## Long description

VIEGA reducer fitting Viega 2315.1 is a stainless steel pipe reduction designed to join pipes with diameters of 42 mm and 35 mm. Supplied in a pack of five, this reducer provides a compact, form-fit transition for plumbing, heating and industrial piping systems where a reliable connection between dissimilar pipe sizes is required. The stainless steel construction offers corrosion resistance and mechanical strength suitable for potable water, heating circuits and other non-corrosive media.
Advantages
The stainless steel construction ensures long-term resistance to corrosion and mechanical wear while maintaining dimensional stability under typical operating temperatures in domestic and commercial plumbing systems. The 42x35 mm diameter transition allows straightforward adaptation between two commonly used pipe sizes without extensive rework. Supplied as a set of five fittings, the pack supports multiple connections or small installation projects and reduces handling time compared to single-piece purchases.
Suitable for
 Connecting 42 mm to 35 mm pipes in potable water supply systems
 Integration in heating circuits and radiators where size reduction is needed
 Industrial piping with non-aggressive media requiring stainless steel components
 Repair and retrofit work where existing lines use mixed pipe diameters
When it may not be suitable
This reducer is intended for use with compatible stainless steel or otherwise approved pipe materials and jointing methods; it may not be suitable where the system requires specialized coatings, non-stainless metals, or highly aggressive chemical media. For applications involving extreme pressures, unusual temperatures, or non-standard connection types, verify compatibility with system specifications and applicable standards before installation.
Key specifications
 Material: stainless steel
 Connection sizes: 42 mm → 35 mm
 Pack quantity: 5 pieces
 Typical application: water supply, heating, industrial piping
How to use
Select the reducer matching the pipe outer diameters and the jointing method used in your system (e.g., press-fit, soldering, or mechanical coupling) and prepare the pipe ends by cutting square and deburring. Assemble the fitting according to the manufacturer’s recommended installation technique for stainless steel components and the chosen joining method, ensuring correct alignment and secure connections. After installation, perform any required pressure or leak tests in line with local codes and project specifications.
What to consider before purchase
 Verify that pipe materials and wall thicknesses are compatible with stainless steel reducers and the intended joining method
 Confirm operating pressure and temperature ranges of the system match the fitting’s suitability
 Ensure the 42x35 mm transition suits the existing pipe sizes to avoid additional adapters
Usage recommendations
Use appropriate installation tools and follow Viega or system-specific guidelines for stainless steel fittings; where required, consult a qualified installer to ensure correct jointing and compliance with local plumbing and heating regulations.
