Reducer/Transition WADEX REDUCTION WK 140/150 — pipe coupling from 140 mm to 150 mm

WADEX REDUCTION WK 140/150 is a pipe reducer designed to connect pipes with nominal diameters of 140 mm and 150 mm. The coupling provides a tight transition between different pipe sizes, suitable for drainage, sewer and ventilation systems where a change of diameter is required. Made for installation, repair and modification of plumbing and HVAC piping, the reducer ensures alignment and secure joining of pipes while maintaining flow continuity.

Advantages

The reducer offers a simple mechanical solution for adapting pipe diameters without complex fittings. Its precise dimensions provide reliable sealing and alignment between 140 mm and 150 mm pipes. The design reduces installation time and minimizes the need for additional adapters or custom cutting. Materials and construction are selected to withstand typical loads, pressure variations and environmental conditions in drainage and ventilation applications.

Suitable for

• Connecting drainage pipes of different nominal diameters
• Adapting sewer piping during repair or renovation works
• Transitioning ducting in ventilation systems where a small diameter change is needed
• Temporary or permanent joins in residential and light commercial plumbing

Key specifications

• Connection sizes: 140 mm to 150 mm nominal diameters
• Function: concentric reduction/transition coupling
• Application: drainage, sewerage and ventilation systems
• Compatibility: for pipes with matching nominal diameters and socket/profile types
• Installation type: push-fit or socket connection depending on pipe system

How to use

Ensure both pipe ends are clean, free of debris and correctly aligned. Insert the smaller or larger pipe end into the corresponding side of the reducer so that the coupling sits evenly over the joint. Apply the recommended sealing method for the pipe system in use (rubber gasket, sealant or adhesive) and verify alignment before final tightening or securing. After installation, check the connection for leaks under normal operating conditions and make adjustments if necessary.

Usage recommendations

Use the reducer only with compatible pipe materials and profiles. Verify that the nominal diameters and socket types match before installation. For systems subject to high pressure or aggressive media, consult the pipe manufacturer’s instructions and consider additional sealing or mechanical support. Inspect joints periodically for signs of wear or leakage.
