Conex reducing coupling 5000 series 28 x 15 mm

Conex reducing coupling 5000 series 28 x 15 mm is a mechanical fitting designed to connect two pipes of different diameters in plumbing and heating systems. The coupling provides a reliable, leak-resistant transition from 28 mm to 15 mm pipework and is compatible with common metal and plastic pipe materials used in domestic and light-commercial installations. Its compact design allows installation in confined spaces where a direct reduction is required.

Advantages

The coupling offers a secure, mechanical joint that does not require soldering or flaring, reducing installation time and the need for hot works. Its precision-engineered components deliver consistent compression and sealing performance across repeated installations. The compact form factor minimizes the space needed for pipe routing and helps maintain system aesthetics. The product is suitable for use in potable water and heating circuits when installed according to local regulations and compatible system components.

Suitable for

• Transitioning between 28 mm and 15 mm pipes in plumbing systems
• Heating system connections where pipe diameter reduction is required
• Repair or retrofit work in restricted spaces
• Applications with metal or compatible plastic pipe materials

Key specifications

• Series: 5000 series reducing coupling
• Connection sizes: 28 mm to 15 mm
• Type: Mechanical compression/reducing coupling
• Compatibility: Suitable for common metal and compatible plastic pipes
• Typical applications: Plumbing and heating installations

How to use

Prepare both pipe ends by cutting square and deburring to ensure proper seating. Slide the coupling components onto the pipe ends according to manufacturer guidance and tighten to the recommended torque or until the compression seal is made. Verify alignment and ensure that the pipe insertion depths meet the coupling's requirements. After installation, perform a pressure or leak test in line with applicable codes to confirm a watertight connection.

Usage recommendations

Use with pipes that match the specified 28 mm and 15 mm dimensions, inspect seals and compression rings before installation, and follow local plumbing regulations and the manufacturer's assembly instructions. Avoid excessive tightening to prevent deformation of pipe ends or sealing elements.
