Reducer coupling Conex series 5000 35 x 22 mm

Reducer coupling Conex series 5000 35 x 22 mm is a metal fitting designed to connect pipes of different diameters, enabling a reliable transition between a 35 mm line and a 22 mm line. Intended for use in plumbing and heating systems that accept Conex series 5000 fittings, the reducer provides mechanical strength, flow continuity and a tight joint when installed according to system requirements. The coupling is suitable for both new installations and retrofit work where reduction of pipe diameter is required.

Advantages

The reducer coupling offers a compact and robust metal construction that ensures long-term mechanical stability and resistance to typical operating conditions in domestic and light commercial plumbing or heating circuits. Its design facilitates a secure connection between dissimilar pipe sizes while maintaining flow characteristics and minimizing potential leakage points when correctly fitted. Compatibility with the Conex series 5000 range simplifies system planning and component interchangeability.

Suitable for

• Connecting 35 mm supply pipes to 22 mm distribution pipes in heating systems
• Plumbing installations requiring a reliable diameter reduction
• Retrofitting or repairs where an existing larger pipe must be reduced to a smaller size
• Commercial and residential water or heating circuits using Conex series 5000 components

Key specifications

• Material: metal fitting suitable for plumbing and heating use
• Nominal sizes: 35 mm to 22 mm diameter transition
• Design: reducer coupling for inline diameter reduction
• Compatibility: intended for systems compatible with Conex series 5000 fittings
• Application: suitable for potable water, heating circuits and general plumbing where system materials permit

How to use

Prepare both pipe ends by cutting square and deburring to ensure a clean fit. Slide the coupling into position so that each pipe engages fully with the corresponding end of the reducer. Install according to the Conex series 5000 installation method appropriate for the system—this may involve compression, push-fit, or soldering techniques depending on the exact variant and piping material. After assembly, verify alignment and perform any required pressure or leak tests per local regulations and installation guidelines.

Usage recommendations

Use the reducer coupling only with compatible Conex series 5000 components and materials. Confirm the fitting type and installation method match the pipe material (e.g., copper, metal, or approved plastics) and system operating parameters such as pressure and temperature. Follow local codes and manufacturer instructions for pressure testing and thermal cycling limits to ensure a durable, leak-free connection.
