GASKETS & GASKET MATERIALS

Gasket Materials

GREEN GENERAL PURPOSE GASKET SHEET
Excellent gasket material with good chemical and petroleum resistance. Excellent sealability in oil, gasoline, mild chemical, water, and other fluid applications. See our commercial flange gasket chart for information on standard gasket sizes.

COMPRESSED GASKET SHEET with NITRILE BINDER
A premium sheet constructed from aramid fibers and a Nitrile binder. This material serves in water, aliphatic hydrocarbons, oil, and gasoline applications Provides excellent sealability and drastically lowered emission levels.

COMPRESSED GASKET SHEET with SBR BINDER
Constructed from aramid fibers and an SBR binder this material serves in water, inert gases, and saturated steam applications (saturated steam under 150psi). Provides excellent sealability and drastically lowered emission levels.

COMPRESSED GASKET SHEET with NEOPRENE BINDER
Constructed from aramid fibers and a neoprene binder this sheet serves in water, refrigerant, oil, fuel, and saturated steam applications (saturated steam under 150psi). Provides excellent sealability and drastically lowered emission levels.

COMPRESSED GASKET SHEET with EPDM BINDER
Constructed from aramid fibers and an EPDM binder this material serves in water, inert gases, and saturated steam applications (saturated steam under 150psi). Provides excellent sealability and drastically lowered emission levels.

INORGANIC FIBER GASKET SHEET
Constructed with inorganic fibers with a nitrile binder. Reduced creep relaxation and improved torque retention provide optimal sealing. Most inorganic fiber gasket sheets are ABS Fire Safe Type approved.

OIL PAPER / VEGETABLE FIBER
Premium grade vegetable fiber sheet packing, efficiently saturated with a glue-glycerin impregnant rendered insoluble by means of a tanning agent to create a strong, flexible, all-proof packing.

HIGH-TEMPERATURE COMPRESSED SHEET
These high-temperature gasket materials excel in the harshest conditions- intense heat, high pressure, saturated steam and hot oils. The complex engineering process involves laboratory tests for fire safety. They maintain effective seal during pressure and temperature fluctuations. Superior torque retention lowers leakage rates and reduces maintenance time.

GRAPHITE GASKET MATERIALS
Graphite Gasket Products are flat gasketing materials composed of pure, exfoliated flake material. These materials excel in extreme conditions, withstand high temperatures, high pressures, and aggressive chemicals, and are proven fire-safe. Graphite 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 graphite with outstanding physical properties. The insertion of wire mesh, stainless steel foil, and tanged metal inserts increase strength and ease of handling.

PTFE GASKET PRODUCTS
PTFE Gasket Products are flat PTFE gasketing materials. These high-performance PTFE materials are manufactured using a process that imparts unique physical properties, which are not obtainable through conventional manufacturing methods.

Gasket Products

PTFE JOINT SEALANT
PTFE joint sealant, specially processed, 100% pure PTFE on a roll, provides soft, highly compressible gasketing for longer life and trouble-free sealing. Its form-in-place versatility also cuts maintenance and storage costs. The high compressibility of this product enables it to effectively fill flange imperfections for a tight, leak-free seal. Under pressure, it provides a very wide, thin ribbon-like joint sealant. Unlike conventional PTFE which is prone to cold flow, TJS has good creep resistance and bolt torque retention properties. PTFE joint sealant does not support bacterial growth or cause product contamination and is FDA compliant. It has virtually no shelf-life concerns since PTFE is unaffected by normal environmental conditions.

SPIRAL WOUND GASKETS
Metal gasket made spiral winding metal material and adding a sealing filler. Available with inner or outer rings or both.

FLANGE GASKETS
Gasket cut from various materials to seal standard ANSI flanges and other common flange dimensions.

SPIRAL WOUND MANWAY & HANDHOLE GASKETS
Gaskets for boiler handhole, tubecap and manhole covers incorporating the unique Flexitallic Spiral Wound profile and specially manufactured with graphite filler, are ideal for corrosive, high pressure or temperature duties. Flexitallic’s anticipation of developments in modern steam generating and engineering equipment and ability to design to specific requirements are the guarantee of the perfect seal at minimum maintenance cost with consistently high standards of performance.

SELF-LOCATOR GASKETS
The SELF LOCATOR gaskets are a complete stainless steel containment of a sealing element offering a true compression seal. The patented design gives you long term reliability without flange welding and eliminates misalignment on installation. Due to its universal sizing, one gasket fits all flange pressure classes, eliminating the chance of incorrect gasket selection. The most important feature of the gasket is the high unit load generated by the narrow sealing area provides a considerably higher flange clamping pressure and a better seal at a lower clamping force. The standard gasket material is 316 SS, with two (2) tracks of Flexible Graphite sealing elements. Specialty gasket material and/or sealing elements are available as options.

TOPOG-E® GASKETS
The steam boiler market makes extreme demands on gaskets; Topog-E® molded rubber gaskets are specifically formulated to meet and exceed these demands and deliver industry standard performance.
