Extension spindle for service connection valves, DVGW 336 for water, neutral liquids and gas

AVK telescopic extension spindles are designed for ease of use and long service life. The two fixation lugs can be attached to AVK surface boxes, a lock spring prevents the telescopic part from collapsing during installation, and a defrosting hole enables insertion of a heating element. The extension spindles are made of corrosion-free materials and the centre sleeve and bottom cover protect against penetration of impurities.

Variant 04/F-004
Material: Polyethylene (PE)
DN: DN25 - DN50


  • The top adaptor has a defrosting hole intended for insertion of a heating element to prevent freezing of ground water inside
  • The two fixation lugs can be attached to AVK surface boxes and support tiles
  • A lock spring prevents the telescopic part from collapsing during installation, as it creates friction inside the inner square tube
  • The center sleeve protects against penetration of impurities between the two outer PE pipes
  • The inner tube is press fit to the top spanner and bottom adaptor to safeguard the galvanization of the tube
  • The bottom cover protects the valve spindle from sand and dirt and enables it to rotate freely
  • Patented and fast “Safe-click” mounting by fixing the spindle adaptor to the valve stem with a split and turning the bottom adaptor until a “click” indicates fixation to the valve bonnet
  • Available in 5 different lengths
