Conex reducer coupling 35 x 18 mm, series 5000

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.
