Abstract
A flared tube fitting for mechanically connecting fluid transmission lines includes one or more diametrically guided and sealed pistons to engage the flared tube connection. These pistons are axially spring loaded and designed to apply a hydrostatic pressure force upon the engaged tube flare connection independent of the clamping force applied by the axially preloaded threaded engagement of the flared tube fitting to the nut member in which the flared transmission line is supported. In the tube connection with a conventional flare tube fitting, the loss of the clamping force of the preloaded threaded engagement will result in the separation of the flared line from the conically shaped end of the flared type fitting. External leakage will occur. In the tube connection of the present invention, the sealing contact at the flared connection will be maintained by the spring and hydrostatic pressure forces on the engaged piston should the clamping force of the preloaded threaded engagement of the nut member be removed.
