Suitable for drains with diameters of 31–40 mm and sinks with a sink opening diameter of 35 mm. What makes it stand out Combines shape flexibility and sealed connections so you can adapt to irregular plumbing runs without sacrificing a tight, reliable seal. Simple range of adjustment (19–59 mm) covers common installation gaps while the S-bend function protects indoor air quality. Practical uses / applications Kitchen sink replace or retrofit: Adjust the pipe into an S-bend or U-bend under a kitchen sink to match existing drain plumbing while preventing smells and insect ingress.

Retrofit or repair under-sink plumbing: Replace damaged rigid traps when wall or floor drain positions differ from the sink outlet.
