The main qualities we keep readily available are:
Garlock
In 1994, Garlock introduced GYLON® Style 3545 for low bolt load applications. It was designed specifically to seal pitted, warped or wavy flanges. Featuring soft, compressible outer layers and a rigid PTFE inner core, Style 3545 is ideal in situations where a rigid gasket is required, such as hard-to-reach piping systems, valves and flanges. The layers of rigid PTFE and microcellular PTFE are sandwiched together using the proprietary GYLON® thermal bonding process, rather than adhesives, for longer gasket life. Style 3545 is so innovative, it received the 1995 Vaaler award from Chemical Processing magazine.
The Garlock family of GYLON® products has evolved over the years with a focus on quality to meet and exceed customer expectations. The use of Employee Involvement, Statistical Process Control, Vendor Assurance Programs, and a continuous improvement philosophy continues to guarantee end users the highest quality products available. Testing is performed regularly on all styles and thicknesses to ensure the consistency of Garlock quality in GYLON® sheets. Quality American-made products, 47 years of experience, on-time delivery and value-added service programs, all are reasons why the GYLON® family of products has become such a major sealing component in industry today.
Gylon 3545: highly compressible microcellular PTFE with a rigid PTFE core for improved handling. The GYLON® 3545 designed to compress and conform to irregular or damaged surfaces, making it suitable for flanges that generate lower compressive stresses, such and glass-lined flanges and equipment. Suitable for strong caustics, strong acids, hydrocarbons, chlorine, cryogenics and glass-lined equipment. Conforms to FDA regulations.

Gylon EPIX 3501-E: EPIX technology will provide superior functional performance by combining the traditional attributes of GYLON® with an innovative surface design. It offers a broader range of applications than traditional PTFE gaskets that are used in worn and pitted flanges. In addition, GYLON EPIX® delivers the tight sealing and load retention properties of 1/16” (1.6mm) and the conformability of 1/8” (3.2mm). The hexagonal profile provides improved compressibility and recovery. The profiled surface reduces the contact area during initial compression to concentrate the compressive force of the flange for improved sealability.
- One thickness does the job of two
- Seal performance and load retention equal of 1/16” (1.6mm)
- Compressibility and forgiveness/conformability of 1/8” (3.2mm)
- Patented hex profile creates superb sealing and ability to conform to imperfect flange surfaces
- Same material as traditional GYLON®
Gylon 3510: high performance, barium sulfate filled PTFE gasket material. GYLON® 3510 PTFE gasket is designed for use in strong caustics and toxic chemicals, such as chlorine, ammonia, and phosgene, where initiating and maintaining an extremely tight seal is critical. In addition, the GYLON® 3510 provides exceptional performance in monomer services. Suitable for strong caustics, moderate acids, chlorine, gases, water, steam, hydrocarbons, and cryogenics. Conforms to FDA regulations. Style available for oxygen service as well.

Flexitallic
Sigma® 500: High chemical resistance, biaxially orientated PTFE containing hollow glass microspheres. Offers enhanced compressibility for low bolt loads and improved flexibility over conventional calendered and graphite sheets. It is capable of creating a seal across a wide range of gasket stress. This makes the product suitable not just for use in standard metallic flanged connections and also in load compromised bolted connections; such as those applications involving glass lined, plastic and thin or distorted metal flanges. Sigma® 500 material is inherently clean, making it suitable for use in industries where product contamination may be of concern such as food, beverage and pharmaceuticals. Suitable for sealing most chemicals across the whole pH range (0-14) with the exception of molten alkali metals, fluorine gas, hydrogen fluoride or materials which may generate these. Available for Oxygen service.
