An endoscopic assembly for an endoscope, the assembly comprising: a barrel having proximal and distal portions (14, 15), the proximal portion having a seat and a receiving wall extending to a proximal end, the receiving wall having a first threaded portion formed thereon; and a connector for connecting the barrel about the endoscope, the connector having a scope portion and a tip portion, the scope portion having a receiving end through which the endoscope is disposed to engage the seat for connecting the barrel about the endoscope, the tip portion having a second threaded portion formed thereon, the second threaded portion being configured to cooperate with the first threaded portion to attach the connector with the barrel, the first and second threaded portions (30, 42) being configured to cooperate with each other to tighten the connection of the barrel about the endoscope as the threads (30, 42) increase surface area contact therebetween; characterised in that a gasket is disposed on the seat and within the receiving wall of the barrel, wherein the gasket engages the receiving wall and is configured to receive the endoscope, the gasket having an inner diameter, and being configured to be collapsed when the first and second threaded portions (30, 42) tighten the connection of the barrel, wherein the connector and the barrel are configured to cause the endoscopic assembly to axially compress the gasket between the seat and the tip end, thereby reducing the inner diameter to press fit onto the endoscope, wherein the required number of turns of the barrel on the connector depends on the size of the outer diameter of the endoscope to be received. a barrel having proximal and distal portions (14, 15), the proximal portion having a seat and a receiving wall extending to a proximal end, the receiving wall having a first threaded portion formed thereon; and a connector for connecting the barrel about the endoscope, the connector having a scope portion and a tip portion, the scope portion having a receiving end through which the endoscope is disposed to engage the seat for connecting the barrel about the endoscope, the tip portion having a second threaded portion formed thereon, the second threaded portion being configured to cooperate with the first threaded portion to attach the connector with the barrel, the first and second threaded portions (30, 42) being configured to cooperate with each other to tighten the connection of the barrel about the endoscope as the threads (30, 42) increase surface area contact therebetween; characterised in that a gasket is disposed on the seat and within the receiving wall of the barrel, wherein the gasket engages the receiving wall and is configured to receive the endoscope, the gasket having an inner diameter, and being configured to be collapsed when the first and second threaded portions (30, 42) tighten the connection of the barrel, wherein the connector and the barrel are configured to cause the endoscopic assembly to axially compress the gasket between the seat and the tip end, thereby reducing the inner diameter to press fit onto the endoscope, wherein the required number of turns of the barrel on the connector depends on the size of the outer diameter of the endoscope to be received.
