ABSTRACT:
An inlet includes a bottom assembly and a top assembly. The bottom assembly includes at least one male unit, and the top assembly has at least one beveled surface and includes at least one female unit and a lateral driving unit. The top assembly is placed inside the bottom assembly by aligning the female unit of the top assembly with the male unit of the bottom assembly. The lateral driving unit laterally drives the top assembly and causes the beveled surface of the top assembly to rise against the male unit of the bottom assembly, allowing the top assembly to seal with the bottom assembly.
