## Summary description

Conex reducer coupling from series 5000 with dimensions 35 x 18 mm. Designed to join pipes of different diameters, this mechanical fitting ensures a secure transition between 35 mm and 18 mm lines. Suitable for plumbing and heating installations where a reliable diameter reduction is required; compatible with common pipe materials and used in repair or new-build applications.

## Long description

The Conex reducer coupling 35 x 18 mm, series 5000 provides a compact mechanical solution for joining pipes of different diameters. Engineered to create a secure transition from a 35 mm line to an 18 mm line, this fitting is intended for plumbing and heating systems where a reliable reduction is required. It is compatible with common pipe materials and can be used during repairs or in new-build installations.
Advantages
The coupling offers a robust mechanical connection between dissimilar pipe sizes without requiring soldering or complex tooling. Its compact design minimizes space requirements and facilitates installation in confined areas. The product is designed for consistent performance in domestic and light commercial plumbing and heating applications, ensuring leak-resistant joins when installed correctly.
Suitable for
Connecting a 35 mm pipe to an 18 mm pipe in plumbing systems
Heating system manifolds and branch line connections
Repair work where diameter reduction is necessary
New-build installations requiring reliable mechanical fittings
Key specifications
Connection sizes: 35 mm to 18 mm
Series: 5000
Function: mechanical reducer coupling for diameter transition
Typical applications: plumbing and heating systems
Installation: suitable for confined spaces due to compact form factor
How to use
Prepare the pipe ends by ensuring they are clean, cut squarely and free from burrs or debris. Insert each pipe into the corresponding end of the reducer coupling until it reaches the designated stop, following any depth markers or manufacturer guidance. Secure the connection according to the system type—this may involve tightening compression fittings, securing with appropriate clamps, or following the mechanical joining method specified for the series 5000 coupling. After installation, pressure-test the circuit as required by local regulations to verify a leak-free connection.
Usage recommendations
Confirm material compatibility between the coupling and the pipes to avoid galvanic corrosion or degradation; follow applicable plumbing and heating standards, use appropriate installation tools, and perform a pressure test after fitting. For installations in concealed or high-temperature environments, verify the suitability of mechanical couplings for the specific service conditions.
