    Is it okay to use corrugated tubing for pigtail connections How do I connect it

    If you need to connect multiple corrugated tubes, use specialized connectors or couplings for the connection. Ensure that the connections are sturdy and reliable, and have good sealing performance. 1 Applications. Pipes made of corrugated flex copper were popular about 30+ years ago, in particular they were used to connect stop valves and bathroom/kitchen faucets, as shown in the photo. Even though these are usually rigid materials, convoluted plastic tubing becomes flexible. Corrugated conduit is a type of protective tubing with a ribbed, flexible design used to route and safeguard electrical wires and cables. The cable bundle is placed inside the pipe, which protects it from damage.
