ABSTRACT:
A syringe assembly includes a syringe receiving a plunger at one end and at the other end there is an extended part which can be heat deformed to hold a ported cap member and a rotatable valve member to the syringe. The ported cap member includes ports adapted to be connected to tubes for receiving, or conveying fluid material. The ported cap member has a central opening through which the extended part extends. The rotatable valve member is located between the syringe and the ported cap member for sealingly engaging both the syringe and the ported cap member by O-ring seals therebetween. The ported cap member is non-rotatably connected to the syringe by a splined connection.
