ABSTRACT:
An apparatus for the pressure testing of tubing has two support members which can be urged towards one another, one of which forming a counterbearing for the tubing and the other having a spigot with a conical face which is at least partially insertable in one end of the tube under test to seal it. The support member with the spigot is connected to an actuating spindle which is coaxial with the axis of the spigot and between the actuating spindle and the support member there is a pressure drive including a cylinder and a piston which is connected in tandem with the actuating spindle to bring the spigot into engagement with the tube. The spigot has a duct through which a test medium can be introduced into the tubing.
