PURPOSE: An air-conditioner pipe sleeve is provided to install a sleeve indoors and inject sealant when the sealant is applied on the exterior wall of a high building, thereby sealing an opening. CONSTITUTION: An air-conditioner pipe sleeve comprises a cylindrical tube(10), a circular ring(20), a nut(30), a compression cap(40), and a nozzle(50). The cylindrical tube is manufactured of plastic materials. A groove is formed on one end of the cylindrical tube and a screw thread is formed on other end. The circular ring is inserted into the groove of the cylindrical tube. The nut is coupled with the screw thread of the cylindrical tube. The compression cap seals between the wall of the cylindrical tube and the nut. |
