Conex reducing coupler 5000 series 22 x 15 mm

Conex reducing coupler 5000 series 22 x 15 mm is a mechanical transition fitting designed to join pipes of different diameters. It provides a compact, robust connection between 22 mm and 15 mm copper or compatible metal pipes in plumbing and heating installations. The coupler is intended for situations where a reliable reduction in diameter is required without the need for soldering or complex jointing methods.

Advantages

The reducing coupler offers a secure mechanical joint that simplifies installation and reduces on-site assembly time. Its compact form factor saves space in tight pipe runs and allows for neat alignment between sections of differing diameters. The design ensures consistent flow transition and maintains system integrity under typical plumbing and heating pressures. Compatibility with common metallic pipe materials makes it a versatile component for renovation and new-build projects.

Suitable for

• Connecting 22 mm to 15 mm copper pipes in domestic plumbing
• Reducing pipe diameter in central heating systems
• Repairing or modifying existing metallic pipe runs
• Tight-space fittings where a compact reducer is required

Key specifications

• Series: 5000 series reducing coupler
• Connection sizes: 22 mm to 15 mm
• Intended pipe materials: copper and compatible metal pipes
• Type: mechanical reducing coupler for direct jointing
• Typical applications: plumbing and heating systems

How to use

Prepare pipe ends by ensuring they are clean, free of burrs and properly cut to length. Slide the coupler onto the larger or smaller pipe end as appropriate and align the pipes to achieve a straight joint. Follow the manufacturer's installation guidance for securing the mechanical connection, which may include compression, set-screw, or similar fastening methods depending on the specific product variant. After assembly, verify alignment and check for tightness according to system pressure requirements before placing the line into service.

Usage recommendations

Use the reducing coupler in systems with compatible metals and within the pressure and temperature ranges typical for domestic plumbing and central heating. Inspect joints after installation and periodically in service. Do not use the coupler where dissimilar metals could cause galvanic corrosion without appropriate isolation, and avoid exposure to aggressive chemicals or environments not suited to metallic fittings.
