Conex nippel for soldered and threaded connections 22 x 1/2" copper

Conex nipple for soldered and threaded connections 22 x 1/2" copper is a plumbing fitting made from a brass/copper alloy designed to connect 22 mm copper tubing to a 1/2" threaded fitting or to be soldered directly into a copper pipe system. The component provides a secure transition between a soldered joint and a threaded connection and is intended for potable water, central heating and general plumbing installations where differing joint types must be combined.

Advantages

The Conex nipple combines a solderable copper end and a precisely machined 1/2" threaded end to ensure reliable sealing and mechanical strength. Its brass/copper alloy construction offers corrosion resistance and durability in typical domestic and light-commercial water and heating systems. The part simplifies installation by allowing a direct connection between copper tubing and standard threaded fittings without additional adapters.

Suitable for

• Domestic and commercial potable water supply systems
• Central heating installations and radiators
• Plumbing repairs where a transition between solder and thread is required
• New build plumbing where 22 mm copper pipe must connect to 1/2" threaded valves or fittings

Key specifications

• Material: brass/copper alloy suitable for soldering and threaded connection
• Tube connection size: 22 mm (for soldering to copper pipe)
• Thread size: 1/2" external thread for standard plumbing fittings
• Application media: potable water and heating fluids
• Typical use temperature range: suitable for domestic hot and cold water and central heating systems

How to use

Prepare the 22 mm copper pipe by cutting square and cleaning the outside with an appropriate brush or abrasive cloth to remove oxides and contaminants. Flux the cleaned end, insert the nipple and heat evenly to form a reliable solder joint. For the threaded end, apply an appropriate sealing method such as PTFE tape or pipe sealant to the male or female threads as required, then tighten to the manufacturer's recommended torque or until a leak-tight connection is achieved. Follow standard plumbing practice for support, alignment and testing of the completed connection.

Usage recommendations

Use only fluxes, solders and sealants compatible with potable water systems where required. After installation, perform pressure and leak tests before putting the system into regular service. Ensure installation complies with local plumbing codes and manufacturer guidelines for materials and operating conditions.
