CHALLENGES FACED BY CUSTOMER
The customer’s chemical treatment vessel has nonstandard rectangular flanges with a limited number of bolts. The limited bolting resulted in inadequate compression to seal the gasket and the non-standard shape made the use of a molded engineered gasket unfeasible. When tested, expanded PTFE leaked. There was no alternative known at that time so the mess of crystalized leaking media was accepted as normal.
OPERATING CONDITIONS AT CUSTOMER FACILITY
- Temperature – 86°F (30°C) - 104°F (40°C)
- Application – Custom rectangular flange
- Media – Dilute Caustic Soda
- Pressure – 50 psig (3.5 bar-g)

The GYLON® Style 3522 material is made of 100% pure PTFE with no fillers or additives, making the material ideal for the most demanding, high purity requirements. Industries such as food, pharmaceutical, semi-conductor, recognize the uniformity of GYLON® 3522 that makes it an ideal gasket choice for those critical applications that cannot risk process contamination or premature failure.

High temperature gasketing excels in the harshest conditions—intense heat and high pressure. These high performance gasket materials have been laboratory tested for fire safety. They maintain an effective seal during pressure and temperature fluctuations, and their excellent torque retention lowers leakage rates and reduces maintenance time.
This blog post will examine the five types of high temp gasket material that GFS carries from Garlock and Thermoseal Klinger.
- Garlock Style 9800
- Garlock Style 9850
- Garlock Style 9900
- Garlock Therma-Pur 4122-FC Ring Gasket
- Klinger PSS High Temp

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.

This blog will discuss the differences between ASME flanges and AWWA flanges and the gaskets associated with each.
ASME flanges are the most widely used and specified flanges throughout industry in North America. Flange sizes ½” through 24” fall under ASME B16.5 and flange sizes 26” through 60” fall under ASME B16.47. Within ASME B16.47 there are series A and series B flanges, with the noticeable differences in most cases being the bolt size and/or bolt quantity.
