TOPSEAL (12 m x 12 mm x 0.10 mm). HD. (density: 1.3 g/ cm3). Tested by BAM for liquid oxygen. Ideal for use in situations where there are high requirements for e.g. acid-resistance, pressure or heat. This product is very diffusion-proof and is therefore highly suitable for oil, petrol and diesel. APPROVED for gas and drinking water (EN 751-3 and DIN 30660). Otherwise same use as for other high-density tapes. Temperature resistant from -200°C to +260°C.

Thread seal tapes from Unipak are white, non-adhesive thread seal tapes produced from pure Polytetraflourethylen (PTFE).



Multitape and Topseal is used for sealing of threaded joints on installations with especially oxygen, while Sealrite may be used on all types of installations with gas and lager threads.
The types of tape described here are applied for the sealing of threaded joints on systems for water, compressed air, cooling and steam systems and hydraulic systems. Applicable on all types of materials (iron, metal, plastic, fibre etc.). Thread seal tape is also suitable on systems where heavy hygiene requirements are made (hospitals, food industry etc.) Topseal/Multitape/Sealrite is suitable for about all tubing materials like iron, stainless steel, cast metals, plastics, fibre etc. Sealrite is because of its thickness not so suitable for smaller threads.



The exceptional strength and high molecular weight of the carbon fibre-fluorine compound provides PTFE-tape series of outstanding qualities. Temperature proofed from -200°C to +260°C depending on the density of the tape. On installations with a working temperature higher than 90°C we recommend to use tape with a density of 1g/cm3 or more. PTFE-Tapes are resistant to almost all types of acids, bases, solvents, chemicals etc., however, with the exception of fluorine, some fluoride chemicals and melted alkali metals. Very low coefficient of friction. Non-inflammable (ASTM D-635 og D-470). Non-ageing. High tensile strength even at low temperatures. Breaking-down resistant, especially, in connection with bending and vibrations. Sound electric insulating power independent of frequency and temperature.



Remove any dirt and metal shavings from the thread before application of PFTE-tape. Put the tape on the thread joint in the direction of inclination of the thread. Apply the tape with an even, firm pull to be tight fitting about the thread. Dependent on wanted thickness of layer the overlap should be from ½ to ¾ tape width. Using High-Density tapes approved for gas - like Multitape/Topseal/Sealrite - it is possible to turn back the assembled joint with 45º or more. The tape is used alone and without any use of sliding agents.
The information above is given on the basis of tests and experiences. However, since we have no knowledge about all details in the final use of the product we recommend a trial installation to ensure that the specification of the product matches the physical demands.



TOPSEAL is approved for all types of gas as well as for liquid and gaseous oxygen and drinking water. TOPSEAL is also approved by BAM for liquid and gaseous oxygen.
