Compression straight coupling Conex 22x22 mm brass GG-1020301--

The Conex compression straight coupling 22x22 mm is a brass mechanical fitting designed to join two pipes of equal 22 mm outside diameter. Manufactured for use in plumbing and heating systems, this coupling creates a sealed joint without the need for soldering or welding. Its brass construction provides corrosion resistance and dimensional stability for connections in potable water, heating circuits and general domestic pipework where a reliable, compact union is required.

Advantages

The coupling enables a quick, tool-assisted installation that eliminates the need for heat or special brazing equipment, reducing installation time and safety risks. Brass material offers good resistance to corrosion and scale in water systems while maintaining mechanical strength at typical domestic temperatures and pressures. The design provides a compact footprint and a consistent sealing mechanism suitable for metal and compatible plastic-lapped pipe ends when used with the correct olive or ferrule.

Suitable for

• Joining two 22 mm diameter copper or compatible pipes in domestic plumbing
• Linking sections in central heating circuits and radiator pipework
• Potable water distribution where a mechanical compression joint is preferred
• Temporary or permanent repairs to straight runs without re-soldering

Key specifications

• Material: brass body providing corrosion resistance
• Connection type: straight compression coupling for mechanical sealing
• Pipe compatibility: for pipes with 22 mm outside diameter
• Application: potable water, heating systems and general domestic pipework
• Installation method: compression fitting—no soldering required

How to use

Prepare the pipe ends by cutting square and removing burrs, ensuring both pipes are clean and correctly sized for a 22 mm compression joint. Slide the nut and ferrule (olive) onto each pipe as specified by the fitting manufacturer, insert pipe ends into the coupling fully, then hand-tighten the nuts before applying the recommended final torque with a spanner. After tightening, check alignment and pressure-test the system according to local plumbing regulations to verify a leak-free seal.

Usage recommendations

Use this coupling with properly sized ferrules/olives and follow manufacturer torque guidance to avoid overtightening. Do not use on damaged or heavily corroded pipe ends. For mixed-material joints, verify compatibility and, if required, use an appropriate insert or liner for plastic pipes. Pressure-test the installation before concealment and follow applicable local standards for potable water and heating systems.
