## Summary description

Soldered reducing coupler by VIEGA, model 115852, with connection sizes 54 mm to 35 mm. Designed for joining copper or compatible metal pipes where pipe diameter must be reduced. Provides a permanent, leak-resistant joint after soldering and is suitable for heating, plumbing and industrial fluid systems requiring a reliable reduction in pipe size.

## Long description

VIEGA reducing soldered coupler 54 x 35 mm, model 115852 is a metal pipe fitting designed to join a 54 mm pipe to a 35 mm pipe by means of a permanent soldered connection. Manufactured for use with copper and compatible metal piping, this reducing coupler provides a compact transition between two different diameters and is intended for heating, plumbing and industrial fluid systems where a secure, leak-resistant reduction is required.
Advantages
The reducing soldered coupler offers a robust, permanent joint when properly soldered, minimizing the risk of leaks and mechanical loosening. Its concentric reduction profile provides smooth flow transition between pipe sizes, helping to limit turbulence. Made by a recognized manufacturer of plumbing components, the fitting is compatible with standard soldering techniques and common fluxes for copper and similar metals.
Suitable for
 Connecting copper or compatible metal pipes from 54 mm to 35 mm diameter
 Domestic and commercial heating systems
 Plumbing supply and distribution lines where a size reduction is required
 Industrial fluid systems with soldered metal pipework
When it may not be suitable
This reducing coupler is intended for soldered connections; it is not suitable for push-fit, compression, or threaded installations. It should not be used with plastic piping unless an appropriate transition fitting and method are applied. Applications requiring frequent disassembly or adjustment are not ideal since the soldered joint is permanent.
Key specifications
 Connection diameters: 54 mm (larger end) and 35 mm (smaller end)
 Material compatibility: copper and compatible metal pipes suitable for soldering
 Joint type: soldered (permanent)
 Flow type: concentric reduction for inline transitions
 Typical applications: heating, plumbing, industrial fluid systems
How to use
Prepare pipe ends by cutting square and cleaning internal and external surfaces with an appropriate abrasive or brush to remove oxidation and contaminants. Apply suitable flux to both pipe and fitting contact surfaces. Assemble the fitting onto the pipes and heat the joint evenly with a torch until the flux is active and solder flows into the joint to form a continuous fillet. Allow the assembly to cool naturally, then remove flux residues and inspect the soldered joint for complete penetration and absence of visible voids. Follow applicable plumbing codes and safety practices during soldering.
What to consider before purchase
 Confirm compatibility with pipe material (copper or other solderable metals)
 Verify required diameters (54 mm and 35 mm) match the piping system
 Ensure soldering equipment, flux and solder alloy suitable for the system are available
 Check local regulations for soldered joints and use in heating or potable water systems
Usage recommendations
For durable, leak-free results, use correct flux and solder alloy for the pipe material, maintain clean surfaces, heat uniformly, and allow proper solder capillary flow. After cooling, pressure-test the system according to local standards before putting it into service.
