## Summary description

Copper reducing coupling VIEGA 35–28 mm (model 105334) for joining copper pipes of different diameters. Designed to connect a 35 mm pipe to a 28 mm pipe, it provides a durable metallic transition fitting for plumbing and heating systems. Suitable for potable water, radiators, and general copper pipe installations where a secure reduction is required.

## Long description

Copper reducing coupling VIEGA 35–28 mm 105334 is a metallic pipe fitting designed to join copper pipes of different diameters. It provides a secure, permanent transition between a 35 mm and a 28 mm copper tube and is suitable for plumbing and heating installations where a reduction in pipe size is required. The coupling is made to meet the mechanical and corrosion-resistance demands typical for potable water and radiator systems and offers reliable performance in standard installation conditions.
Advantages
The coupling delivers a compact, solid mechanical connection that maintains flow integrity between different pipe sizes without the need for additional adapters. Constructed from copper-compatible materials, it supports safe use with drinking water and heating media and is resistant to typical domestic plumbing stresses. Its simple geometry allows for straightforward installation in confined spaces and ensures stable, long-term service when assembled according to standard plumbing practice.
Suitable for
Reducing a 35 mm copper water main to a 28 mm branch in potable water systems
Connecting radiator feed or return pipes of different diameters
General copper-pipe reductions in residential and commercial plumbing
Retrofitting or repair works where a durable metallic reduction is needed
Key specifications
Material: copper-compatible metallic construction suitable for copper tubing
Nominal sizes: inlet 35 mm, outlet 28 mm
Application: potable water and heating systems
Connection type: fixed reducing coupling for copper pipes
Operating environment: indoor plumbing and heating installations
How to use
Prepare both copper pipe ends by cutting square and deburring the inner and outer edges. Clean the pipe surfaces to ensure good contact and remove oxides where necessary. Slide the coupling onto the larger pipe end and insert the smaller pipe fully into the opposite side until the pipes seat against the internal stop. Secure the joint according to accepted practice for metallic copper couplings—this may include soldering, brazing, or using the manufacturer’s recommended joining method when applicable. After assembly, inspect the fitting visually and pressure-test the circuit to verify leak-tightness before putting the system into regular operation.
Usage recommendations
Use compatible joining methods and follow local plumbing codes. Ensure correct pipe preparation and proper heat control if soldering or brazing. For potable water systems, verify material suitability and cleanliness during installation. When working near heat-sensitive materials or insulation, protect surrounding components from excessive heat. If in doubt about the correct joining technique, consult a qualified plumber or the manufacturer’s installation guidelines.
