Champion ePTFE Universal Rope Gasket is a specially formulated sealing (un-sintered) made of 100% expanded PTFE that withstandsvibration, wide operating temperature range and has extremely low coefficient of friction. The friction free characteristics promote Smoother action and increases the life ofthe gasket many times over.It is used as a gasket in flanged connections, pressure vessels and other similar mating faces as well as packing for valves and similargland applications. The recommended temperature for PTFE universal gasket is upto +260°C.
Application: PTFE universal rope gasket is suitable for pumps,valves and many other static applications. Due to the chemicalinertness of PTFE, it can be used with all substances. It offers excellent sealing when used in place of gasket or jointing in flanges in almost all type of industries.

Specifications:

Expanded PTFE Sheet material is capable of a wide service range in applications found throughout process industries. The UFG multilayer manufacturing method provides reliable sealability due to the low stress and exceptional dimension stability characteristics the material possesses. This form of gasketing material is processed by expanding 100% pure polytetrafluoroethylene (PTFE) into a highly fibrillated, bi-directional, soft, compressible gasket for longer life and trouble free sealing. Its form-in-place versatility is perfect for flange surfaces that are worn, warped or scored.
The distinct compressibility of the UFG gasket enables it to effectively fill flange imperfections for a tight, leak-free seal. Unlike conventional PTFE materials which are prone to cold flow, EPTFE has good creep resistance and bolt torque retention properties.
The EPTFE material has excellent chemical resistance with a pH range of 0 to 14, making it suitable for most medium. The temperature service parameters range from -450°F (-268°C) to 500°F maxiumum/600°F spike (260°C/315°C) and pressure ranges from full vacuum to 3,000 psi (206 bar).
These exceptional values are achieved without the need of filler materials like silica, barium sulfate or hollow glass spheres.
The EPTFE material is ideal for both high load metal flanged applications and low load applications such as glass-lined steel, glass and FRP (fiberglass reinforced plastic) piping and vessels.

Other Details:

• High adaptability, suitable for flanges with corrosion and with uneven sealing surface.
• Ideal for use with more fragile piping systems.
• Easy to install and remove, anti-sticking for effortless flange surface cleaning.
• No embrittlement of the gasket in storage or in service.
• FDA certified.
• Impermeable.
• Chemically inert.
• High temperature and pressure.
• Seals at low stress loads.

Champion PTFE Flex-O-Seal is a unique sealing material manufactured from special grade of 100% expanded pure PTFE by transforming into a fibrous structure. ePTFE Flex-O-Seal has a special peel off adhesive on one side. Though very tough, our ePTFE Flex-O-Seal is soft and suited to all types of flanges, covers and narrow cavities. Due to its soft and flexible structure this rope gasket is an ideal seal under pressure, without significant cold flow even on irregular, badly damaged or corroded flange surfaces. Once bolted this gasket rarely needs to be re-torqued. CHAMPION ePTFE FLEX-O-SEAL is easy to install and is able to fill in severe surface irregularities. The flexible applications of this product allows reduction of inventory of ready made gaskets/envelopes, thereby the term Universal Joint Gasket.
Other Details:

• Sealing surface must be clean, free from grease and dry to enable the gasket to stick properly.
• The width of the joint gasket is to be determined by the nominal diameter or type of flange.
• Selection of a tentative size of joint gasket would be approx, 1/3rd flange contact width inside the bolt hole; example: 7 mm gasket joint to suit a 20mm flange width.
• Remove the protective foil from the adhesive joint gasket to allow for fitting.
• Stick the gasket about 2mm away from the bolt hole and press lightly.
• Do not butt the ends, instead overlap them in front of a bolt.
• Tighten the lubricated bolts in opposite pairs. The lap joint deforms perfectly to give a reliable seal.
• On irregular of damaged flanged surfaces, it is possible to build up with short length of ePTFE FLEX-O-SEAL.

Application:
ePTFE FLEX-O-SEAL is safely used in applications on oil rigs, petroleum refineries, offshore operations, corrosive chemical processing, food processing, paper mill, marine installation, in glass lined or fibre glass reinforced vessels and tank lid sealing, heat exchangers, manhole covers, vent pipes, pumps or compressors housing flanges, valves and many other industrial applications where the use of a conventional pre-cut gaskets is not suitable or readily available.
