgiving during the installation process. It allows the end user to save valuable turn-around time, reduce re-work, and lower costs, helping them to finish ahead of schedule and under budget.
GYLON EPIX™ features a hexagonal surface profile that provides the torque retention and blowout resistance of a thin gasket and the conformability of a thicker gasket. GYLON EPIX™ Style 3504 EPX is a high performance, aluminosilicate microsphere filled PTFE sheet material designed for use in moderate concentrations of acids, and caustics, as well as hydrocarbons, refrigerants, and more.
Customer reported problems with continuous leaks that required ongoing maintenance and attention taking manpower and resources away from other critical operations for the plant.
