<p>In an assembly comprising a plastic lined hose (12, 13b) having secured to an end thereof a hollow end fitting (20) having a spigot and a sealing face, wherein the spigot is located between the hose and the liner, the sealing face has a groove (20c) therein and the liner end passes through the end fitting and is flared out to form a plastic sealing face overlying the sealing face of the end fitting. The assembly is then processed to cause the flared sealing face of the liner (13b) to assume the same shape as the underlying recessed sealing face of the end fitting (20) , such that the plastic sealing face may then be clamped against the sealing face of a mating end fitting (14) using a standard "beaded" rubber seal (22) and a clamp ring (16). Advantages include concentric location, lower clamping forces and avoidance of any entrapment zone. <IMAGE></p> |
