Conex fitting nippel for soldered and threaded connections 15x3/4" bronze

The Conex fitting nippel for soldered and threaded connections 15x3/4" bronze is a dual-purpose pipe connector designed to join a 15 mm soldered copper line to a 3/4" threaded fitting. Constructed from bronze, the fitting offers corrosion resistance and mechanical strength suitable for water and heating installations. Its configuration allows a secure transition between soldered connections and standard BSP-threaded components without additional adapters.

Advantages

This bronze nippel combines soldered and threaded interfaces in a compact component, simplifying installation where a change from a 15 mm copper tube to a 3/4" threaded fitting is needed. Bronze material resists corrosion and provides durability in potable water and central heating systems. The design ensures leak-tight performance when assembled and appropriately sealed, and it is compatible with standard plumbing fittings and soldering procedures.

Suitable for

• Joining 15 mm soldered copper pipes to 3/4" threaded valves or fittings
• Potable water distribution systems
• Domestic central heating and radiator connections
• Plumbing repairs where a solder-to-thread transition is required

Key specifications

• Connection types: soldered 15 mm on one end, 3/4" threaded on the other
• Material: bronze for corrosion resistance
• Suitable media: cold and hot water, heating fluid compatible with bronze
• Installation method: requires soldering for the 15 mm side and standard thread sealing for the 3/4" side

How to use

Prepare the 15 mm copper pipe by cutting squarely, cleaning and applying flux to ensure proper soldering. Heat the joint evenly and apply suitable solder until a continuous fillet forms around the soldered end. For the 3/4" threaded connection, apply an appropriate thread sealant such as PTFE tape or liquid sealant to the male thread, then tighten by hand and finish with a spanner to the torque recommended for the mating fitting. After assembly, pressurize and inspect for leaks, re-tightening or re-soldering if required.

Usage recommendations

Use certified solder and flux compatible with potable water systems where required by local regulations. When installing in heating systems, ensure materials and sealants are compatible with the system fluid. Avoid excessive heating that could damage the bronze finish; follow standard plumbing safety and installation practices.
