Constructed from dezincification-resistant brass, a specialty alloy that is designed for closed cooling water circuits, these fittings are guaranteed to have a long life and functionality. Additional safety is achieved by durable FKM-sealings (Viton). LIQUIDLINE threaded connections and push-in fittings for cooling water withstand aggressive watery liquids and many other substances. They are resistant to high and low temperatures.

These fittings are Available in 6 mm or 8 mm OD configurations for 6 mm or 8 mm OD tubing, respectively.

Each package comes with 2 Eisele Liquid Fittings.


  • The mass of one 6 mm straight fitting is 11 grams. The mass of one 8 mm straight fitting is 17 grams. The mass of one 6 mm elbow fitting is 24 grams. The mass of one 8 mm elbow fitting is 42 grams. 

  • The compression side should be hand tightened. The threaded side should be torqued to a maximum of 9 Nm for a proper seal.

  • If using these compression fittings with a tube material that has a Durometer of 95A or softer, a tube support will be necessary in order to properly secure the tube within the fitting. An example of a tube support for the 6 mm fittings can be found here and a tube support for the 8 mm fittings can be found here.

  • If using a tubing softer than 95A, we tested and recommend Viton® fluoroelastomer tubing with a Durometer of 75A. Here is a link to the 6 mm OD tubing and here is a link to the 8 mm OD tubing.
