Piping and wiring sleeves

Abstract

This product is a piping and wiring sleeve for guiding piping and wiring from indoors to outdoors when installing an air conditioner. Specifically, when installing an air conditioner, it is inserted into a through-hole in the wall separating the inside and outside of a house, and connects the indoor unit to the outdoor unit by passing refrigerant pipes, drain hoses, electrical wires, etc. through it. By deforming the bellows, the flange can be angled, allowing it to be installed without gaps even in an inclined through-hole that allows drain water to flow outdoors.
