This is the Pingel version of the vacuum line from intake #6.
Very few people have the Pingel 1311.
The product is made of two sizes of Viton B tubing, joined with a Kynar laboratory grade fitting. There is Teflon PFA tubing inside each of the Viton B tubes for support under vacuum. The smaller tubing clamp is Happy Fingers style (loops on the ends to keep from puncturing your fingertips) and the clamp on the bigger tube is called a band clamp. This vacuum line is designed to work for many years under hot conditions, and can be disconnected and reconnected as many times as you want, like for example every time you pull the tank to replace the air filter.
