GYLON EPIX® Gaskets
GYLON EPIX® Gasketing - The Next Generation in PTFE Gaskets
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.
GYLON EPIX® 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.
Designed for increased compressibility, GYLON EPIX® improves performance in misaligned flanges. The consolidation of two thicknesses to one reduces the need to inventory multiple thicknesses. Garlock is dedicated to providing real sealing solutions that meet real world sealing needs. With an improved design, color-coded materials, and single thickness, GYLON EPIX® makes sealing easier.
Severe service PTFE gasketing
Garlock® GYLON® gasketing is a family of severe service PTFE gasketing materials manufactured using a proprietary process that imparts unique physical properties that are not obtainable through conventional manufacturing methods.
The innovative GYLON® manufacturing process reorients the PTFE and fillers in a way that increases the material’s tensile properties and decreases the creep relaxation problems that usually plague PTFE products. In addition, the mixing process creates a homogenous material with consistent, superior physical properties that, unlike inferior skived PTFE sheet gaskets, do not fluctuate from one side of the sheet to another. Plus, our patented thermal bonding process allows us to fabricate gaskets of nearly any size.
Designed for severe chemical service, GYLON® gaskets are color-coded for easy identification and provide superior sealability to reduce process and media loss and fugitive emissions. They also reduce creep and cold flow characteristics.
The Garlock® BLUE-GARD® compressed, non-asbestos (CNA) gasketing line offers a variety of elastomers that provide exceptional sealability and excel in a wide range of services. The unique blend of aramid fibers, fillers and elastomeric binders provides improved torque retention and drastically lowered emissions levels. BLUE-GARD® gasketing offers cost savings by cutting operational costs through reduced waste, maintenance, stocked inventory, fluid loss, and energy consumption.
STRESS SAVER® Gaskets
The Garlock® STRESS SAVER® family of products feature molded, raised ribs that help to create a tighter seal by concentrating the compressive load, ideal for lightweight piping and non-metallic flange applications where low bolt load and chemical resistance are issues. This rib design allows the STRESS SAVER® gaskets to seal where flat rubber and traditional PTFE gaskets will not.
The GYLON® TUFF-RAIL® Family consists of two tank car manway gaskets, GYLON® 3545 & 3504 TUFF-RAIL®. The TUFF-RAIL ® patent pending technology incorporates raised sealing features for a tighter seal in less than ideal bolting conditions, even after multiple cycles. Engineered to a single size, these gaskets fit the most common manways (AAR-1, UTC-1, TRN-1) simplifying gasket selection and inventory requirements. Constructed from our industry proven GYLON® material, TUFF-RAIL ® manway gaskets have been tested for reliability, reusability, and superior performance over other similar PTFE materials.

Aseptic Food Grade
Process and equipment reliability
GYLON BIO-LINE® PTFE material provides exceptional sealing performance for all pharmaceutical and food processing applications and processes. It’s restructured PTFE composition provides safe, durable and consistent sealing performance in a range of challenging environments, including exposure to acids, caustics, sensitive media, low and high temperatures and pressures.
By remaining flexible, tight and flush with the pipe bore, even under high loads, GYLON BIO-LINE® gaskets further eliminate the potential for process material contamination caused by traditional elastomeric seals.

Controlled Swell Sheet Gasketing
The only true “controlled swell sheet” available on the market today.
MULTI-SWELL™ 3760 is the only true “controlled swell sheet” available on the market today. The controlled swell characteristics combined with the higher compressibility allow the 3760 to create an ultra-tight seal in in low load applications, such as gearboxes, compressors, pumps, lightweight lube oil systems flanges, and access covers where traditional cork and vegetable fiber gaskets historically leak.
GRAPH-LOCK® Flexible Graphite Gasketing
GRAPH-LOCK® is composed of pure, exfoliated flake material. It excels in extreme conditions and withstands high temperatures, high pressures, and aggressive chemicals. It also provides excellent resistance and is proven to be fire-safe.
GRAPH-LOCK® gasketing provides a reliable seal as it seals easily under moderate bolt load, offers superior torque retention, retains dimensional stability in high temperatures and seals tightly, even during pressure fluctuations. Flexible graphite is manufactured in such a manner that no organic or inorganic binders and fillers are introduced — the end product is essentially pure graphite with outstanding physical properties. The insertion of wire mesh, stainless steel foil, and tanged metal inserts increase strength and ease of handling.
GRAPH-LOCK® gasketing is available in two grades: industrial grade, which is 98% pure, and nuclear grade, which is 99.5% pure. It is available as standard homogeneous sheet or metal- inserted sheet for applications requiring extra strength.
High Temperature Gaskets
Garlock® 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. New THERMa-PUR® style gaskets provide extreme temp protection using a unique formulation with Garlock’s traditional quality.
Inorganic Fiber Gasketing
Garlock® Inorganic Fiber Gasketing offers excellent thermal stability with minimal weight loss, reduced creep relaxation and improved torque retention. The inorganic fibers have excellent thermal and oxidation resistance, withstanding a continuous operating temperature of up to 550°F (290°C), and maximum spike of 800°F (425°C).
Low cost gaskets that utilize vegetable fiber to seal in low pressure, low temperature applications.
The 2900-series of compressed non-asbestos (CNA) fiber sheet gasket materials provide excellent sealability and improved thermal stability in utility and general service applications. The Garlock® compressed sheet gasketing material primarily contains fibers, rubber and fillers. The aramid fiber options can be combined with a nitrile binder, SBR binder, or Neoprene binder.
