How to Join Together Two Pieces of Corrugated Flexible PVC air Hose？

Corrugated flexible PVC piping is often used in outdoor projects, or as plumbing in spas or swimming pools where there is not enough space for sturdier plumbing. Occasionally, when using these flexible PVC air hoses, you’ll have a need to connect two separate PVC air hoses. In order to do this properly — and create a water-tight seal — you’ll need a special kind of connector designed for this purpose.
Things You’ll Need
-Flexible connector for corrugated PVC air hose
-Flat-blade screwdriver

Insert the end of the first piece of PVC air hose into one side of the flexible connector. If the connector is of the appropriate size, the PVC air hose will squeeze in without an excessive amount of force. If you need to crimp or bend the PVC air hose in order to force it in, use a larger connector.
Insert the end of the second piece of PVC air hose into the other side of the flexible connector.
Use your flat-blade screwdriver to tighten down the clamps on both ends of the connector. Continue tightening until the resistance makes it difficult to turn the screws anymore. This will create a water-tight seal on the PVC air hose.
