Reducer coupling No name REDUKCJA 32/40/50 PROSTA R 345 – pipe reducer 32/40/50 mm

Straight reducer coupling REDUKCJA 32/40/50 PROSTA R 345 by No name is a compact stepped pipe reducer designed to join pipes or fittings with diameters of 32 mm, 40 mm and 50 mm. The single-piece straight design provides a stable transition between sizes for plumbing, HVAC and ventilation systems, allowing fluid or air flow to be routed through connections that require distinct diameter changes in a confined space.

Advantages

The straight reducer coupling delivers a reliable, space-saving solution for connecting three common pipe diameters without separate adapters. Its one-piece construction reduces potential leak points compared with multiple couplings and simplifies installation. The stepped profile ensures clear size transitions while maintaining a straight alignment of the pipeline, which helps preserve flow characteristics and reduces stress on adjoining fittings.

Suitable for

• Plumbing systems requiring transitions between 32 mm, 40 mm and 50 mm pipes
• HVAC and ventilation ducting with stepped diameter connections
• Retrofit or repair work where a compact, fixed reducer is needed

Key specifications

• Material: suitable for common plumbing and ventilation materials (verify compatibility with system material)
• Connection type: straight stepped reducer with three diameter levels
• Compatible pipe diameters: 32 mm, 40 mm, 50 mm
• Design: single-piece, straight profile for inline installation
• Intended use: fluid and air systems where a fixed reduction is required

How to use

Choose the appropriate end of the reducer for the respective pipe diameter and ensure pipe ends are clean and free of burrs. Insert pipes fully into the corresponding stepped sections and secure them according to the piping system requirements — for example with clamps, solvent welding, adhesive or mechanical couplings as compatible with the pipe material. Verify alignment to maintain a straight pipeline and test the joint for leaks or air tightness before putting the system into regular operation.

Usage recommendations

Confirm material compatibility with the existing pipes and the transport medium (water, air, other fluids) and ensure the reducer is installed in accessible locations for inspection. Avoid applying excessive torque during assembly and follow system-specific joining methods to maintain a durable, leak-free connection.
