A method of securing an end fitting ( 10 ) to an end of a hose ( 12 ) having an outer braid ( 12 a) and a plastic liner ( 12 b) is disclosed, the method including the step of: i) providing a hollow end fitting ( 10 ) for a hose ( 12 ), the end fitting ( 10 ) having a spigot ( 10 a) and a sealing face; ii) inserting the spigot ( 10 a) of the end fitting ( 10 ) between the braid and the liner( 12 b) and bring the liner end through said hollow end fitting ( 10 ) and flaring out the liner end to form a plastic sealing face; iii) processing the assembly so formed in such a manner as to cause the flared liner end to form a shape which includes a bead ( 26 ) on the liner surface and which has its inside edge ( 28 ) squared off. The bead ( 26 ) is preferably concentric and allows the rubber seal previously used to be dispensed with. The end fitting ( 10 ) preferably comprises a PTFE lined end fitting, in which the PTFE hose liner ( 12 b) is passed through the bore of the end fitting ( 10 ), and is then flared out. A plastic lined hose ( 12 ) is also disclosed having secured to an end thereof a hollow end fitting ( 10 ) having a spigot ( 10 a) and a sealing face ( 10 b), wherein the spigot ( 10 a) is located between the braid ( 12 a) and the liner( 12 b), and the liner end passes through the end fitting ( 10 ) and is flared out to form a plastic sealing face overlying the sealing face ( 10 b) of the end fitting ( 10 ) to form a shape which includes a bead ( 26 ) on the liner surface and which has its inside edge ( 28 ) squared off. |
