Greene, Tweed's unsurpassed expertise in elastomeric and thermoplastic compounding has resulted in the design of this exceptionally long-life, low-friction seal. The Bandseal (GTB) is a self-actuating extrusion resistant seal combining low breakout and running friction with minimal leakage over extended service life. The seal is constructed of premium grade PTFE sealing caps and elastomer energizers. Greene, Tweed's GTB Bandseal is a compact single-acting seal for sealing reciprocating rods but is also available as a single-acting cylinder bore seal. The Bandseal has no stickslip effect. Its fluid feedback capability means the Bandseal cannot cause a pressure trap when assembled in tandem arrangements. The GTS Bandseal operates in temperatures ranging from -85°F (-65°C) to 500°F (260°C) with pressure up to 200 bar standard (higher pressures are possible).

This silicone-based liquid gasket fills gaps on a flange surface and thus completely prevent leaks. When cured, it forms an excellent rubber-like elastic body offering excellent resistance to vibration and shock. Also it has an excellent resistance to heat, and effectively seals joints that are subjected to high temperature. Select the product that best meets the needs for a particular location or set of working conditions.

Essential part of which depends the perfect running and security of entire plants, the sealing device must be definited since the products studying process, and taking into account all conditions of use ; but nevertheless, some sealing problems can arise in duty. That is the reason why Jicey conceives, designs and makes at your demands the flat stactic sealing devices that you need, around its basic technologies: industrial lamination and the carving of thin and ultrathin materials, but also in all materials and all shapes according to your plans.

Metal bead gaskets become more and more important as secondary gaskets in engine construction and for compressors.
Frenzelit is specialised in the manufacturing of "tailor-made" gaskets. With state-or-art technical systems at hand, e.g. various CAD systems, the required products can be adjusted to the exact requirements of the applications in question. Prototypes for testing purposes are manufactured in small lots and at short notice.The right choice of material combined with a long-standing experience in application engineering guarantees that the joint is permanently tight even with extremely low bolt loads or unfavourable geometries, and even under the most difficult thermal and mechanical conditions.

Joint strip
Joint strip is used in expansion joints in accordance
with the materials description in Swedish building
regulations Hus AMA 72. It is also used to provide
wind-proofing and a vapour barrier.
• EPDM cellular rubber with its established benefits,
i.e. ease of use, resistance to ageing, sealing
ability, etc.
• Does not produce toxic fumes in the event of fire.
• Hollow, soft and elastic – accommodates
movements in joint.
• Made from black EPDM cellular rubber.

BLUE-GARD®
Gasketing material made from a unique blend of fibers, fillers, and a choice of several elastomeric binders. Excels in a wide range of industrial applications.
GRAPH-LOCK®
Pure exfoliated graphite material handles extreme temperatures, resists nearly all non-oxidizing chemicals, and offers excellent compressibility and low creep relaxation. Available in homogeneous material, or with metallic or non-metallic inserts.
GYLON®
Restructured PTFE gasketing with excellent chemical resistance. Significantly reduces creep relaxation problems typical of conventional PTFE.
Inorganic Fiber
Inorganic fiber gasketing with excellent thermal stability and torque retention for optimal sealability in temperatures up to 550°F (290°C) continuous.
LEAK-GARD™
Proprietary compound virtually eliminates oil and hydrocarbon leaks even under low bolt load, and avoids "weep-through" common to vegetable fiber gasketing. Recommended for lightweight gear box covers and fuel pumps, as well as standard ASME raised face flanges.
MULTI-SWELL™
Over 70% of gasket failures are due to lack of load. MULTI-SWELL™ Style 3760 Gaskets react with water or oil to create its own load. Problems with low load applications and leakage are a thing of the past.

Layers of all metal gaskets are formed into four cross-sectional profiles (round, rectangular, round with tail and double round with tail) and into a range of sizes to suite a large number of applications. Available in seven wire types: monel, tinned copper clad steel, stainless steel, beryllium copper, tinned copper, aluminium.
All metal gaskets offer excellent EMI shielding performance, providing electrical continuity when compressed between two mating surfaces.

Metex knitted wire mesh gaskets and seals provide resiliency, strength in compression, and a nearly unlimited choice of materials, constructions, or shapes for specific applications. Most important, they provide superior performance in hostile environments where other materials would fail as a result of decomposition or deformation.
Knitted mesh seals have no seams or ribs-normally the weak areas of any seal-so that when used in gasketing and sealing applications, they provide high-strength uniformity throughout the sealing area. Unlike woven or braided materials, knitted mesh consists of a continuous series of interlocking loops knitted in a tubular form, allowing two-dimensional movement in the plane of the mesh. This results in unusual flexibility and resiliency, even under heavy compression loads and exposure to extreme temperatures.

Perfect resistance.
Orobica Plast-Gom is highly experienced in elastomer technology and specialized in the production of gaskets for plate heat exchangers. Its technical division works alongside customers and designs different types of gaskets to satisfy the market, based on a simple drawing or an existing sample. All the departments are equipped with technological machinery and highly qualified staff, who first make the moulds and then the gaskets, which are vulcanized by compression or injection technology. The company is capable of making gaskets of any material, shape or size and for any type of heat exchanger. The gaskets are mounted using glue or clips. Orobica Plast-Gom also collaborates with world-renowned research labs to improve existing mixtures as well as study and test new specific elastomers. This means that it can guarantee more efficient, durable and reliable gaskets even when used in heavy-duty industrial applications, therefore cutting maintenance time and running costs.
