Sliding Ducts

Sliding Pipes

Sliding ducts (or telescope fittings) allow to adjust the length of standard tubes and to bridge eventual gaps. They are also useful when straight ducts with parallel flanges have to be shortened on the building site.

  1. Sliding Duct (L: 250 mm)
  2. Standard METU-FORM duct with parallel flange (to order separately)
  3. O-Ring made of NBR
  4. SRX Joining Clip
  5. Formed-on parallel flange


When installed vertically, each duct segment must be individually fixed and secured!
