PTFE Profile TF1

FLAT SEALING STRIP

Despite its high level of breaking and tensile strength, the gasket remains soft and supple and is perfect for smooth­ing out uneven areas on the sealing surface.

The strip is stretched using a special technique that allows the material to retain its individual properties.
The glue strips attached to one side serve as aids for easy fitting of the strip during installation.

The use of the PTFE strip as a permanent replacement for flat gaskets, such as those required by DIN 2690, is not recommended.

Flat sealing strips made from pure graphite are available at 98 % carbon quality and at nuclear quality of 99.85 % carbon. They can be supplied in a smooth or corrugated roll. The strips are manufactured with an adhesive backing.

The width of the strips ranges from 6 mm to 70 mm. The usual lengths are 10; 12; 15, 47 and 50 meters. Other lengths are available on request.

Depending on the circumference, the strips are delivered in plas­tic cans, in cartons or skin-packed onto cardboard.
The thickness of the pure graphite strips is 0.38 mm; 0.5 mm; and 1 mm. The density of the 0.5 mm and 1 mm strips is 1.0 g/cm³. The strip with a thickness of 0.38 mm has a density of 1.1 g/cm³.

Pure graphite strips

• have excellent gliding properties
• a chloride content of less than 50 ppm
• are self-lubricating
• have outstanding heat-conducting properties
• contain no adhesive agent or filler
• are physiologically harmless

Self-sticking pure graphite strips are useful when fitting strips on hard-to-reach positions.

If a punched pure graphite gasket is not available as a clad­ding for metallic gaskets, e.g. grooved gaskets, then a self-adhesive pure graphite strip can be used. Depending on the width of the strip, the corrugated strip can also be used for small radiuses.

Pure graphite strips can also be used to seal spindles. For this, the strip is wound around the stem, so that it can then be pressed into the gland area by the gland flange

WWe also supply pure graphite strips as pre-compressed rings. Seethe section entitled “Packings”, RivaTherm Packing K80.
