Abstract:
@ The ends of flexible plastic tubes (20), particularly of relatively thin wail thickness, are closed with a cylindrical header (10) of end plug over which an end of the plastic tube (20) is fitted. A fluids tight connection between the wall of the plastic tube (20) and the cylindrical header (10) or plug is made by press fitting over the connection area a plastic ring (25) smaller in diameter than the outside diameter of the plastic tube (20) within the elastic limit of the plastic ring (25). Preferably the header (10) and/or end plug have circumferential grooves (13) or depressions into which groove (13) or depression the wall of the tube (20) is fitted or depressed, preferably by multi-turns of plastic thread (21). For corrosive and oxidizing environments the header (10), plug, plastic tube (20), sealing rings and depressing thread (21) are composed of perfluorocarbon polymers.
