<p>The fluid having a height lower than 2 mm. The material is steam-tight with a thickness of 0.6-1.5 mm and permeability lower than 40g/m 2>/72h. Rigid tubular end (17) inserted inside the tube and crimping ring is placed on the protection layer and rubber sleeve tightening element. The element forming an elastic reserve, which is placed between the ring and protection layer/between the tubular end and the tube. The polyamide is chosen from polyamide 6 and polyamide 6.6. The element having a thickness of 1.5-2.5 mm. The protection layer (7) is made from a thermoplastic elastomer e.g. EPDM/PP, NBR/PP, IIR/PP, TPU, especially Vegaprene. The tube (3) has a thickness of 0.5 mm and is a multi-layer tube and/or treated with plasma. An independent claim is also included for an air-conditioning circuit.</p> |
