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.

Installation

1. At the time of installation, the sealing surface must be clean, free from grease and dry to enable the gasket to stick properly.
2. The width of the joint gasket is to be determined by the nominal diameter or type of flange.
3. 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.
4. Remove the protective foil from the adhesive joint gasket to allow for fitting.
5. Stick the gasket about 2mm away from the bolt hole and press lightly.
6. Do not butt the ends, instead overlap them in front of a bolt.
7. Tighten the lubricated bolts in opposite pairs. The lap joint deforms perfectly to give a reliable seal.
8. On irregular of damaged flanged surfaces, it is possible to build up with short length of ePTFE FLEX-O-SEAL.
