How to choose
- Thread size: choose 3/8", 1/2", 3/4" or 1" to match the connection. Check whether the thread is internal or external in the product drawing and dimensions table.
- Length: the L-10 to L-100 designation indicates the extension length. Choose the length according to how far the connection needs to be brought forward.
- 6K12, 6K13.5, 6K14 designation: these designations appear on 1/2" sizes. For 6K12 and 6K14, the drawing specifies 12 mm and 14 mm hexagons respectively, so check your spanner size and the available installation space.
- Operating parameters: brass, maximum working pressure 10 bar, operating temperature 5-95°C. Make sure the installation operates within these limits.
- Water meter applications: for installation with a water meter, choose extensions whose name specifies that they are intended for a 3/4" (DN 20) water meter.
Typical applications
Extensions are used where a water outlet or fitting connection needs to be brought forward past a wall, cladding or other finishing material. Short versions, such as L-10 or L-15, compensate for small differences in depth. Longer versions, up to L-100, allow the connection to be brought forward by a greater distance. Water meter versions are used in installations with a water meter.
