Abstract
PVC hose for gas is used widely in many of places which is used for connector between combustor and gas cock. In this study, it is collected by 5 regional area as Gyeonggi, Jeonnam, Gyeongbuk, Jeju and Gangwon and tested in leakage, hardness, anti-low temperature. As a result, the color on it is started to change rapidly when it is installed. Some of specimen are broken in bending test after keeping in $-25^{\circ}C$, 24hours. It's hardness has a tendency to increase gradually. If hardness of hose is increased, PVC hose is separated easily from cock or combustor so that LP gas or city gas can be escaped. For prevention of gas leakage accidents of PVC hose, the available period of it should be presented.
