FRIALEN safety fittings can be fused with SDR11 - SDR17.6 pipes, minimum wall thickness s minimum ≥ 3 mm. Other levels of SDR can be processed on request. Please note the mandatory labels directly on the product. DVGW test mark issued: DV-7501AU2256

Areas of Application

The FRIALEN-Transition Fittings USTN are threaded joints as an adaptor from a metal pipe with threaded socket to a HD-PE pipe. Joint on the part of HD-PE by FRIALEN-Coupler.

Assembly Instructions

The threaded component must be held with a spanner to prevent it twisting in the HD-PE component. The fusion of the HD-PE side takes place by FRIALEN-fusing – leakproof and longitudinally strong. The installation of the steel and the HD-PE side has to be prepared according to the general installation instructions (see ”Transition Fittings with threaded connection” in ”Assembly Instructions” for ”FRIALEN-Safety Fittings for house connections and distribution pipes up to d 225”). This involves removing the oxide skin and cleaning the pipe ends.

Good reasons for using the FRIALEN USTN:

  • Compact construction

  • HD-PE side with exposed heating element for optimal heat transfer

  • Cold zones at the end to prevent the flow of molten material

  • No holding clamps required

  • Large insertion depth, extra wide fusion zones

  • Steel end permanently anchored in the HD-PE and will not distort

  • Self sealing patented sealing geometry without elastomer seal

  • Additional barcode for tracing back the fitting (Traceability-Coding)
