Abstract

An apparatus is provided for the filling and pressurisation of a tube (20) with fluid the apparatus having a high pressure connection including a shaft (1), and sealing means (11) for sealing the tube (20) when the shaft (1) is advanced into engagement with the tube (20), the shaft (1) being formed by a rod (2), a sleeve (3) located outwards of the rod (2), a rod ring (9) being connected at a forward end of the rod (2) and a sleeve ring (10) being connected at a forward end of the sleeve (3), an elastomeric sealing ring (11) is located between the rod ring (9) and sleeve ring (10). Means is provided for moving the sleeve (3) axially with respect to the rod (2) to compress the elastomeric ring (11) so that it expands into engagement with the tube (2).
