Applications:
chemical industry, pulp and paper, petrochemical, pharmaceutical, food industry (including production of alcohol), heat and power genera-tion, machine building, vessels, water pipelines, potable water station, technical gases including oxygen, gaskets used in valves, machines, heat exchangers in both power engineering and chemical installations, pipelines, especially made from plastic, glass, rubber coated and other, in reactors, destillation columns, tanks and containers. In all applications where low seating load is required, excellent tightness, high mechani-cal resistance to relaxation, physiological properties, chemical resistance but at low and medium pressures; SPETOFLON® TEX BG tape th. 2, 3 mm. is also considered as a universal sealing solution for mainteinance personnel.

SPETOFLON® TEX FGR-F is manufactured by pre-forming SPETOFLON® TEX FGR gasket which reduces the active se-aling area on one hand, on the other, closes the paths between anti-difusion zones, this version is designed for the rigid flanges e.g. from epoxy-yarn composite and similar; gasket’s sealability is not affected by the load changes; ad-ditionally, easily formable in the irregular flange faces; Gore-Tex Tri-Guard gaskets available as an alternative.

SPETOFLON® TEX FGR-J gasket composed of the corrugated 316L stainless steel ring (other materials on agreement) and two layers of SPETOFLON® FGR (Gore Tex GR as an option); thanks to the corrugated metal ring the gasket has improved recovery, strength, resistance to relaxation and blowout; it is a gasket highly recommended for dangerous media (toxic, explosive, etc.); it is necessary to choose the metal compatible with the sealed medium.

|
SPETOFLON® TEX FGR-H is composed of the core made from sintered PTFE and two layers of SPETOFLON® FGR; such desing reduces active area of the gasket, therefore it can be installed with low assembly loads, e.g. in epoxy-fi-bre composite flanges; due to PTFE core other materials are not introduced and exposed to the sealed medium; ga-sket is a very economical solution and is able to seal irregular flange surfaces.

|
SPETOFLON® TEX FGR R is a sealing sheet and gasket manufactured from multi-directionally oriented expanded PTFE; in order to improve installation properties, the sheet is harder and has higher density, which is important whi-le installing the gaskets in the vertical flanges, especially in case of medium and large diameters; Gore-Tex GR-R sheet available as an alternative.

|
SPETOFLON® TEX FGR material and gasket manufactured from multi-directionally expanded PTFE in a proprietary technology; easily formable material, easy to cut by means of the simplest toos, may be used as a universal sealing material; Gore-Tex GR sheet available as an alternative.
